Definitions
- the invention relates to a pump, in particular for a hydraulic brake control system, with a pump housing which has at least one working space and a valve bore connected to the working space, in which an inlet valve and an outlet valve, each with a fixed valve seat and a movable closure element, are arranged one behind the other, and with a displacement element that can be moved back and forth and changes the volume of the working space due to its movement.
- the inlet and outlet valves are designed as ball seat valves, the valve seat being formed in each case by a step-like expansion of the valve bore in the pump housing.
- Design measures, for simple manufacture of the valve bore and for simple assembly and testing of the valves are not specified.
- the pump has a piston which is guided and sealed in a cylinder bore crossing the valve bore and can be driven by an eccentric in the pressure direction and a spring in the suction direction.
- a piston pump in which the inlet valve and the outlet valve each in one separate stepped bore are arranged, which is connected to the work space by a connecting bore.
- Inlet and outlet valves are formed by different valve inserts, which include the fixed valve seat, the movable closure element and a valve spring.
- machining of the stepped bores and assembly of the valve inserts from opposite sides of the pump housing are required. This has an unfavorable effect on the manufacturing costs and considerably limits the design options of the designer, for example with regard to the structural union of the pump housing with the housing of a valve block.
- the invention has for its object to provide a pump of the type mentioned, which is characterized by a low manufacturing and assembly costs and which can be easily integrated into the housing of a hydraulic unit.
- valve seat, the closure element and a valve spring pressing the closure element against the valve seat of the inlet valve and the outlet valve are connected to one another in a valve-tight insertable cartridge and that the cartridges of both valves from the same side in the valve bore can be used and can be supported by a step in the valve bore in the installation direction on the pump housing. If the design of the pump permits it, it can further be provided that the cartridges of both valves are supported on one another.
- a particularly simple embodiment of the invention can also consist in that the valve seat, the closure element and the valve spring of the inlet valve and outlet valve into a single, in the Valve bore tightly insertable cartridge are interconnected.
- the design of the pump according to the invention has the advantage that the valve bore can be produced in a single operation and the valves can be assembled from one side of the pump housing. If the cartridges are not spaced apart, the valves can also be assembled in a single operation. This reduces the manufacturing costs and simplifies the placement of the pump in a housing provided for further components. It is also of particular advantage that the valves in the pre-assembled cartridges can be checked before installation, so that manufacturing errors can be recognized early and the installation of faulty parts can be avoided. If both valves, the inlet valve and the outlet valve, are accommodated in a common cartridge, the number of valve components and the installation space can thereby be significantly reduced.
- the cartridge can be put together from several parts.
- the cartridge can have a housing or a housing part made of a material of lower strength, for example aluminum or free-cutting steel, which is connected to a valve seat ring made of a material of higher strength, for example hardened steel.
- the cartridge can be held and sealed in the valve bore in various ways.
- An advantageous type of fastening is the caulking of the cartridge in the valve bore.
- the cartridge or cartridges are inserted from the high-pressure end into the valve bore, so that the valves are acted upon in the closed position by the pump pressure in the installation direction, in which they move over a step in the Support the valve bore on the pump housing.
- the cartridges can be sealed with metal by means of appropriately shaped seats or with the help of sealing rings.
- a particularly advantageous fastening and sealing can be achieved according to the invention in that the rear end of the cartridge, as seen in the direction of insertion, has a sleeve-shaped section and that it can be expanded by pressing a plug into the sleeve-shaped section and can therefore be non-positively and tightly fastened in the valve bore.
- the pump has a damping chamber adjoining the outlet valve, it is advantageous if the cartridge is inserted from the damping chamber.
- a compression spring can then be used to fix the cartridge or cartridges in the installed position, which is inserted into the damping chamber and which is supported on the end of the cartridge which projects into the damping chamber.
- FIG. 1 shows a cross section through a radial piston pump designed according to the invention
- FIG. 2 shows a partial section through a radial piston pump according to the invention, which is installed in the housing of a hydraulic unit,
- FIG. 3-7 partial sections of the radial piston pump according to Figure 2, each with different embodiments of the cartridges forming the inlet and outlet valve.
- the radial piston pump 1 shown in FIG. 1 has a pump housing 2 with a central bearing bore 3, in which a drive shaft 4 is rotatably mounted by means of a ball bearing 5.
- An eccentric 6 is formed on the drive shaft 4 and drives two pistons 8, 9 via a needle bearing 7.
- the pistons 8, 9 are guided in cylinder bores 10, 11 arranged radially to the bearing bore 3, the radially outer ends of which are closed by plugs 12, 13.
- the cylinder bores 10, 11 each form a working space 14, 15 which is penetrated by a valve bore 16, 17 which is parallel or perpendicular to the bearing bore 3.
- a compression spring 18 which presses the piston 8 against the needle bearing 7 and effects the suction stroke of the piston 8.
- the compression spring 18 is guided on a pin 19 of the plug 12 projecting into the working space 14.
- the suction stroke of the piston 9 is effected by a resilient coupling ring 20 which is supported on the needle bearing 7 and presses the piston 9 against its outer ring.
- valve E is arranged in the valve bore 16 between the working chamber 14 and the bore section 21 leading to a low pressure chamber and an outlet valve A between the working chamber 14 and a bore section 23 leading to a high pressure chamber.
- Both valves E, A are designed in the same way as cartridges 22, 24 and consist of a sleeve-shaped housing 25, the bore of which forms a valve seat 26 and contains a valve ball 27, a valve spring 28 and a valve disk 29 with spring guide pins.
- the valve plate 29 is fastened in the bore of the housing 25 by caulking and has segment-shaped recesses on its edge for the formation of pressure medium passages.
- the cylindrical outer surface of the housing 25 has its rear in the insertion direction

- the sleeve 83 has a sleeve bore 86 which extends from the low-pressure side to the high-pressure side in two valve seats 84, 85, the middle section of which is connected to the working space 51 by a transverse bore 87.
- a valve plate 88 is assigned to the valve seat 84 and a valve ball 89 is assigned to the valve seat 85. Between the valve plate 88 and the valve ball 89 there is a weaker valve spring 90 and between the valve ball 89 and that which is pressed into the end of the sleeve bore 86 facing the damping chamber 47. Plug 91 is clamped into a stronger valve spring 92.
- the sleeve 83 can be sealed in the valve bore 50 with the aid of a sealing ring 93 (upper half of the drawing) or also without a sealing ring made of metal (lower half of the drawing). Sealing on the high-pressure side takes place by pressing the plug 91 into the sleeve bore 86, the sleeve section surrounding the plug 91 being widened slightly and pressed metallically tight against the wall of the valve bore 50. At the same time, the cartridge 82 is non-positively fastened in the valve bore 50 by pressing in the plug 91.
- a metallic seal is also achieved between the low-pressure side end face of the sleeve 83 and the step 73 of the valve bore 50.
- the plug 91 can be pressed in either with a stop (below the drawing) or without a stop (upper drawing).
- the exemplary embodiment according to FIG. 7 differs from the exemplary embodiment according to FIG. 6 only by the different shape of the plug 94 which, in contrast to the plug 91, has a neck section 95 in which the valve spring 92 is guided.
- the exemplary embodiments described are characterized above all by simple manufacture, preassembly and assembly of the inlet and outlet valves in the housing. Both valves can be installed from one side of the housing, which also simplifies the design of the pump housing.
- the valves, which are designed as cartridges, require only a small installation space and can extend into the work space, as a result of which the dead space of the work space is reduced and the self-ventilation of the pump is improved.
- the shape of the cartridge also enables the entire valve unit to be checked easily before installation. It is also particularly suitable for a simple and permanent metallic seal in the pump housing.
- the number of components and thus also the cost of manufacturing and assembling the valves can be reduced.
