Abstract

PURPOSE: A hydraulic pressure generator is provided to prevent pneumatic pressure from mixing to working fluids through a seal of a piston when pressurizing working fluids with pneumatic pressure using a piston, and to fill up working fluids easily without using a pump to a working fluid storage chamber. CONSTITUTION: In a hydraulic pressure generator, a check valve(8) and a pneumatic pressure chamber(10b) are formed between seals(11,12) of a piston(3) to cut off the space between a working fluid storage chamber(10c) and a pneumatic pressure chamber(10a) connected with a hydraulic pressure passage(20), and pneumatic pressure of the pneumatic pressure chamber comes in the pneumatic pressure chamber to apply pneumatic pressure to the seal always to make the seal adhere closely to a tube, and the pneumatic pressure chamber is connected with a pneumatic pressure passage(10) to discriminate the level of working fluids with the naked eye using a push knob(4) integrated with the piston and to extend the piston manually when injecting to the working fluid storage chamber.

Description

         Oil pressure generating device

           The existing hydraulic generator is a method of contacting the pneumatic fluid to the hydraulic fluid, this method has been used at low speed because of the possibility of mixing the pneumatic pressure into the hydraulic fluid, even if it is blocked by a piston between the hydraulic fluid and the pneumatic pressure, but the present invention is pneumatic in the piston By forming the operating chamber (10b), it is possible to block the sharing, it is possible to check the flow rate of the hydraulic fluid with the push knob, it is a technology to manually return the piston when the hydraulic oil is injected.

           A pneumatic operating chamber (10b) is formed between the seals of the pistons, which disconnects between the hydraulic oil storage chamber and the pneumatic operation chamber so that the seals are always pressurized to ensure that the seals are in close contact with the tube. The piston is manually extended when the hydraulic oil is injected.

             When pressurizing the hydraulic oil with the piston by pneumatic pressure, it is a problem to prevent the pneumatic pressure from being mixed into the hydraulic oil through the seal of the piston, and to easily replenish the hydraulic oil without using a pump in the hydraulic oil storage chamber.

             A pneumatic operation chamber (10b) is formed between the seals of the piston, which blocks the hydraulic oil storage chamber and the pneumatic operation chamber, so that the seal is always applied with air pressure so that the seal is in close contact with the tube and the piston is formed integrally with the piston. It is a push knob.

        Conventional hydraulic generators, but in order to prevent the mixing of the pneumatic and hydraulic fluid, the hydraulic cylinder was operated at a low speed, the present invention enables more than three times the operation than the existing method, and minimizes the consumption of the hydraulic oil.

         A feature of the present invention for achieving the above object is the seal 11 of the piston 3, which blocks between the hydraulic oil storage chamber 10c communicating with the hydraulic passage 20 and the pneumatic operation chamber 10a in front, ( 12, a check valve 8 and a pneumatic operation chamber 10b are formed between them, so that the pneumatic pressure of the pneumatic operation chamber 10a flows into the pneumatic operation chamber 10b through the check valve 8 and enters the seal 11. Always pressurize the seal so that the seal 11 is brought into close contact with the tube 9, the pneumatic operation chamber 10a is in communication with the pneumatic passage 10, and the operating oil is formed by the push knob 4 formed integrally with the piston 3 The level is visually identified and formed to manually expand the piston 3 upon injection into the hydraulic oil reservoir 10c.

        Injection port Marguerite (6), (7) is always formed at right angles to the upward position depending on the installation position.

         Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

          1 to 3 is a view showing a hydraulic generating apparatus according to an embodiment of the present invention.

          Referring to the embodiment of the present invention, Figure 1 is a state in which the hydraulic fluid introduced into the hydraulic passage 20 is introduced into the hydraulic oil storage compartment (10c).

           In FIG. 2, the pneumatic pressure introduced into the pneumatic passage 10 acts on the pneumatic operation chamber 10a to advance the piston 3 and the push knob 4 to transfer the hydraulic oil of the hydraulic oil storage chamber 10c into the hydraulic passage 20. Discharge.

            At this time, the pressing knob 4 is also advanced in accordance with the advance of the piston (3).

           In FIG. 3, the pneumatic passages 30 and 40 between the seals 11 and 12 pass through the piston 3 to exhaust the pneumatic pressure from the pneumatic operation chamber 10a.

1 is a longitudinal sectional view of a hydraulic generator according to an embodiment of the present invention.

Figure 2 is a longitudinal sectional view showing the advance of the hydraulic generator.

3 is a longitudinal sectional view showing the pneumatic passages 30 and 40 of the hydraulic generator.
