Description
Technical field
The present invention relates to a kind of time-delay lubricating device, the delay lubricating coupler of specially a kind of engine supercharger.
Background technology
It is an important technological progress of Modern Engine using air-admission pressure-booster.By compressed air, carry
The density of the induced air of high engine, so as to improve the power per liter of engine.Simultaneously because the mixed combustion of engine is adjusted
Improvement has been arrived, efficiency of combustion has been improved, the effect for saving fuel oil and reduction discharge can also have been played.Now using it is most common just
It is the Studying about Turbocharger of Engine device, exhaust-driven turbo-charger exhaust-gas turbo charger, 700-900 degrees Celsius of the high temperature discharged using engine is given up
Turbine rotation in gas, driving turbine, turbine wheel shaft drives the impeller in compressor to rotate at a high speed, compresses empty in eccentric fashion
Gas, improves the density of the induced air of engine to 2-3 atmospheric pressure.So as to we can spray more fuel oils to engine, reach and carry
The purpose of engine own power high.
Engine work when, some engine oil supplying turbocharger rotor bearing lubrication and for cool down.
After the engine of operation is shut down suddenly, engine oil pressure drops to rapidly zero, and the high temperature of booster turbine part passes to centre, bearing
Heat in supporting shell can not be taken away rapidly, and supercharger rotor still rotates at a high speed under effect of inertia simultaneously, therefore, engine
If shut down suddenly under heat engine state, the machine oil being detained in turbocharger overheat can be caused and bearing and axle is damaged.Therefore increase
After the hydraulic motor requirement engine long time runs at high speed, it is impossible to stop working immediately, be important to prevent suddenly Hong after several foot throttles suddenly
It is flame-out.
But in use, driver often ignores the requirement that engine with supercharger can not stop working immediately, usually because hair
Motivation run at high speed for a long time after it is flame-out suddenly, cause the bearing and axle sintering of booster to damage.
The content of the invention
The present invention is in order to solve after engine stop work, and there is provided one kind hair the problem of the machine oil sustainable supply of turbine
The delay lubricating coupler of motivation booster.
A kind of time delay lubricating coupler of engine supercharger, including base, filter, one-way throttle valve, shell are stored in oil
Capsule, base is respectively provided on two sides with oil inlet, and oil-out, middle part is provided with one-way throttle valve mounting hole；One-way throttle valve is provided with section
Discharge orifice, the unidirectional oil-out of one-way throttle valve, one-way throttle valve screw thread, described filter is located at base lower section, oil inlet and mistake
Filter is connected, and filter is connected with oil-out, and one-way throttle valve is installed in one-way throttle valve mounting hole, and storage is provided with above base
Oily capsula interna, shell, described one-way throttle valve is located in the interface channel of filter and oil-out, respectively by one-way throttle valve
Unidirectional oil-out connect with oil-out, and one-way throttle valve screw thread is connected with filter, the throttle orifice that one-way throttle valve is provided with
Store oily capsula interna connection.
The present invention is simple in construction, easy for installation, do not change original lubricating pipe, after engine misses, can continue as
Booster provides a certain amount of lubricating oil, it is possible to prevente effectively from the engine supercharger caused by flame-out suddenly is damaged.
