Fig. 2 is the structural representation that has the filter cleaner of voltage stabilizing function.
Embodiment
As shown in Figure 1, a kind of engine lubrication system, comprise the one-way valve 20 that is arranged on oil pump 10 output terminals, one-way valve 20 links to each other with the input end of stable-pressure device by oil feed line, the oil feed line that links to each other with the output terminal of stable-pressure device is divided into two, one the tunnel for the oil leab toward motor, and another road is for the oil leab toward turbosupercharger 80, and the machine oil after lubricating is delivered to fuel tank 30 through return line.
Machine oil is through oil pump 10 pressurizations during operation, by entering stable-pressure device behind the one-way valve 20, machine oil supplies respectively toward motor and turbosupercharger 80 after the output terminal output of stable-pressure device, and the two is lubricated, and the machine oil after lubricating is back to fuel tank 30 through return line.
Be communicated with overflow passage on the oil feed line between described one-way valve 20 and the stable-pressure device, overflow passage is provided with relief valve 40.
Being arranged so that when the oil pressure in the lubrication system raises suddenly of relief valve 40, machine oil in the system can be back to fuel tank 30 by relief valve 40, thereby reach the effect of oil pressure in the restriction lubrication system, prevent that turbosupercharger from producing oil leakage phenomenon because of oil pressure is too high.
The oil feed line that described stable-pressure device links to each other with motor is provided with the solenoid valve 50 of break-make pipeline.
The oil feed line that described stable-pressure device links to each other with turbosupercharger is provided with vacuum solenoid valve 60.
As preferred version of the present invention, described stable-pressure device comprises the pressure maintaining valve and the filter cleaner of mutual series connection.
This moment, filter cleaner only played the effect of filtering machine oil, and pressure maintaining valve then plays the effect of voltage stabilizing and storage pressure in whole lubricating system.
Further, the contacted end of described pressure maintaining valve and oil feed line is provided with piston, and piston can move along the direction that pressure maintaining valve limits, and described piston is arranged in the end face of pressure maintaining valve inside and presses voltage regulation part to link to each other with the storage that is arranged on pressure maintaining valve.
Described storage presses voltage regulation part can preestablish force value, and when the suffered pressure of pressure maintaining valve was lower than the predetermined pressure of storage pressure voltage regulation part, the state of pressure maintaining valve remained unchanged; When the suffered pressure of pressure maintaining valve was higher than the predetermined pressure of storage pressure voltage regulation part, piston was inner mobile to pressure maintaining valve along the direction that pressure maintaining valve limits, and makes the pressure maintaining valve internal capacity diminish, and it is to the energy storage effect; When the suffered pressure of pressure maintaining valve diminished, the direction that piston presses the effect lower edge pressure maintaining valve of voltage regulation part to limit in storage was outside mobile to pressure maintaining valve, made the pressure maintaining valve internal capacity become big, and it is to pressure stabilization function.
Described storage presses voltage regulation part can be chosen as pressure spring, and not only pressure is easy to set, and reliable operation, and cost is lower.
As another kind of preferred version of the present invention, described stable-pressure device is a filter cleaner 70, filter cleaner 70 comprises the filter chamber 74 that is communicated with oil feed line, be provided with filter core 71 in the filter chamber 74, described machine oil is transported to the oil leab in motor/turbosupercharger after filter core 71 filters, also be provided with the plenum 75 of adjusting oil feed line pressure in the described filter cleaner 70, as shown in Figure 2.
The filter cleaner 70 of this moment not only plays the effect of filtering machine oil, also plays the effect that voltage stabilizing and storage are pressed simultaneously.
Described plenum 75 is provided with piston 73 with the contacted end of oil feed line, and piston 73 can move along the direction that plenum 75 limits, and described piston 73 is arranged in the end face of plenum 75 inside and presses voltage regulation part 72 to link to each other with the storage that is arranged on plenum 75.
As shown in Figure 2, described storage presses voltage regulation part 72 can preestablish force value, when plenum 75 suffered pressure are lower than the predetermined pressure of storage pressure voltage regulation part 72, the state of plenum 75 remains unchanged, and guarantees that plenum 75 reaches the building-up time of needed oil pressure when not influencing engine start; When plenum 75 suffered pressure were higher than the predetermined pressure of storage pressure voltage regulation part 72, piston 73 was inner mobile to plenum 75 along the direction that plenum 75 limits, and makes the internal capacity of plenum 75 diminish, and it is to the energy storage effect; When plenum 75 suffered pressure diminished, the direction that piston 73 presses the effect lower edge plenum 75 of voltage regulation part 72 to limit in storage moved to the outside of plenum 75, progressively returns to initial position, made the internal capacity of plenum 75 become big, and it is to pressure stabilization function.
