Abstract
The utility model discloses an internal leakage type high-power oil pump which comprises an oil inlet channel and an oil return channel formed in a pump body and is characterized in that a pressure relief oil duct for connecting the oil inlet channel and the oil return channel is also formed in the pump body; a pressure relief valve is arranged in the pressure relief oil duct; when the pressure of the oil duct is boosted, the internal leakage type high-power oil pump can cause oil to be subjected to pressure relief and flow to the oil inlet channel backwards so as to avoid the outward leakage of the oil and the environment pollution.
Description
Technical field
The utility model relates to a kind of oil pump of high power engine.
Background technique
Powerful general gasoline engines generally adopts oil pump that lubricant oil and each transmission of cleaned engine of steady pressure are provided, and reduces the inordinate wear of transmission, takes the chamber wall heat to tank surface simultaneously, improves engine life; At present only be provided with separate oil inlet passage and drainback passage in the pump housing of the oil pump of using, when petrol engine ran up, oil circuit pressure raise, fluid very easily from each sealing part to external leakage, befouling environment.
The model utility content
The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of internal drainage type high-power oil pump, and when oil circuit pressure raise, it can be back to oil inlet passage with the fluid pressure release, avoided fluid to external leakage and befouling environment.
For achieving the above object, the high-power oil pump of internal drainage type of the present utility model is provided with oil inlet passage and drainback passage in the pump housing, it is characterized in that also being provided with the pressure release oil duct that connects oil inlet passage and drainback passage in the pump housing, is provided with Decompression valves in the pressure release oil duct.
Above-mentioned Decompression valves comprises spool, guide rod, be loaded on the guide rod and the spring that contacts with spool, the positioning block that fixedly installs.
During use, when petrol engine ran up, oil circuit pressure raise, and Decompression valves is opened, and fluid is back to oil inlet passage, avoids fluid to external leakage and befouling environment.
As further improvement of the utility model, on spool, be provided with several closure gasket groove, can improve the sealability of Decompression valves.
In sum, when oil circuit pressure raise, the utility model can be back to oil inlet passage with the fluid pressure release, avoided fluid to external leakage and befouling environment.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment pump housing.
Fig. 2 is the structural representation of the utility model embodiment Decompression valves.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The high-power oil pump of this internal drainage type by shown in Figure 1, comprises the pump housing 1, and the pressure release oil duct 4 that is provided with oil inlet passage 2, drainback passage 3 in the pump housing and connects oil inlet passage 2 and drainback passage 3 is provided with Decompression valves in pressure release oil duct 4; By shown in Figure 2, described Decompression valves comprises spool 5, guide rod 6, be loaded on the guide rod 6 and the spring 7 that contacts with spool 5, by the positioning block 8 that bearing pin 9 fixedly installs, on spool 5, also be provided with five road closure gasket grooves 10.
During use, when petrol engine runs up, oil circuit pressure raises, fluid promotes to move behind spool 5 and the spring 7, Decompression valves is opened, and fluid is back to oil inlet passage 2 through pressure release oil duct 4, avoids fluid to external leakage and befouling environment, closure gasket groove 10 on the oil drain valve can improve the sealability of Decompression valves, avoids occurring climbing moving phenomenon.
