Abstract
The utility model discloses an engine oil pump cover of an engine. The engine oil pump cover comprises an engine oil pump cover body in which an oil outlet running through the engine oil pump cover body is formed, wherein the oil outlet is connected with a pressure reducing valve arranged on the outer wall of the engine oil pump cover body. The engine oil pump cover has the advantages of ingenious structure design and convenience for manufacturing and use; due to the adoption of the engine oil pump cover, the oil pressure of an engine oil passage is kept in a proper state, an oil seal on the engine oil passage is protected from being damaged, the phenomenon of oil leakage at the joint of the oil passage is prevented, and the reliability of the engine is improved.
Description
Technical field
The utility model relates to a kind of engine oil pump, particularly a kind of motorcycle engine oil pump lid.
Background technique
At present, the major function of traditional engine motor oil pump cover is sealing machine pump body, makes the inner negative pressure that produces of oil pump, allows the normal pump oil of oil pump work.But for more existing novel high speed engines, traditional oil pump cover can not be useful in these high speed engines.Because, the performance characteristic of high speed engine makes it remain on for a long time a high-revolving working state, thereby oil pump is also thereupon at a high-speed state, make like this oil pressure in engine oil channel also remain on accordingly a high pressure conditions, in this high pressure conditions, some oil sealings to oil duct joint are caused damage for a long time, and cause the appearance of the problems such as oil duct joint oil impregnate, cause engine failure.
Model utility content
The purpose of this utility model is just to provide and a kind ofly can prevents the damaged motorcycle engine oil pump of oil sealing lid.
The purpose of this utility model is to realize by such technological scheme, a kind of engine motor oil pump cover, comprise oil pump cover body, on described oil pump cover body, be provided with the oil outlet that connects oil pump cover body, described oil outlet is connected with the reduction valve being arranged on oil pump cover body outer wall.
Wherein, described reduction valve comprises the reduction valve passage being communicated with oil outlet, in described reduction valve passage, be disposed with elastic cylindrical pin, packing ring, engine oil pressure valve spring and engine oil pressure valve steel ball, the two ends of described engine oil pressure valve spring withstand on respectively on packing ring and engine oil pressure valve steel ball, in described reduction valve vias inner walls and near fuel-displaced nose end, be provided with limit dais, described engine oil pressure valve steel ball is stuck in limit dais.
Owing to having adopted technique scheme; the utlity model has structural design ingenious, manufacture advantage easy to use; adopt it can make engine oil channel oil pressure remain on a suitable state; protected the oil sealing on engine oil channel; prevent that oil sealing is damaged; also prevented the generation of oil duct joint oil impregnate phenomenon, improved the reliability of motor simultaneously.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement on the present embodiment essence spirit or substitute, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of engine motor oil pump cover, comprise oil pump cover body 1, be provided with the oil outlet 2 that connects oil pump cover body 1 on described oil pump cover body 1, described oil outlet 2 is connected with the reduction valve being arranged on oil pump cover body 1 outer wall.
Further describe, described reduction valve comprises the reduction valve passage 3 being communicated with oil outlet 2, in described reduction valve passage 3, be disposed with elastic cylindrical pin 4, packing ring 5, engine oil pressure valve spring 6 and engine oil pressure valve steel ball 7, the two ends of described engine oil pressure valve spring 6 withstand on respectively on packing ring 5 and engine oil pressure valve steel ball 7, on described reduction valve passage 3 inwalls and near oil outlet 2 ends, be provided with limit dais 8, described engine oil pressure valve steel ball 7 is stuck in limit dais 8 places.
The utility model is to use like this: when oil pump rotating speed too high; oil pump oil outlet oil pressure can increase; oil pressure in oil outlet 2 on same oil pump cover body 1 also can increase; when oil pressure reaches can promote Decompression valves spring 6 time, Decompression valves steel ball 7 and limit dais 8 generation gaps, junction, make oil discharge oil duct from reduction valve passage 3; oil duct is carried out to pressure release; protection oil duct oil sealing, prevents that the phenomenons such as oil impregnate from appearring in oil duct joint, improves engine reliability.
