Background technology
The front cover shell of automobile engine is generally integrated organic oil pump, comprising housing, pump cover, internal rotor, outer rotor, interior turn
Sub- axis, machine oil pump sprocket, pressure limiting valve etc., are designed with oil duct on housing, and internal rotor, outer rotor assembling are sent out on housing
Motivation at work, the relative motion surface such as armature spindle of driving parts and base bearing, piston and cylinder wall, timing gear wheel set etc.
Between necessarily lead to friction, the friction between metal surface can not only increase the power consumption of engine interior so that part work
Make surface to wear rapidly, and due to friction generate heat be also possible to lead to part time job surface scaling loss, cause engine without
Method operates, therefore, to ensure engine work, it is necessary to relative motion surface be lubricated, that is, in friction surface
Covering one layer of lubricating oil machine oil so that metal surface covers one layer of thin oil film, to reduce frictional resistance, reduces power attenuation,
Mitigate component wear, increasing service life of engine.But in the structure of the lubricating oil pump of the prior art, the low pressure oil pocket of lubricating oil pump
It is located at the opposite sides of rotor mechanism with high-voltage oil cavity, structure owes compact so that the volume of lubricating oil pump is relatively large, occupied space
Greatly, and in order to avoid the oil sealing being arranged on rotor of engine oil pump seat is washed away extruding displacement by extra lubricating oil, it is also necessary to set
It puts individual oil return hole and carries out oil return, complicated and processing is cumbersome.
At present, engine oil pump is independently mounted on cylinder body, complete machine parts is caused to increase, and axial space is not tight
It gathers.Most engine oil pumps are constant flow lubricating oil pump, and how much is rotor acting, and lubricating oil pump just conveys how many machine into main oil gallery
Oil.When engine speed rises, pump oil amount increases, and main oil gallery pressure raising, lubricating oil pump oil extraction resistance increases.But engine is each
Surface of friction pair has not needed to convey excessive machine oil, and because oil pump capacity is only related with rotating speed, rotating speed rises, and flow adds
Greatly, oil discharge outlet resistance just increases.
