The present invention provides a kind of rotor-type oil pumps of energy oil suction in time, including the pump housing, pump cover, transmission gear, armature spindle and internal rotor and outer rotor on armature spindle, one end of the armature spindle is mounted in the axis hole of the pump housing, the other end is mounted in the axis hole of pump cover, transmission gear is mounted on the end of armature spindle either end, bushing is mounted in the axis hole of the pump housing and pump cover, the air discharge duct of an axial direction, the oil outlet end for being located proximate to lubricating oil pump of the air discharge duct are equipped between the axis hole wall of its middle pump body and the peripheral surface of bushing.The beneficial effects of the invention are as follows：By increasing an air discharge duct in oil outlet end, with regard to that the gas in confined space can be made to be discharged in time from air discharge duct, so as to which oil pressure is established in rapid oil suction in oil pump initial start, check valve is opened under the action of oil pressure, and fluid gets enter into oil leab and engine is lubricated.
Description
Technical field
The present invention relates to a kind of engine lubrication system component, more particularly to a kind of rotor-type oil pump.
Background technology
Rotor-type oil pump is made of the pump housing, armature spindle, internal rotor, outer rotor and pump cover etc..Internal rotor is fixed on rotor
It on axis, is directly or indirectly driven by crankshaft toothed wheel, internal rotor and outer rotor eccentric setting, internal rotor drive outer rotor together along same
One direction rotates.Total energy mutually holding point contact condition on the tooth form line of each tooth of inner and outer Rotator, in this way, inside and outside
Just several working chambers are formed between rotor.When some working chamber is turned over from oil sucting cavity, volume increase generates vacuum, machine oil
Working chamber is inhaled into from fuel feed hole, with being rotated further for inner and outer Rotator, when which goes to the position that pumping cavity communicates,
Volume becomes smaller, and oil pressure raising, machine oil is pressed into from oil outlet in oil leab through pumping cavity.
Since the oil outlet end of this lubricating oil pump has a check valve on the engine, only check valve can just make oil pump after opening
The fluid of oil outlet end is by lubricating engine, but check valve needs to open under pressure.In oil pump initial start
When, it is an approximate closed space because of the presence of check valve, between the oil outlet end and check valve of oil pump, in this way when oil pump turns
After son starts rotation, because of the presence of confined space, working chamber can not timely oil suction, it is impossible to establish oil pressure rapidly, check valve is difficult
To open, finally result in engine and can not be successfully startup even part of damage.
Invention content
The technical problem to be solved in the present invention is to provide a kind of rotor-type oil pumps for being capable of oil suction in time.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：A kind of rotator type machine of energy oil suction in time
Oil pump, including the pump housing, pump cover, transmission gear, armature spindle and internal rotor and outer rotor on armature spindle, the rotor
One end of axis is mounted in the axis hole of the pump housing, and the other end is mounted in the axis hole of pump cover, and it is arbitrary that transmission gear is mounted on armature spindle
The end of one end, is mounted on bushing in the axis hole of the pump housing and pump cover, the axis hole wall of middle pump body and the peripheral surface of bushing it
Between be equipped with the air discharge duct of axial direction, the oil outlet end for being located proximate to lubricating oil pump of the air discharge duct.
In one embodiment, the air discharge duct is opened on the axis hole wall of the pump housing.
In one embodiment, the air discharge duct is opened on the peripheral surface of bushing.
Preferably, the section of the air discharge duct is crescent.
Preferably, the outer rotor is equipped with multiple oil-through holes.
The beneficial effects of the invention are as follows：As soon as by increasing an air discharge duct in oil outlet end, can make in oil pump initial start
Gas in confined space is discharged in time from air discharge duct, so as to which oil pressure, check valve quilt under the action of oil pressure are established in rapid oil suction
It opens, fluid gets enter into oil leab and engine is lubricated.
