The variable lubricating oil pump of level and the engine assembly comprising it, concrete scheme is as follows：
A kind of two grades of variable lubricating oil pump, including rotor, outer regulation ring, pressure spring and two grades of variable lubricating oil pump wire harness；Institute
State and feedback pressure oil-in, oil pocket A, oil pocket B, electromagnetic valve are provided with inside two grades of variable lubricating oil pump；The oil pocket B by oil circuit with
Oil pocket A connects, and the oil circuit opening and closing passes through solenoid valve control.
A kind of engine assembly for including two grades of variable lubricating oil pump, wherein two grades of variable lubricating oil pump are arranged in electromotor gear oil
On plate assembly, while being fixed on engine cylinder-body together with electromotor oil baffle assembly.
Further, stretcher is provided with electromotor and extends oil circuit, the stretcher extends tensioning of the oil circuit from electromotor
Device oil circuit is drawn, and is connected with oil pocket A by the feedback pressure oil-in of two grades of variable lubricating oil pump, and oil pocket A is normally open.
Further, motor head timing chain cover is provided with wire harness socket.
Compared with prior art, a kind of two grades of variable lubricating oil pump and the electromotor comprising it that this utility model is provided is total
Into, by such scheme so that two grades of variable lubricating oil pump arrangements are compact, as far as possible keep traditional structure on the basis of realize work(
Can be integrated, be conducive to miniaturization and the lightweight of electromotor.Meanwhile, within the specific limits, realize electromotor actual engine oil pressure
Match with demand pressure as far as possible.The driving power for taking full advantage of lubricating oil pump avoids the waste of power, car load typical condition
Under oil consumption reduce by more than 1.5%.

Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one
As shown in Figure 2 and Figure 3, this utility model provides a kind of two grades of variable lubricating oil pump 2, including rotor 25, outer regulation ring
26th, pressure spring 27 and two grades of variable lubricating oil pump wire harness, inside two grades of variable lubricating oil pump 2 feedback pressure oil-in is provided with
23rd, oil pocket A21, oil pocket B22, electromagnetic valve 24；The oil pocket B22 is connected by oil circuit with oil pocket A21, and the oil circuit opening and closing is by electricity
Magnet valve 24 is controlled.
Feedback pressure oil-in 23, for receiving feedback pressure oil and entering oil pocket A21, now, electromagnetic valve 24 is in pass
Closed state, the feedback pressure of oil pocket A21 acts on outer regulation ring 26, when feedback pressure reaches setting value, adjusts the quilt of spring 27
Compression, outer regulation ring 26 is moved or swung, and reduces the eccentric throw between the inner ring of blade and outer ring, between blade and Internal and external cycle
The pumping cavity of formation variable quantity in lubricating oil pump operation process also accordingly reduces, and thus reduces oil pump capacity, so as to drop
The low engine oil pressure of lubricating oil pump.
When the feedback regulation insufficient pressure of oil pocket A21 is to meet requirement, actual engine oil pressure is still bigger than normal compared with demand pressure
When, electromagnetic valve 24 is opened, feedback pressure oil Jing electromagnetic valves 24 enter oil pocket B22, now the pressure in oil pocket A21 and oil pocket B22
Collective effect is in outer regulation ring 26, and it is identical that its pressure regulation mechanism and the pressure in oil pocket A21 act solely on outer regulation ring 26, so as to
Further reduce the engine oil pressure of lubricating oil pump.By the contrast of Fig. 6, Fig. 7 it can be seen that two grades of one kind that this utility model is provided can
Become lubricating oil pump and the engine assembly comprising it effectively reduces the actual pressure of machine oil so as to connect substantially with demand pressure
Closely.
