Dust impurity is avoided to enter in the valve opening of pressure regulator valve.
To achieve the above object, the technical solution of the utility model is: a kind of lubricating oil pump equipped with plunger type pressure regulator valve, packet
The pump housing is included, the inside of the pump housing is equipped with rotor chamber, and the bottom of the rotor chamber is equipped with oil suction slot and oil scupper, the pump housing
Outside is equipped with valve opening, is sequentially installed with plunger, spring and plug screw, the hole wall of the valve opening plunger section from inside to outside in the valve opening
It is equipped with oil inlet and drain tap, the valve opening spring section is adjacent with the oil suction slot of rotor chamber and communicates by a gas vent.
Preferably, the gas vent is provided with close to the position of plug screw.
Preferably, the oil inlet is communicated with oil scupper, and the drain tap is communicated with oil suction slot.
In one embodiment, the outer peripheral surface of the plunger is equipped with annular groove.
In one embodiment, the plunger is hollow cylindrical structure, the outer peripheral surface of the other end close to one end of spring
The outer peripheral surface of control chamber equipped with annular, the cylinder is equipped with annular groove.
Lubricating oil pump provided by the utility model, achieve it is below the utility model has the advantages that
1, since the position of the oil suction slot of pump housing rotor chamber is arranged in gas vent, thus completely cut off with outside air, avoid
Dust impurity enters in the valve opening of pressure regulator valve.
2, it is communicated by gas vent with the valve opening of pressure regulator valve due to oil suction slot, engine start moment, under the action of negative pressure,
Machine oil in oil suction slot will enter valve opening by gas vent, and oil film is formed between plunger and valve opening, make to play lubrication
With.
3, since gas vent is located on the pump housing, thus can direct casting and forming, save processing cost.
