Intracavitary hole coincide, and a U-type groove is provided with the end face of the rotor, is provided with boss on the blade, the U-shaped groove with
Boss on blade is engaged, and the end face of the rotor is equipped with two fuel feed holes for being symmetrical with U-shaped groove, and described in two
Fuel feed hole is connected with the oil inlet on the pump housing.
Preferably, the boss both sides on the blade end face are equipped with two symmetrical U-type grooves.
Preferably, semi-circular groove is offered on the end face of the U-shaped groove, two symmetrical fuel feed holes are positioned at U-shaped
On the end face of groove and the U-shaped groove of face both sides, the semi-circular groove connects with the oil outlet on the pump housing.
The utility model proposes a kind of single rotary vane type grease pump, beneficial effect is：Oil pump has the function of double rotational directions,
I.e. no matter the output rotation direction of gearbox is rotating forward or reversion, and the oil outlet of oil pump can normally export lubricating oil, and oil pump is low
Fast performance is good, the output lubricating oil that grease pump can be stablized under 20rpm rotating speeds, and simple in structure, easy to process.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
With reference to Fig. 1-8, a kind of list rotary vane type grease pump, including the pump housing 1, rotor 2, blade 3 and pressing plate 4, sets in the pump housing 1
The circular pump chamber 9 of two decentractions is equipped with, rotor 2, the cylindrical and circle of rotor 2 are set in the circular pump chamber 9 of 1 bottom of the pump housing
The endoporus of shape pump chamber 9 coincide, and is equipped with blade 3 in the off-centre operation pump chamber 10 at the top of the pump housing 1, the cylindrical and pump housing 1 of blade 3 pushes up
10 endoporus of off-centre operation pump chamber in portion coincide, and a U-type groove 7 is provided with the end face of rotor 2, boss 11, U is provided with blade 3
Type groove 7 is engaged with the boss 11 on blade 3, and the end face of rotor 2 is equipped with two fuel feed holes 5 for being symmetrical with U-shaped groove 7,
And two fuel feed holes 5 are connected with the oil inlet on the pump housing 1,7 end face of U-shaped groove on rotor 2 is equipped with a semi-circular groove
8。
11 both sides of boss on 3 end face of blade are equipped with two symmetrical U-type grooves 6, are opened up on the end face of U-shaped groove 7
