Abstract
The utility model discloses an oil pump controller which comprises a pump base, an actuator and an oil pump. The actuator and the oil pump are installed on the pump base. The actuator comprises a motor and an actuating part. A rotating shaft of the motor is connected with the actuating part and can drive the actuating part to swing. The actuating part is provided with a torsional spring used for returning the actuating part after the actuating part swings. The actuating part is connected with an oil amount control pull rod of the oil pump and is perpendicular to the oil amount control pull rod. Under driving of the motor, the actuating part swings to pull the oil amount control pull rod to move left and right so that the oil outlet amount of the oil pump can be changed through the oil amount control pull rod. The oil pump controller has the advantages that the torsional spring is adopted as the spring used for returning, spring elasticity is uniform and convenient to control, and therefore the requirement for driving power of the actuator is effectively lowered; the oil amount control pull rod is arranged on the side of the actuator, the actuating part is arranged perpendicular to the oil amount control pull rod, influence on motion of the pull rod from lateral force is little, and therefore clamping stagnation of the pull rod can be remarkably reduced.

Wherein, described motor is located at the upside of pump seat, and pump seat below is stretched out in the rotating shaft of motor, and described rotating shaft connects a U-shaped link, and described U-shaped link connects described actuator by its crotch.
Wherein, described actuator also comprises pull bar and bearing, the middle part of described pull bar is rotatably mounted on described bearing by a Cylindrical object, bearing is fixed on described pump seat below, described torsion spring is located at this Cylindrical object outside and is supported between pull bar and bearing, and one end of pull bar is provided with a vertical vertical rod, and described vertical rod is connected with the crotch of described U-shaped link, the other end of pull bar has U-shaped opening, and described U-shaped opening is perpendicular to described fuel-flow control pull bar and be connected with it.
Wherein, described fuel-flow control pull bar is cylindrical, and by being connected with described U-shaped opening perpendicular to its surperficial round end projection, this round end projection can be slided in U-shaped opening.
Wherein, described fuel-flow control pull bar is located on two supporting bases of described pump seat below, and fuel-flow control pull bar can slide in described supporting base.
The beneficial effects of the utility model are: the spring for return adopts torsion spring, and spring force is more even, and it is convenient to control, and effectively reduce the requirement to actuator driven power; Fuel-flow control pull bar is arranged in final controlling element side, and actuator arranges perpendicular to oil mass control pull bar, and lateral force is less to the motion effects of pull bar, can significantly reduce pull bar catching phenomenon.
