Abstract

The present invention designs a control arm for an injection valve, which includes an arm body and bushes arranged at both ends of the arm body. The bushing includes an inner liner, a rubber ring and an outer liner. The rubber ring is arranged on Between the inner liner and the outer liner; the inside of the inner liner is provided with a plurality of hollow cavities uniformly distributed along the cross section of the inner liner, and the upper and lower ends of the cavity are connected with an air inlet pipe, The air inlet pipe is connected to the outside of the lining pipe; the upper and lower ends of the cavity are connected to one end of an air delivery pipe, and the other end of the air delivery pipe extends to the outside of the inner lining pipe and is transversely connected to the inner lining pipe. On the pipe, the rubber ring and the outer liner; the air pipe is provided with a plurality of exhaust holes. The device can output the gas in the cavity to the annulus of the bushing through the exhaust hole when the cavity provided inside is squeezed, so as to clean the annulus of the bushing.

Description

technical field [0001] The invention relates to a control arm, in particular to a control arm for an injection valve. Background technique [0002] The control arm, also known as the swing arm, acts as a guiding and force transmitting element. In the dispensing device, the control arm is used as a device for power transmission of the injection valve, and its main function is to control the movement of the injection valve according to a certain trajectory. The ball valve is an element used to connect the control arm to the injection valve. [0003] The control arm with the bushing installed may be corroded by the outside for a long time due to the use of rubber parts in the bushing, which will reduce the service life of the bushing. [0004] In view of the above-mentioned defects, the designer actively researches and innovates in order to create a control arm for injection valves with a new structure that can automatically clean the surface of the bushing, so that it has mo...
