Abstract

The invention discloses a vane-type hydraulic machine. The vane-type hydraulic machine comprises an oil inlet side plate, an oil outlet side plate, a rotor, a stator and a vane which is arranged inside a rotor groove, wherein the vane and the bottom of the rotor groove form a bottom cavity, a high-pressure port and a lower-pressure port are respectively formed on the oil inlet side plate and the oil outlet side plate, a fluid passageway is arranged on the vane, the end part of the vane is provided with a vane top groove which is communicated with the fluid passageway, the top of the vane and the contact line of the inner surface of the stator are respectively arranged on the two sides of the vane top groove, fluid channels corresponding to the fluid passageway are respectively arranged on the oil outlet side plate and the oil inlet side plate, and the fluid passageway, the vane top groove and the fluid channel form a vane control chamber. The vane-type hydraulic machine is simple and convenient to machine and has low cost; the accuracy of the vane-type hydraulic machine is ensured; the reliable contact between the vane and the inner surface of the stator is ensured; the abrasion is also controlled; the working pressure is increased; the product performance is improved; and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic machinery, in particular to a blade type hydraulic mechanism. Background technique [0002] The vane hydraulic pump or motor is small in size, small in moment of inertia, and sensitive in action. It is suitable for occasions with high commutation frequency, but the leakage is large and unstable at low speed. Therefore, vane hydraulic motors are generally used in occasions with high speed, small torque and sensitive action requirements. For traditional hydraulic pumps or motors, in order to ensure that the vane hydraulic motor can start normally after the pressure oil is introduced, the top of the vane must be in close contact with the inner surface of the stator to ensure a good seal, so pre-tension springs are provided at the root of the vane , but in this traditional hydraulic motor and pump, since the blade root is provided with a preload spring, the top of the blade is always in close conta...
