the present invention relates to a hydraulic and pneumatic vane motor, and is characterized by that in the radial direction of rotor, relative to the rotor, its vane can implement reciprocating motion, and the moving distance of whole vane is the maximum gap between rotor and cylinder body.

In the existing hydraulic and pneumatic vane motor, a rotor is provided with vane grooves, a spring needs to be installed or hydraulic and pneumatic channels need to be designed, and the rotor is relatively complex in structure and heavy; the rotor of the invention has the advantages of relatively simple structure, simple manufacturing process, relatively low cost, easy maintenance and light weight.

The existing hydraulic and pneumatic vane motor has relatively simple vane design, the radial movement of the vane is powered by a spring or liquid (gas) pressure, and when the motor works, the vane movement may generate hysteresis, which causes liquid (gas) leakage and reduces the motor efficiency; the vanes provide a reverse force inwards from the inner wall of the cylinder body, a certain friction force can be generated, the direction of the reverse force is not radial, but forms a certain angle with the vanes, and the reverse force provides a radial force for the vanes, and simultaneously provides resistance for the movement of the vanes and the rotor, so that the motor efficiency is reduced; the invention designs the blade guide rail, the guide rail fitting piece, the blade roller or the blade rolling shaft which are matched, so that the motion of the blade is smoother, the reliability is higher, the sealing performance is better, the friction force of the inner wall of the cylinder body is reduced, the reverse resistance of the machine is avoided, and the working efficiency of the motor is greatly improved; although the blade of the invention has relatively complex design, compared with the complexity and the difficulty of the manufacturing process of the traditional blade motor rotor, the blade is still simple and easy, and the manufacturing cost is also reduced to a certain extent.

The conventional vane type hydraulic (pneumatic) motor has a small capacity of a hydraulic (pneumatic) chamber formed between vanes due to the restriction of a vane structure, and the flow rate ratio and the power ratio of the motor are greatly limited. According to the vane motor, the capacity of the liquid (gas) chamber formed between the vanes is large, and the power of the motor can be greatly improved under the condition that the volumes of the motors are similar.

Compared with the traditional vane motor, the vane motor optimizes the liquid (gas) inlet and outlet, and makes qualitative design on the opening position and the ending position of the inlet and outlet, thereby being beneficial to fully utilizing the liquid (gas) to generate torque and power and improving the efficiency of the vane motor.

The invention comprises a plurality of chambers for working, more than two chambers are always in a liquid (gas) inlet working state, and a blocking state does not exist; the blade works reliably under the action of the blade guide rail; the blades are paired and arranged in an axisymmetric manner, and the whole motor is basically in a shaft balance state, so that the vibration and the noise of the blade motor can be well controlled.

The invention can directly generate rotary power by utilizing pressurized liquid (water and oil) or gas (including high-pressure fuel gas and high-pressure steam generated by fuel oil and fuel gas), and has higher energy conversion efficiency. The device can be widely used for generating electricity or driving other mechanical devices, and can also be used as a liquid and air pump base structure.

Compared with the hydraulic and pneumatic motors which are widely applied at present, the invention has the advantages of simple structure, reliable work, convenient maintenance, simple manufacturing and mounting process and low manufacturing cost, and has the obvious characteristics of high power ratio and high energy conversion efficiency.
