Question

in hydraulic motors or Rotary Actuators The device which provides also torque and pressure?​

Answer 1

Answer:

Hydraulic rotary actuators are typically utilized for applications requiring high torques. Common design configurations for hydraulic rotary actuators include piston type, vane type, or gear type. In piston-type actuators, pressurized hydraulic fluid is used to displace a piston and generate rotational motion. An example of a piston-type actuator is a swash plate motor. In a swash plate motor, pressurized oil is used to push a piston back and forth and generate rotation of a swash plate. The swash plate is connected to a shaft which rotates as the plate rotates. In vane-type actuators, the operating principle is similar to that of a pneumatic rotary actuator.
