Abstract
A fluid operated actuator (100) is provided. The fluid operated actuator (100) includes a cylinder body (101) and a piston (102) movable within the cylinder body (101). The piston (102) defines a first chamber (105) and a second chamber (106). The fluid operated actuator (100) can include a fluid inlet (107) formed in the first chamber (105). A bleed port (110) can be formed to provide fluid communication between the first chamber (105) and the second chamber (106).
Claims19
A fluid operated actuator (100), comprising:
- a cylinder body (101);
- a piston (102) movable within the cylinder body (101) between a first position and a second position, the piston (102) defining a first chamber (105) and a second chamber (106);
- a fluid inlet (107) formed in the first chamber (105);
- and
- a bleed port (110) providing fluid communication between the first chamber (105) and the second chamber (106).
A method for controlling a fluid operated actuator including a piston movable within a cylinder and defining a first chamber and a second chamber, an inlet formed in the first chamber, and a bleed port providing fluid communication between the first chamber and the second chamber, the method comprising the steps of:
- pressurizing the first chamber through the inlet;
- actuating the piston away from a first position towards a second position;
- and
- bleeding at least some of the pressure in the first chamber into the second chamber through the bleed port as the piston is actuated towards the second position.
