Fluidic actuator for control of gearbox parts comprises hollow cylinder and piston which delimits fluidic chamber and passage through which fluid is displaced by piston

摘要

The fluidic actuator comprises a hollow cylinder (3) containing a piston (13). A fluidic chamber (25) is delimited by the piston, the cylinder bore (5) and one end (4) of the cylinder. A passage (9) communicates with the chamber so that a displacement of the piston causes a displacement of the fluid in the passage. An additional fluid storage chamber (31) inside the cylinder is in communication with the fluidic chamber. An additional piston (26) located in the cylinder is returned to a rest position by a return spring (33).
