Abstract

A fluid-operated actuation device (1), comprising at least one supporting body (2), which is associated with at least one substantially through receptacle (3) provided with first and second mutually opposite open ends, at least one preassembled push rod assembly (4), which is inserted so that it can slide along the receptacle (3) at the first end, means (5) for actuating the sliding of the push rod assembly (4) along the receptacle (3) at least toward the second end, and at least one preassembled reduction valve assembly (6), which is associated with the supporting body (2) at the second end and comprises a valve body (7) provided with at least one intake port (7a) for a working fluid at an operating pressure, with at least one port (7b) for the output of the working fluid at a reduced pressure toward a user device, and with at least one discharge port (7c) for the fluid and at least one flow control element (8), which is accommodated within the valve body, can move alternately between an inactive configuration and an active configuration, is interposed between the ports and cooperates with the push rod assembly, the flow control element (8) being adapted to close at least partially the intake port (7a) and to connect the output and discharge ports in the inactive configuration and to close at least partially the discharge port (7c) and connect the intake (7a) and output ports (7b) in the active configuration.
