The disengagement command signal initiates disengagement of the motor module from the output ram.

The hydraulic output device (10) comprises a hydraulic cylinder (11) with an output shaft (12).

A low pressure hydraulic cylinder (4) has an inlet hole and an outlet hole.

The ram (33) is mounted in the housing (91, 107) for vertical movement through an opening in the top of the housing (91, 107), allowing the ram (33) to move between a stored position and a raised position.

A pneumatic cylinder designed to convert compressed air into mechanical output is disclosed.

The ram is hollow and can be driven between extended and retracted positions.

The water conduit system (6) is connected to the hydraulic cylinder (21) of the outlet valve arrangement (20).

The disengagement command signal initiates disengagement of the motor module from the output ram.

An actuator is fixedly coupled to the seat cushion and operatively coupled to the output shaft for rotatably driving the output shaft.

The integrated breakaway cylinder is constructed from a first stage cylinder and a second stage cylinder.

Two oil outlets are connected to the chamber with pistons of the power cylinder separately by the pipeline.

The ram includes a ram lug spaced from the central axis.

A hydraulic cylinder (2) having a piston (1) and a linearly extending output shaft (15) controlled by a rotary spool valve (6).

A bearing (86) supports a ram (70) within the housing (72) for extension and retraction.

The cylinder includes a cylinder body and a piston apparatus.
