    • A hydropneumatic actuator applicable to linear actuations, comprising arrangements the purpose of which is to create internally and regeneratively a hydraulic pressure from the movement of the movable parts. These arrangements make it possible to slow the movement by finely adjusting its speed when this is required for the usage. The actuator comprises an annular pneumatic piston (Pp) provided with a movable tube (21) crimped in the internal bore of the piston, the pneumatic piston (Pp) being able to be moved in an external cylinder (Cy) under the effect of a pressure differential applied to the exterior by pneumatic connections (X1, X2). The actuator is further provided with a coaxial hydraulic piston (Ph) provided with a rod (10) sliding in a fixed coaxial lining (19, 20) separating the two pistons which remain attached to each other by a mechanical connection (1 1) between the end of the rod (10) of the hydraulic piston and the end of the movable tube (21). The actuator further includes electrical or pneumatic control valves, adjustable chokes, non-return valves, and an oil reservoir (15) kept under pressure by a spring (16) adjustable by a screw (1). The reservoir can be connected through valves, adjustable chokes and non-return valves to both sides of the hydraulic piston (Ph).

    • A pneumatic device (10) comprises a piston (12) moveable along a cylinder (10). The piston has opposite ends (18, 26) defining a space (30) therebetween. The space is divided into two chambers (30a, 30b) by a housing (40) fixed relative to the cylinder and having a fluid flow control passageway (42) therethrough. The space (30) is filled with fluid, such as oil. The piston (12) is arranged such that movement thereof against a spring (16) causes the fluid to be displaced from one chamber (30a) of the space (30) to the other chamber (30b) through the passageway (42). The spring (16) is arranged to apply a return force to the piston (12) and the rate of return of the piston (12) is controlled by the return flow of fluid through the passageway (42). A pneumatic system (100) includes a device (10) connected between first and second members (58, 58a) of a building, such as a door and door frame. The pneumatic system comprises a source of compressed gas (C) for operating the device (10) to enable the device (10) to move the first member (58) relative to the second member (58a), i.e. to open and close the door. A switching device (72) controls the supply of compressed gas to the device (10).

    • A fluid-power cylinder comprising a power cylinder member (11) and a power piston member (12) reciprocable therein between end positions includes a device for cushioning the relative movements of the power piston member and the power cylinder member adjacent the end positions. The cushioning device comprises a cushioning cylinder (13) movable together with the power piston member (12) and a cushioning piston (14) which is stationary with respect to the power cylinder member (11) and which is receivable and axially movable in the cushioning cylinder to define a cushioning cylinder compartment (31A, 31B) having a restricted discharge passage (37/38, 40/41). A seal (36A, 36B) on the cushioning piston (14) acts as a one-way valve to prevent flow of cushioning fluid between the cushioning piston (14) and the cushioning cylinder (13) when the cushioning piston moves inwardly in the cushioning cylinder compartment (31A, 31B) and thereby reduces the volume of the compartment, but allows substantially unrestricted fluid flow when the cushioning piston moves outwardly.
