Title: Device for generating a fluid pressure
Inventor: ENGFER ORTWIN
IPC: F16H48/30
Filed: 1983-04-26
Abstract: A device for generating an electrically controlled hydraulic pressure is proposed which has a piston (13) which is displaceable in a cylinder (11) and is actuated by a pressure-intensifier piston (16) formed in one piece with it. The pressure-intensifier piston (16) can be acted upon by vacuum in a pressure chamber (17) against the action of a restoring spring (20). The vacuum is controlled by means of an electrically operable vacuum solenoid valve (10). The bottom part of the pressure chamber (17), which bottom part communicates with the cylinder (11) in the initial position of the piston (13) for the follow-up of the fluid, serves as a fluid supply (12). The pressure generator is simple, inexpensive and functionally reliable. It is of small dimensions and enables space to be effectively utilised (Fig. 1). <IMAGE>

Patent DE-3333141-A1 (DE)
Inventor: SIMON GEORG
IPC: F16J13/02
Filed: 1983-09-14
Abstract: The device is used for a rapid moving connection of two construction elements (1, 2). The connection between the two elements is obtained by means of an expandable cone (15) of which the outer conical surface grips to an inner surface of a conical collet (20) forming a passive clamping element, the clamping action being obtained by a continuous displacement of a cone (14) opening the expandable cone (15) against a resistance. The hydraulic clamping device may generate clamping forces which may reach several tens of one thousand N. The advantage of the present invention lays in the fact that the two elements may be made integral by a single rectilinear motion without rotations or other lateral displacements after simply superposing said elements. Furthermore, a good centering effect is obtained, which is not the case with conventional clamping devices.

Title: Non-return valve
Inventor: KOLLMANN DIETER DIPL ING
IPC: F16K47/02
Filed: 1984-07-23
Abstract: The invention relates to a non-return valve (2) for pipe conduits (3,4) filled with liquid. The non-return valves are intended to close off the connected pipe conduits automatically when the direction of flow is reversed. In the case of rapid flows of liquid or high pressure differences, significant pressure shocks or "water hammer", endangering the pipe conduit, can occur. To avoid such pressure shocks, the invention provides that, in a valve with a damping piston (10) displaceable in a separate damping cylinder (6), at least one pressure-compensating channel (13 to 16, 20 to 23) is let into the wall of the damping cylinder, connecting the volumes above and below the damping piston and providing the damping piston with at least one further outflow channel (19, 24, 25), of relatively small cross-section, connecting the subspaces on both sides of the damping piston in the range of the closed position of the valve. The invention furthermore provides that the outflow channel (24, 25) be a narrow continuation of an opening (20, 22) in the wall of the damping cylinder, the said continuation extending to below the bottom edge of the damping piston in the closed position of the valve. A non-return valve according to the invention is suitable, in particular, for use in power stations. <IMAGE>
