Abstract: A pressure fluid reservoir for supplying pressure fluid to a wheel slip regulating device that is accommodated in a vehicle has a hose membrane that can be partially emptied by suction. The degree of emptying is limited due to the installation of an inner support body that fluid can flow through. The radial expansion of the hose membrane is limited by an outer support element and by a porous casing encompassing the outer support element, which protects the pressure fluid reservoir from bursting in the event that the hose membrane is subjected to brake pressure. The inner support element, the outer support element, and the casing are flexible hoses and are connected in a pressure-tight fashion to tube line connections in such a way that the pressure fluid reservoir according to the invention is placed in the vehicle in the same way as a brake line.

Abstract: An accumulator piston for an automatic transmission. The piston comprises two components, the first and second being cup elements welded together with their closed ends in abutting relation. The lower cup includes a curled back portion with a radial flange having an axially extending bi-directional oil seal thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal thereon. The piston is spring-loaded and moves up and down in a bore and counterbore in response to fluid flow on either side of the piston to absorb shifting shocks.

Abstract: A hydraulic actuator for a hydraulically driven device has a hydraulic cylinder, a first piston slidably received for reciprocation within the cylinder and defining a hydraulic fluid chamber with the cylinder, a second piston slidably received for reciprocation within a cavity in an actuator rod connected to the first piston and defining a gas chamber on one side of the second piston and an accumulator chamber on the other side of the second piston. A passage formed in the first piston communicates the hydraulic chamber with the accumulator chamber and a pressure relief valve selectively permits hydraulic fluid flow through the passage from the hydraulic chamber to the accumulator chamber to limit the maximum pressure of the hydraulic fluid within the hydraulic chamber and the hydraulically driven device. Preferably, during normal operation of the actuator and the hydraulically driven device the pressure of the hydraulic fluid is less than that required to open the pressure relief valve. The pressure of the gas in the gas chamber and acting on the second piston forces hydraulic fluid in the accumulator chamber into the hydraulic fluid chamber through a check valve when the pressure in the accumulator chamber is greater than the pressure in the hydraulic fluid chamber to reset the accumulator.

Abstract: A toilet flushing system includes a fresh water feed, a fluid storage container connected to the fresh water feed, and a supply line coupled to the storage container and a toilet. The fluid storage container has a container casing and first and second separating diaphragms within the casing. The separating diaphragms define first, second and third partial chambers within the container casing for separately receiving gas and fresh water. The second partial chamber is defined between the separating diaphragms and receives gas. A valve in the fresh water feed and the supply line, closes the fresh water feed and the supply line. The valve is movable between a first switch position for filling the partial chamber with fresh water to be delivered to the toilet and a second switch position in which the third partial chamber simultaneously is filled with a medium.

Abstract: In the interior of the housing of an accumulator, a metallic bellows and a self-seal mechanism are arranged. The metallic bellows partitions the interior of the housing into a gas chamber and a liquid chamber. The self-seal mechanism includes an elastic seal member and a face which the elastic seal member opposes. When the bellows is compressed to the predetermined extent due to introduction of a compressed gas into the gas chamber, the elastic seal member is brought into contact with the face, thus closing a flow port. The elastic seal member has a slanted face, so that a wedge-shaped liquid guide gap is produced when the elastic seal member is in contact with the face. When, in this condition, the compressed liquid is introduced into the flow port, part of the liquid enters the liquid guide gap, thus permitting the seal member to easily separate from the face.

Abstract: A compensator for use with a hydraulic control valve connected to a source of high fluid pressure provides the functions of a low pressure return line accumulator and controllable check valve. A spring loaded piston (66) in a housing (64) has a working face exposed to fluid pressure downstream of the power control unit (10). A poppet valve (80) movable in a bore (78) on the axis of the piston is spring loaded against a seat (82) in the return line (40, 42) to interrupt flow between the downstream side of the power control unit (10) and the return side of the fluid pressure source. When normal return line pressure is sensed, the piston (66) moves against its spring (68) to permit the housing (64) to be substantially filled with fluid. Further increases in fluid pressure cause the piston (66) to contact and open the poppet (80) and permit flow to the return side (42) of the fluid pressure source. A working area (92) is formed on a part of the poppet (80) to the outside of the seat which area is exposed to the fluid pressure downstream of the power control unit (10). Should the piston (66) stick or seize in the housing (64), the fluid pressure acting against this working area (92) would increase to some value significantly above the normal pressure at which point it becomes sufficient to open the poppet (80), thus preventing the power control unit (10) from jamming or becoming hydraulically locked in position.

Abstract: A pressure transfer unit having a movable partition including a flexible bellows for separating an internal, controlled-pressure chamber from a reference-pressure chamber. A valve is provided for limiting the volume of liquid that can be injected into and received in the controlled-pressure chamber during filling or refilling thereof. A spring biases the partition to apply a predetermined force to the partition and to shut off fluid transfer in the event of bellows failure. The unit is arranged for simple and rapid assembly and disassembly.
