Title: Piston/cylinder unit
Inventor: LUHMER HORST DR
IPC: F15B15/04
Filed: 1986-05-10
Abstract: The invention relates to a piston/cylinder unit with a piston rod which is linked to the piston by means of a spherical joint. Since ball heads and ball sockets can only be produced on special machines and in addition have a comparatively large diameter, and joint heads as commercially available components considerably increase the installation length, a solution is aimed at with which short overall lengths at high buckling resistance can be realised with commercially available components by the modular construction principle. The solution consists of a piston which has an undercut hollow space which is partly delimited by a web on which bearing surfaces for axial self-aligning plain bearings having the same centre point are provided. Axial self-aligning plain bearing and web are penetrated by a pin-like extension of the piston rod and are braced against one another by fastening means.

Title: Non-return valve with an integrated pressure-regulating piston
Inventor: MICHAELIS LOTHAR
IPC: F15B13/01
Filed: 1987-07-17
Abstract: A non-return valve with an integrated pressure-regulating piston, which has a free passage with a non-return valve function in one direction of flow, has in a valve slide acting as a non-return valve a pilot-controlled pressure-regulating piston 5 which is effective in the other direction of flow. The non-return valve action is effective in the direction of flow from connection 2 to connection 3 while the pilot-controlled pressure-regulating piston 5 is effective in the direction of flow from connection 3 to 2. Mounted in a housing 1 with a bore 27 and 28 is a valve slide 4 which has a shoulder 29 that controls the two annular notches 24 and 25. In the appropriate position, the spring space 61 of the pressure-regulating piston 5 mounted in the bore 31 of the valve slide 4 is connected via hole 60, pressure space 59, radial holes 30, annular notch 24 and connecting hole 20 to control connection 21 and the piston can be controlled by means of a pressure-regulating valve.   The compression spring 10 presses the valve slide 4 against the seat edge 33, the annular surface formed by hole 27 and 28 displacing the valve slide 4 counter to the compression spring 10 during the non-return valve action. The pressure-regulating piston 5 is pressed onto the conical seat 35 by the compression spring 7 and opened in a known manner by pilot-controlled pressure valves as soon as a pressure difference arises between the pressure space at the conical seat 35 and the spring space 61, i.e. as soon as a flow of control oil ...

Patent DE-3729222-A1 (DE)
Inventor: FRIEDERICHS OTTO DIPL ING
IPC: F15B13/043
Filed: 1987-09-02
Abstract: 2.1. Known electromagnetically actuated valve devices for controlling the connection between a hydraulic fluid source and a consumer system (inlet valve) or for controlling the pressure relief of a consumer system, have the disadvantage that they have only limited suitability for finely adjusting the consumer pressure, since they operate with a relatively large pressure drop between the inlet pressure and the consumer pressure with a large flow rate, which leads to the consumer pressure overshooting and undershooting. Other known valve devices of this type have a consumer-pressure-dependent response and therefore likewise have only limited suitability for the described purpose. The invention proposes solutions which permit fine adjustment of the consumer pressure in each consumer pressure range. 
<??>2.2. The invention proposes that the opening cross-section of an initial control valve, known per se, be made continuously adjustable by means of an actuating magnet, likewise known per se, having a flow- dependent movement characteristic; it is additionally proposed that the opening cross-section of a main valve, known per se, also be made continuously adjustable as a function of the flow, by coupling an initial control valve member in a fixed manner to a main valve member. 
<??>2.3. An advantageous area of application of the invention is for electrically controlled and/or electrically regulated motor vehicle brake systems (for example anti-lock braking systems).

Patent DE-3801459-A1 (DE)
Title: Double universal joint
Inventor: BERGER HEINRICH
IPC: F16D3/32
Filed: 1988-01-20
Abstract: A surround (2) in the form of a ring (1) or a bell for each yoke (3) of the double universal joint provides an angle-limiting stop for each of the two universal joints. If this stop is reached by one universal joint as the universally-jointed shaft bends, the said joint continues to operate in a constant, uniform manner without deviation. This provides smooth running, without friction and wear at the ring surfaces. It may also be advantageous for one universal joint of the double universal joint to be prevented by pressure or tension from springs (7) or rubber rings, optionally in conjunction with a surrounding slidable tube (9) with sliding slots (10), from bending until the other universal joint has bent as far as the angle-limiting stop. <IMAGE>
