Patent number: 4630800Abstract: A sealing arrangement, which can be inserted into a recess formed in a valve housing, to effectively provide a fluid pressure seal between at least one input chamber and one output chamber, and in which a slide piston is movably-disposed in the recess. The sealing arrangement includes a first gasket and a second gasket, which are disposed in coaxial relationship to one another, and which are concentric to the recess of the valve housing. The two gaskets are connected to one another by means of elastic annular connecting pieces. The connecting pieces of the two gaskets are located between a plurality of apertured retaining elements, which have a portion of the end surfaces of projections in contact with the connecting pieces. A plurality of rivet members pass through the apertured retaining elements and the connection pieces to hold them in the form of a sealing cartridge.Type: GrantFiled: February 12, 1986Date of Patent: December 23, 1986Assignee: WABCO Westinghouse Steuerungstechnik GmbH & Co.Inventors: Walter Brausfeld, Ernst-August Meyer

Patent number: 4627597Abstract: This invention relates to an activation apparatus for valves, specifically electromagnetically-activated multiway valves. The activation apparatus exhibits an activation element having a first stop and a second stop, which are arranged in facing-relation to one another, and to a housing projection formed by a graduated opening leading into the valve, so that a movement of the activation element, in the direction of its longitudinal axis, is limited or prevented. On the circumference of the activation element, there is a sealing element which is in sealed contact against the wall of the housing recess or graduated opening, which holds the activation element. The two stops and the sealing element are permanently connected with the activation element so as to form essentially a single-body construction.Type: GrantFiled: December 17, 1985Date of Patent: December 9, 1986Assignee: Wabco Westinghouse Steuerungstechnik GmbH & Co.Inventors: Walter Brausfeld, Helmut Gottling, Rudolf Moller, Peter Muller, Gerhard Scharnowski

Patent number: 4566196Abstract: A variable point position determining arrangement includes a housing having a stationary portion secured to a fixed member as, for example working cylinder, and an extendable portion secured to a member movable in relation to the fixed member, as for example piston rod. An elastic element, such as a tension spring, is connected between the stationary portion and an extendable portion of the housing. Such elastic element is stretched or relaxed an amount proportionate to the travel of the movable member. The displacement transducer having an actuator rod and a projecting pin connected to the elastic element at approximately a middle point, follows movement of the elastic element and outputs a distance signal which is a function of the movement of the actuator rod and elastic element. The distance signal can be fed to a control circuit to derive the position value of the movable member therefrom.Type: GrantFiled: September 4, 1984Date of Patent: January 28, 1986Assignee: WABCO Westinghouse Steuerungstechnik GmbH & Co.Inventors: Walter Brausfeld, Helmut Gottling, Rudolf Moller, Peter Muller, Gerhard Scharnowski

Patent number: 4531548Abstract: A force transmitting fluid actuator for use with a control device wherein an actuator member, movable within an actuator housing, actuates the control device due to the urging force of a plurality of pistons which can be selectively pressurized in unitary increments. The plurality of pistons are disposed within pressure chambers formed in the actuator housing in a symmetrical ring-shaped arrangement concentric to a single pressure chamber disposed on the vertical axis of the housing. A number of passageways interconnect the plurality of pressure chambers to form groupings of pressure chambers which act simultaneously in response to operation of a solenoid valve associated with each passageway. In addition to the symmetrical arrangement of the pressure chambers, the valve and passageway arrangement provide for a symmetric pressurization of the pressure chambers thereby resulting in a balanced force being exerted on the actuator.Type: GrantFiled: December 2, 1983Date of Patent: July 30, 1985Assignee: WABCO Steuerungstechnik GmbHInventors: Helmut Gottling, Walter Brausfeld

Patent number: 4475572Abstract: A multiway valve device in which a handle-operated ball member is operatively disposed in a spherical cavity to which a plurality of passages is connected. The ball member is arranged with a single seal ring that encloses a recessed area at one end of the ball that is sized to establish fluid pressure communication between a supply passage and one or the other of a pair of delivery passages depending upon the handle being located in an extreme right- or left-hand position. A vent passage opens into the spherical cavity in the area of the ball opposite the recessed area enclosed by the seal ring to exhaust pressure from whichever delivery passage is cut off from the supply passage. The spherical cavity lies partly in the body of the valve device and partly in a cover portion, which when secured to the body, rotatably supports the ball member.Type: GrantFiled: November 9, 1981Date of Patent: October 9, 1984Assignee: WABCO Steuerungstechnik GmbHInventors: Walter Brausfeld, Helmut Gottling

Patent number: 4401293Abstract: An arrangement wherein fluid pressure passageways opening into inner chambers of a cylindrical housing of a valve device, are formed between abutting faces of two axially aligned cylindrical portions comprising the housing. The opening or passageway between the abutting faces is formed by complementarily engaging saw-like teeth formed around the annular abutting faces of the two housing portions. This arrangement provides a smoother surface over which the sealing gasket on a valve member must ride, thus resulting in less wear and tear on the gasket.Type: GrantFiled: September 24, 1981Date of Patent: August 30, 1983Assignee: WABCO Steuerungstechnik GmbHInventors: Gerhard Rodewald, Detlef Opel, Walter Brausfeld, Helmut Gottling, Hans-Friedrich Meyer, Rudolf Moller
