Patent number: 9828981Abstract: The invention relates to a pump unit that can be driven by an electric motor, in particular for providing vacuum for a pneumatic brake booster, including a pump housing that can be closed by a working-chamber cover and at least one elastic displacement element, wherein a working chamber is bounded between the displacement element and the working-chamber cover and wherein inlet valves and outlet valves and inlet channels and outlet channels associated with the valves are associated with the working chamber. According to the invention, in order to reduce noise emissions, devices for reducing a contact surface between the working-chamber cover and the pump housing are provided.Type: GrantFiled: February 1, 2013Date of Patent: November 28, 2017Assignee: Continental Teves AG & Co. oHGInventors: Stephan Krebs, Jens Bacher, Heinrich Kreh, Lazar Milisic, Michael Jürging, Marcel Niepenberg, Jose Gonzalez, Karlheinz Seitz, Hans-Michael Koppel, Falk Petzold, Rolf Fellinger, Stefan Imhof, Thomas Oeffner, Paul Wiebe, Manfred Rüffer

Patent number: 9784264Abstract: A pump assembly for supplying negative pressure to a pneumatic brake booster, wherein the pump assembly has at least two elastic displacement elements which are moved by connecting rods, the connecting rods each being rotatably mounted on an eccentric element. The eccentric element has a bearing seat element and a force element. At least two eccentric elements are secured next to each other on a drive shaft that rotates about an axis of rotation and an interlocking anti-rotation device is provided that determines a defined angular position of the eccentric elements relative to each other about the axis of rotation. In order to improve the ease of assembly and simplify the manufacturability, the anti-rotation device is designed as shaped elements of the bearing seat element in such a way that they engage in each other in an interlocking manner when the eccentric elements are in a defined angular position relative to each other.Type: GrantFiled: April 25, 2014Date of Patent: October 10, 2017Assignee: Continental Teves AG & Co. oHGInventors: Stephan Krebs, Jens Bacher, Heinrich Kreh, Lazar Milisic, Michael Jürging, Marcel Niepenberg, Jose Gonzalez, Karlheinz Seitz, Hans-Michael Koppel, Falk Petzold, Rolf Fellinger, Thomas Oeffner, Paul Wiebe, Stefan Imhof, Manfred Rüffer

Patent number: 8297264Abstract: A valve for the control of a gas stream is provided with a valve housing enclosing a valve chamber. At least one pressure-sided inlet and at least one suction-sided outlet is provided with a valve opening between them to link them. An elastically movable control membrane is arranged at the valve housing which reduces or increases the flow cross section in the area of the at least one valve opening and/or opens or closes the at least one valve opening. A first device exerts a first further force on the control membrane in such a way that with an increasing pressure difference the further force exerted by the first device on the control membrane in opposite direction to the closure direction of the valve increases.Type: GrantFiled: June 16, 2009Date of Patent: October 30, 2012Assignee: Reinz-Dichtungs-GmbHInventors: Carl Stefan Imhof, Carl Imhof, legal representative, Marlies Imhof, legal representative
