Patent number: 10493971Abstract: In an electric motor-pump assembly, two working diaphragms, each delimiting a working chamber, are cyclically driven by a crank drive via connecting rods. The crank drive includes eccentrics for each connecting rod, which are placed on an axial bearing journal in the extension of an output shaft of an electric motor. In order to ensure a rotationally fixed connection between the eccentrics and the bearing journal to be produced and in order to ensure an angularly precise position of the two eccentrics, each of the eccentrics is connected to the bearing journal by a positively locking engagement.Type: GrantFiled: August 17, 2015Date of Patent: December 3, 2019Assignee: Continental Teves AG & Co. oHGInventors: Heinrich Kreh, Michael Jürging, Marcel Niepenberg, Jose Gonzalez, Hans-Michael Koppel, Manfred Rüffer

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
