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: 8926293Abstract: Disclosed is a motor-pump assembly (1) for a brake actuating device of a motor vehicle brake system with a pneumatic brake booster. An electric motor (3) drives a double diaphragm pump (2) with two working diaphragms (4) which are located opposite one another. Air expelled from the working spaces (7) is directed into an interior space (22) surrounding a crank drive (8) of the pump housing (5). An air outlet unit (13) permits low-noise expulsion of the air from the interior space 22 by deflecting the air. In order to make available a low-noise, cost-reduced motor-pump assembly the eccentrics (9) each have an unbalance weight (25) integrally molded onto the eccentric (9).Type: GrantFiled: December 15, 2009Date of Patent: January 6, 2015Assignee: Continental Teves AG & Co.

Patent number: 8702180Abstract: A motor and pump assembly for providing pressure to a brake actuating device of a motor vehicle brake system is described herein. The assembly comprises an electric motor and a double diaphragm pump. The pump includes a pump housing, two opposed working diaphragms, and crank drives each being coupled between the electric motor and a respective diaphragm for moving the diaphragm. A working chamber is defined between the pump housing and a working chamber cover. Each working chamber including an inlet channel, an inlet valve associated with the inlet channel, an outlet channel, and an outlet valve associated with the outlet channel, wherein the outlet channels are defined in the covers of the working chamber and in the pump housing to direct air displaced from the working chambers into an inside space of the pump housing. An air outlet unit is provided for exhausting the air from the inside space.Type: GrantFiled: January 30, 2007Date of Patent: April 22, 2014Assignee: Continental Teves AG & Co. oHGInventors: Manfred Rüffer, Wolfgang Ritter, Karlheinz Seitz, Stefan Drumm, Jose Gonzalez, Michael Jürging, Daniela Gude, Oliver Volkering, Jürgen Schonlau

Patent number: 8585372Abstract: A motor/pump assembly for a motor vehicle brake system including a pump and a motor driving the pump, the pump having opposite working diaphragms which are, in each case, mounted between a pump casing and a cover and thereby delimit a space and which can be moved by a crank drive, the space being assigned, in each case, an inlet duct with an inlet valve and an outlet duct with an outlet valve. The outlet ducts are arranged in the covers and in the pump casing such that air displaced out of the spaces is conducted into an inner space surrounding the crank drive of the pump casing and that an air outlet unit be provided, which allows a low-noise blow-out of the air from the inner space as a result of the deflection of the air.Type: GrantFiled: September 8, 2008Date of Patent: November 19, 2013Assignee: Continental Teves AG & Co. oHGInventors: Jens Bacher, Lazar Milisic, Wolfgang Ritter, Karlheinz Seitz, Manfred Rüffer, Jose Gonzalez, Thomas Stahl, Michael Jürging, Yuejun Qian
