Patent number: 11148650Abstract: A pneumatic brake booster having a booster housing. The booster housing has at least two thin-walled shell elements and an elastomer sealing element. The sealing element has a sealing bead, which is of encircling form radially at the outside, and at least one rolling diaphragm portion which adjoins the sealing bead. The sealing bead is sealingly clamped in a clamping space between the shell elements. The clamping space is formed by walls which are generated in the shell elements by deformation, its radial inner wall formed by a tubular, axially forwardly extending projection, which is folded at its front edge, of the second shell element. It is proposed that a bead-side rear wall of the clamping space is formed by an encircling, radially outwardly projecting collar which is formed on the second shell element.Type: GrantFiled: November 17, 2017Date of Patent: October 19, 2021Inventors: Jürgen Faller, Ralf Jakobi

Publication number: 20070266816Abstract: The present invention relates to an adjustable pedal device including at least two pedals whose initial position is variable. A pedal device is disclosed wherein a control member is rotatably articulated at the pedal lever for the brake, while the lever is rotatable about a third axis. It is disadvantageous in the prior art construction that a second pedal, particularly an accelerator pedal, cannot be simultaneously adjusted according to said principle because the forces acting upon the individual pedals are not effective in the same direction. The invention relates to a pedal device which has a simple design and in which the initial position of the mentioned two pedals can be adjusted in a substantially uniform manner, the two pedals being mounted in a twistable mounting support while being rotated about axes that are offset one relative to the other.Type: ApplicationFiled: June 21, 2007Publication date: November 22, 2007Inventors: Ralf Jakobi, Horst Kramer, Michael Haber, Jurgen Schonlau, Holger Kranlich, Thomas Sellinger

Patent number: 7152406Abstract: The invention relates to a master cylinder with a pressure chamber formed in a housing of the master cylinder and a reservoir bore for accommodating a pressure fluid reservoir, a valve with a closing element being provided which due to a pressure difference prevailing between the pressure chamber and the pressure fluid reservoir can be moved into an opening position or a closing position, the valve in its opening position allowing a pressure fluid flow from the pressure fluid reservoir into the pressure chamber and throttling or preventing, in its closing position, a pressure fluid flow from the pressure chamber into the pressure fluid reservoir. Means are provided which maintain the closing body in its opening position when it is acted upon by a closing pressure difference during vacuum filling of the brake system.Type: GrantFiled: July 30, 2003Date of Patent: December 26, 2006Assignee: Continental Teves AG & Co. oHGInventors: Holger von Hayn, Jürgen Schonlau, Manfred Rüffer, Wolfgang Ritter, Milan Klimes, Torsten Queisser, Ralf Jakobi, Michael Vogt, Dieter Merkel, Bernhard Hammes, Hans-Jörg Feigel, Jose Gonzalez, Stephan Krebs, Oliver Kugland, Thomas Sellinger, Guido Schell

Patent number: 6886333Abstract: The present invention relates to a position indicator for displaying the position of a piston within a cylinder as part of a piston-and-cylinder assembly in a brake system. The provision of a Hall element for a hydraulic generating cylinder is known in the art, with the Hall sensor mounted on the cylinder and a ring magnet mounted on the piston. An object of the invention is to describe a position indicator for a brake system, which has a simple construction and is able to provide signals relating to the position of the brake pedal relatively rapidly. This object is achieved because a Hall element of a Hall sensor is placed in the cylinder wall of the master cylinder, and because a magnetic zone is arranged in the piston-and-cylinder assembly so that the Hall element responds to the piston movement within the cylinder.Type: GrantFiled: October 24, 2001Date of Patent: May 3, 2005Assignee: Continental Teves AG & Co. oHGInventors: Hans-Jörg Feigel, Ralf Jakobi, Wilfried Wagner, Dieter Merkel, Ingo Knewitz
