Patent number: 9643579Abstract: A primary piston composed of a skirt and an intermediate back wall having a rear face receiving the servobrake thrust rod and a forward face for the telescoping rod and the spring pushing the secondary piston. The front of the skirt has longitudinal grooves open in front and closed in the rear. The thickness of the skirt beneath the grooves and the part of the skirt between two successive grooves in the peripheral direction form a front face enabling the principal piston to push the secondary piston. The principal piston is made of a single piece of plastic material.Type: GrantFiled: December 1, 2011Date of Patent: May 9, 2017Assignee: ROBERT BOSCH GMBHInventors: Marc Rodriguez, Olivier Bernadat, Laurent Lhuillier, Marc Noblet, Julien Gateau, Daniel Grech, Carole Charpentier

Patent number: 9631724Abstract: A master-cylinder seal housed in a groove around a piston has a core connected to three annular and concentric lips. The core rests against a side of the groove and has: a surface provided with an interior edge followed by a peripheral platter cut by at least one channel, and an exterior crown provided with a connection zone formed by an interruption in the crown and deformable due to pressure within the seal to recreate the crown's continuity and impermeability while facilitating purging the brake system when there is no pressure in the channel and the connection zone.Type: GrantFiled: May 8, 2015Date of Patent: April 25, 2017Assignee: ROBERT BOSCH GMBHInventors: Laurent Lhuillier, Marc Noblet, Olivier Bernadat, Serge Aquino, Julien Gateau, Marc Rodriguez

Patent number: 8991171Abstract: A cup for a master cylinder coming into contact with its primary piston or its secondary piston and subjected to the pressure of the brake fluid of the primary chamber and of the secondary chamber. The cup has two large grooves bordered: by a rib between the heel and the first groove, by a rib between the first groove and the second groove, by a rib between the second groove and the small grooves, these ribs being in protrusion relative to the cylindrical surface of the heel in the mounted position of the cup in order to separate the heel from the surface of the piston and form, between the heel and the surface of the piston, a gap with a film of brake fluid. Master cylinder notably a tandem master cylinder fitted with such cups.Type: GrantFiled: June 11, 2010Date of Patent: March 31, 2015Assignee: Robert Bosch GmbHInventors: Olivier Bernadat, Marc Noblet, Julien Gateau, François Gaget, Marc Rodriguez

Patent number: 8209978Abstract: The invention relates to a motor vehicle master cylinder (1). More specifically, the invention relates to a piston (4, 5) of the master cylinder which has a first indentation (24) and a second indentation (27), which indentations are formed upstream of a port (13, 14) of the piston. The first indentation and the second indentation delimit a space within which hydraulic brake fluid can be stored so that it can be tapped off by an auxiliary braking device of the E.S.P. type.Type: GrantFiled: November 6, 2008Date of Patent: July 3, 2012Assignee: Robert Bosch GmbHInventors: Yannick Nen, Omar Brahml, Marc Noblet, Dominique Rault, Philippe Bourlon, Lionel Bourgols, Jérémy Labarre

Publication number: 20120096848Abstract: “Cup for master cylinder, advantageously a tandem master cylinder, and a tandem master cylinder fitted with such cups” The cup for a master cylinder coming into contact with its primary piston or its secondary piston and subjected to the pressure of the brake fluid of the primary chamber and of the secondary chamber. The cup (60) has two large grooves (622, 624) bordered: by a rib (627) between the heel (621) and the first groove (622), by a rib (623) between the first groove (622) and the second groove (624), by a rib (625) between the second groove (624) and the small grooves (626), these ribs (627, 623, 625) being in protrusion (DS) relative to the cylindrical surface (D) of the heel (621) in the mounted position of the cup (50) in order to separate the heel (620) from the surface of the piston (30) and form, between the heel (620) and the surface of the piston (30), a gap (621) with a film of brake fluid (628). Master cylinder notably a tandem master cylinder fitted with such cups.Type: ApplicationFiled: June 11, 2010Publication date: April 26, 2012Applicant: ROBERT BOSCH GMBHInventors: Olivier Bernadat, Marc Noblet, Julien Gateau, François Gaget, Marc Rodriguez

Patent number: 8109088Abstract: Our problem relates to a master cylinder with a U-shaped seal. Our goal is to avoid defective bleeding of hydraulic braking systems. The defects arise out of the fact that the vacuum causes the lips of the seal (21) to stick together and to stick against the wall (41). To achieve this, reliefs (42) will be created on one wall (44) of one lip (28) facing the other lip (27) and on the edge face (50) of this same lip. These reliefs will prevent the lips from sticking tightly to one another and to the wall facing the edge face of the lips. This lack of sticking will prevent a vacuum from being created between the two lips and between the edge face of the lips and the wall (41). As a result, the seal will be able to return to a position in which bleeding can be performed effectively.Type: GrantFiled: November 6, 2008Date of Patent: February 7, 2012Assignee: Robert Bosch GmbHInventors: Daniel Grech, Antony Auguste, Lionel Bourgois, Nicolas Quiniou, Marc Noblet, Stéphane Lacroix, Omar Brahmi

Publication number: 20090162732Abstract: A fuel cell assembly includes a first flow field plate (FFP), a second FFP, and a membrane electrode assembly (MEA) provided between the first and second FFPs. The MEA includes first and second gas diffusion layers (GDLs) and a membrane provided between an anode catalytic layer and a cathode catalytic layer. A gasket, provided between the first and second flow field plates and relative to a periphery of the MEA, comprises a first surface having a first human perceivable feature associated with the anode catalytic layer and a second surface having a second human perceivable feature associated with the cathode catalytic layer. At least a portion of the gasket comprising the first and second human perceivable features is configured to extend beyond a periphery of the first and second flow field plates.Type: ApplicationFiled: December 21, 2007Publication date: June 25, 2009Inventors: Marc Noblet, Claude D.

Patent number: 7024854Abstract: A master cylinder with increased safety having a piston produced by molding a plastic or aluminum alloy. The piston slides in a bore blocked off by an end wall. A valve for the master cylinder bears at rest against a pin that is fixedly mounted in the body of the master cylinder passes through the piston via a longitudinal slot. The dimensions of the master cylinder are determined such that the piston bears against the pin before coming into contact with the end wall of the master cylinder body.Type: GrantFiled: September 16, 2004Date of Patent: April 11, 2006Assignee: Robert Bosch GmbHInventors: Hervé Pujol, Serge Aquino, Marc Noblet, Chris Anderson, Thierry Fausten
