20090113891 | MASTER CYLINDER WITH U-SHAPED SEAL - 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 ( | 05-07-2009 |
20090126362 | VEHICLE MASTER CYLINDER CONNECTED TO AN AUXILIARY BRAKING DEVICE - The invention relates to a motor vehicle master cylinder ( | 05-21-2009 |
20090162732 | FUEL CELL EMPLOYING PERIMETER GASKET WITH PERCEIVABLE ORIENTATION INDICATOR - 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. | 06-25-2009 |
20120096848 | CUP OF A MASTER CYLINDER, ADVANTAGEOUSLY A TANDEM MASTER CYLINDER AND TANDEM MASTER CYLINDER PROVIDED WITH SUCH CUPS - “Cup for master cylinder, advantageously a tandem master cylinder, and a tandem master cylinder fitted with such cups” | 04-26-2012 |
20140060037 | BRAKE SYSTEM MASTER-CYLINDER SEAL - 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. | 03-06-2014 |
20140165553 | PRIMARY PISTON FOR A TANDEM MASTER CYLINDER AND TANDEM MASTER CYLINDER EQUIPPED WITH SUCH A PRIMARY PISTON - A primary piston composed of a skirt and an intermediate back wall having a rear face receiving the servobrake thrustrod 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 foam a front face enabling the principal piston to push the secondary piston. The principal piston is made of a single piece of plastic material. | 06-19-2014 |
