| 20080289331 | MASTER CYLINDER COMPRISING A HELICAL RESUPPLY GROOVE - Brake master cylinder ( | 11-27-2008 |
| 20100263368 | HYDRAULIC UNIT OF A HYDRAULIC VEHICLE BRAKE SYSTEM - The invention relates to a hydraulic unit of a vehicle hydraulic brake system having a hydraulic block, a storage unit, and a holding unit. The storage unit is inserted into the hydraulic block, and the holding unit is adjusted for holding the hydraulic block locally fixed to an associated vehicle. The storage unit is constructed with a holding surface which forms a section of the outer side of the hydraulic unit, and the holding unit engages with the holding surface of the storage unit in order to hold the hydraulic block locally fixed above the storage unit. Furthermore, the invention also relates to a storage unit where one outer surface of the storage unit which forms an outer side of the hydraulic unit is constructed as a holding surface for attaching the hydraulic block in the vehicle. | 10-21-2010 |
| 20110265469 | RESERVOIR AND MASTER CYLINDER - Provided is a reservoir having first and second partitions. The first partitions partition a brake reservoir chamber and clutch reservoir chambers. The first partitions extend in a length direction of the vehicle and are formed uprightly along the sidewalls. The second partitions connect the first partitions and the sidewalls adjacent to the first partitions. The second partitions are formed uprightly at middle positions of the respective sidewalls in the length direction of the vehicle. The brake reservoir chamber and the clutch reservoir chambers are formed to face the sidewalls. | 11-03-2011 |
| 20130152579 | ASSEMBLY MADE OF A COMPENSATING TANK AND A MASTER CYLINDER FOR A HYDRAULIC MOTOR VEHICLE BRAKE SYSTEM - The invention relates to an assembly made of a compensating tank and a master cylinder for a hydraulic motor vehicle brake system, wherein the compensating tank has two fastening attachments, each with an opening, wherein openings align with an opening in the master cylinder, and the compensating tank is fastened by a detachable connection by a fastening pin that extends through the aligned openings. In order to improve the installation and possible dismantling of the fastening pin, and at the same time to maintain an optimized assembly weight, the invention proposes that the fastening pin be made of plastic and interact in a positive- or force-locking manner with at least one of the openings of the fastening attachments. | 06-20-2013 |
| 20150082787 | MASTER CYLINDER - A master cylinder, for a clutch, actuating or brake system, comprising a cylinder housing with a piston bore, a piston in the piston bore with an end side facing a cylinder chamber and an afterflow opening leading from a piston skirt surface through a piston wall to the cylinder chamber at a distance from the end side, adjoining an afterflow space in a pressure equalization position of the piston where, in the pressure equalization position, hydraulic medium runs into the cylinder chamber to equalize the pressure, and an inner sealing element, arranged between the housing and the piston, limits the cylinder chamber, the afterflow space arranged between the sealing element and the piston skirt surface on a side of a sealing lip of the sealing element facing away from the cylinder chamber, and, in the pressure equalization position, the afterflow opening is located opposite an inner surface of the sealing element. | 03-26-2015 |
| 20150096294 | ROTATING PUMPING APPARATUS WITH SEAL MECHANISM - A rotating pumping apparatus is provided which may be employed in an automotive brake system. The rotating pumping apparatus includes a sealing member and a pressure member. The sealing member is disposed around a pump drive shaft. The pressure member includes a plate spring, a first rotation stopper, and a second rotation stopper. The first rotation stopper serves to stop the pressure member from rotating following rotation of the pump drive shaft. The second rotation stopper engages the seal ring to stop the sealing member from rotating following the rotation of the pump drive shaft. The plate spring works to elastically press the sealing member against a stopper wall of a pump casing to stop the sealing member from moving in an axial direction of the pump drive shaft. | 04-09-2015 |
