摘要： A hydraulic brake master cylinder (12) for a vehicle braking system defines a first smaller fluid path (70, 50, 56, 34, 42, 44) and a second larger fluid path (72, 50, 56, 34, 44, 42) for connecting a working chamber (32) with a fluid reservoir at ambient pressure when the cylinder piston (28) is retracted and the brakes are not applied. A pressure relief valve (76) normally closes the second fluid path but is arranged to open when subject to a pressure differential at or above a threshold value. The first fluid path allows a restricted return flow of fluid to the reservoir should a standard knock-back event occur. If a larger knock-back event occurs causing a fluid pressure spike at or above the threshold value, the pressure relief valve (76) opens to allow a higher volume return flow through the second fluid path to dissipate the pressure quickly.

摘要： A hydraulic block of a slip regulation of a hydraulic vehicle power brake system that has a master brake cylinder bore and forms a master brake cylinder. In order to prevent a hard impact of a piston of the master brake cylinder against an end stop when the master brake cylinder is released, in particular when there is an abrupt release, for example when the foot slides off a foot brake pedal, a hydraulic return damper that is integrated in the piston is provided.

摘要： A master cylinder assembly of the type comprises a housing (20) disposed along an axis (A) defining a chamber (22) having a cylindrical shape extending horizontally between an open end and a closed end. A first cylinder (42) and a second cylinder (44) are disposed for sliding movement axially along the axis. Each of the cylinders includes a cylindrical wall (48) defining a cylindrical bore (52). A piston (56) is disposed in each of the cylindrical bores. The cylindrical wall of each cylinder includes a cylinder ramp (70) to define a cylinder ramp shoulder (74). Each piston includes a piston ramp (76) to define a piston ramp shoulder (80). The piston ramp shoulder (80) of each piston and the cylinder ramp shoulder (74) of each cylinder radially engage one another in an assembled position to allow the cylinders (42, 44) and the pistons (56) to abut one another during the sliding movement axially along the axis within the chamber of the housing.

摘要： A master cylinder for a regulated braking system having at least one piston, which is movable in a housing and which is sealed from a pressure chamber by a sealing element arranged in a ring groove of the housing, which can be connected to an unpressurized supply chamber by control passages designed in the pistons. In order to reduce the flow resistance of the control passages at the same dead stroke, the control passages have a control edge designed parallel to a piston end face of at least one of the pistons.

摘要： A brake fluid reservoir is connected to a master cylinder by a neck which is arranged in an upper chamber of the master cylinder. Holes extend through a surface of a piston, opening to a pressure chamber. The piston extends through a bore hole of the master cylinder. A drill hole extends through an interior wall of the master cylinder, opening into the bore hole, thereby providing communication between the fluid reservoir and the pressure chamber. A floating orifice plate is arranged within the upper chamber, between the neck of the brake fluid reservoir chamber and the drill hole, such that the orifice plate forms a baffle that limits a flow rate of liquid from the brake fluid reservoir chamber to the pressure chamber; and includes supports pressing against a surface of the interior wall of the master cylinder and arranged around the first side of the drill hole.
