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.

Master cylinder for a regulated braking system

A motor vehicle hydraulic brake system master cylinder, having at least one piston which is arranged in a housing and displaceable along an axis as a result of brake actuation and to which a pressure chamber which can be connected to wheel brakes, and a refill chamber is assigned, wherein the pressure chamber in the non-actuated state can be connected to a fluid reservoir via a compensating bore and on actuation of the brake can be isolated therefrom by means of a cup seal arranged on the piston in order to build up pressure. The master cylinder having a cup seal arranged in a radially open, encircling groove of the piston which groove is formed by a first and a second radially encircling projection, wherein when the brake actuation is released additional fluid is drawn from the refill chamber in the direction of the pressure chamber via the second projection.

Master cylinder for a motor vehicle hydraulic brake system

A master cylinder for a controlled brake system, including at least one piston which is displaceable in a housing and is sealed with respect to a pressure chamber by a sealing element arranged in an annular groove of the housing, which pressure chamber is connectable to an unpressurized supply chamber by control passages formed in the piston. The pistonis formed in at least two parts, including a main body and an annular control element, the control passages being provided in the control element.

Master cylinder, in particular for a controlled brake system

A master cylinder, especially for a controlled brake system, includes at least one pistondisplaceable in a housing, which is sealed in relation to a pressure chamberby means of a sealing elementarranged in an annular grooveof the housing, said pressure chamber being connectable to an unpressurized supply chamberby means of transverse boresprovided in the piston Several recessesare arranged on an inside surfaceof the pistoninto which the transverse boresopen.

Master cylinder, especially for a controlled brake system

The invention relates to a sealing collar for a cylinder-and-piston unit, wherein the sealing collar is essentially received in a groove that is inserted into the cylinder or the piston, respectively, and the sealing collar comprises two sealing lips, the first sealing lip thereof being acted upon dynamically and making catch at the piston or the cylinder, respectively, while the second sealing lip thereof is acted upon statically and rests on a bottom of the groove. It is the core of the invention that the sealing collar includes a circumferential extension that extends in parallel to the sealing lips, is arranged radially between the first sealing lip and the second sealing lip and projects from the sealing lips in an axial direction.
