    Abstract: The present disclosure relates to a brake cylinder, a brake caliper unit and a rail vehicle. The brake cylinder includes a cylinder block and a cylinder head fixedly sleeved over one end of the cylinder block, the cylinder block being provided therein with a piston, a guide spring, a guide nut, a taper sleeve, an adjusting shaft assembly, a thrust sleeve and a gap adjusting nut assembly; wherein the gap adjusting nut assembly includes a gap adjusting nut, a gap adjusting sleeve and a gap adjusting spring, and a groove extending along an axial direction of the gap adjusting sleeve is formed on an outer circumferential surface of the gap adjusting sleeve, in which groove a release gap adjusting unit is provided. The thrust sleeve spring of the brake cylinder of the present disclosure can recognize excessive elastic deformation of the external lever to prevent the gap adjustment triggered by the excessive elastic deformation of the external lever, ensuring that the release gap of the disc is constant.

    Abstract: A hydraulic brake system includes a hydraulic power booster (11) and a master cylinder (12) connected downstream of the power booster (11). The pressure chamber (21) of the power booster (11) is pressurized by an auxiliary pressure which is dependent on the position of a pedal-actuated brake valve (19). A fast-fill cylinder (40) is can be pressurized by the dynamic pressure and with its aid the working chamber (16) of the master cylinder (12) can be supplied with additional pressure fluid in the initial phase of braking. The chamber (48) between the two piston steps (57, 58) of the fast-fill cylinder connects to the unpressurized supply reservoir (3) by way of a valve assembly (51) for synchronizing the movements of the master cylinder piston (43) and of the stepped piston (45) of the fast-fill cylinder (40). The valve assembly (51) is furnished with the wheel cylinder pressure as a control variable.

    Abstract: A braking system includes a brake actuator which is moveable in a first direction to cause a brake applying member to apply a braking force to a member to be braked. A master valve includes a piston assembly which upon operation of a brake operating member, directs the hydraulic fluid under pressure to the brake actuator to apply the brake. A charging valve is operable in first and second states. The master valve piston assembly includes a pair of coupled pistons separated by a chamber. In a first state, the charging valve connects a source of pressurized hydraulic fluid to the master valve chamber to move the pistons apart, directing a volume of hydraulic fluid to the brake actuator. In a second state, the charging valve connects the chamber to a lower pressure area to allow the pair of pistons to be moved towards one another by a restoring force.
