Abstract

1487788 Braking force regulators ALFRED TEVES GmbH 16 Jan 1975 [18 Jan 1974] 1923/75 Heading F2F A brake force regulator comprises a housing 1 with a stepped bore 2 containing a stepped piston 3 of which the smaller surface receives master cylinder pressure and the larger surface transmits pressure to a brake line, first means, in the form of a spring 32, for applying an external control force axially on the stepped piston, a closing member 12 controlling a pressure medium passage 9 in the piston 3 in dependence on the control force, a pressure limiting device 21 in the flow path for a second brake line, means such as a piston 18, 18<SP>1</SP> for transmitting the control force and the pressure prevailing in the chamber in front of the larger piston surface to a closing member 24 of the device 21 to urge it to the opening direction, the second means 18, 18<SP>1</SP> including a locking apparatus which when the pressure in front of the larger piston surface fails will maintain the closing member 24 open during braking. The bore 2 has an annular groove 43 and the piston 18<SP>1</SP> has openings 41 adjacent thereto and containing balls 42, an actuating piston 36 having a ramp 38 causing the balls to retreat from or enter the groove 43.
