ABSTRACT:
A pressure reducer for hydraulic brake systems comprising a valve formed by the head of a spring-loaded piston and by a sealing ring which is urged by a spring against a step of the housing. Arranged between the spring and the sealing ring is an engaging plate which is carried along by the piston after the piston has travelled an amount smaller than the valve stroke. This results in an exactly defined valve stroke and at the same time results in a quick opening of the valve upon decrease of the inlet pressure.
