ABSTRACT:
In a load-sensing proportion valve including a control valve disposed in a hydraulic fluid passage extending from a master brake cylinder to rear-wheel brake cylinders, a plunger adapted to operate the conbtrol valve in response to the output fluid pressure from the master brake cylinder, and a stem formed integrally with a load-sensing lever and adapted to urge the plunger to open the control valve in accordance with a current load of a vehicle, a resilient member is interposed in a working position between the plunger and the stem so as to prevent the occurrence of noises from possible contacts between these plunger and stem, when set together.
