LASTABHANGIGER BREMSKRAFTREGLER FUR DRUCKLUFTBREMSEN

摘要

A force transmission device for mounting on a vehicle to determine the load has a movable differential piston having a member of smaller diameter including an intermediate deformable medium, connected with a movable member of larger diameter. A valve member connected to a pressure source regulates the pressure in a chamber bearing on the movable member of larger diameter as the position of this member changes thereby causing a greater pressure as the load increases and a lesser pressure as the load decreases. The pressure of this chamber is monitored to operate suitable load responsive devices such as brakes.
