Title: Load controlled brake valve - with bypass venting valve in piston surface to release brakes fully
IPC: B60T8/18
Filed: 1975-09-11
Abstract: The load controlled brake pressure valve has a double action valve element which operates the inlet and outlet pressures for the brakes. It operates at a low threshold pressure for the brakes. In order to ensure a complete venting of the brakes, when the inlet valve is closed a small bypass on the piston surface opens to bleed any brake pressure left in the brakes, back to the return line. This prevents the brakes from 'sticking' and improves the brake wear. The valve reduces the normal residual pressure in the system of 0.5 to 0.6 bar to zero.
