Abstract
1,246,936. Fluid pressure brakes. WERKZEUGMASCHINENFABKIK OERLIKON BUHRLE A.G. 3 June, 1969 [7 June, 1968], No. 28129/69. Heading F2F. In a direct release diaphragm-controlled dual pressure control valve arrangement for compressed air brakes, e.g. for rail vehicles having an idle movement between the closing of the outlet valve and the opening of the inlet valve for loading the brake cylinders 1 and having an idle movement between the closing of the inlet valve and the opening of the outlet valve for venting the brake cylinder there is provided an additional valve 60, 61 which is operated by a control diaphragm 12 within the idle movements and an additional diaphragm 22 acting on the control diaphragm push rod and arranged to be loaded by an air pressure controlled by the additional valve 60, 61 to produce a force opposing opening of the outlet valve and which force on release of the brakes disappears when a predetermined difference is reached between the pressure in an auxiliary air tank 18 and the pressure in the main pipe 16 before the venting of the brake cylinder 51.
