Abstract
659,960. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. June 14, 1949, No. 15778. Convention date, June 19, 1948. [Class 103 (i)] ' In a local-release manually-operated valve for fluid-pressure brake systems of the type described in Specification 591,849, in which, on a certain displacement of the atmospheric valve 27, it is automatically held open by the pressure of air from the auxiliary reservoir, or other chamber, connected at port 3, flowing past, until the pressure has fallen to a certain value, a retaining valve 4, 6 is also provided which is opened after a certain displacement of the valve 27, to allow air from a control or other chamber connected at port 2 to also escape to atmosphere.
