Abstract
463,689. Pressure-regulating valves. SCHMUTZ-BREMSEN AKT.-GES. Sept. 30, 1935, No. 26999. Convention date, Sept. 29, 1934. [Class 135] [Also in Group XXXIV] A control valve for fluid-pressure brakes comprises a pedal-operated piston member S co-operating with a double disc valve member V to control the pressure from a supply line K, R to a brake line Z. The valve member V also controls an exhaust port L<1> which is opened by the pressure of spring F<1> against the piston S when the pressure on pedal P is released. An auxiliary piston G is provided subjected to the controlled brake line pressure, which moves the piston against a spring F<2> and, through a lever connection H, advances the pedal P a distance proportional to the controlled pressure and at the same time moves the piston S back to close the air inlet valve. Reference has been directed by the Comptroller to Specification 424,952.
