Abstract

Improvements in control valves for railway vehicle compressed air brake installations, with a control piston loaded by pressure in a main air duct, against the pressure of a control chamber, for actuation of an inlet valve and an outlet valve to put a brake cylinder under pressure, and with an accelerator for the intake of air from the main air duct, which has a control sleeve arranged movable parallel to the direction of the axis of the control piston, which is loaded by a constantly effective force in the direction of movement of the control piston, as its impulsion through the control chamber is predominant, and which is intercepted by a valve seal connected to the control piston, forming the control sleeve together with the valve seal, an acceleration valve arranged between the main air duct and a chamber that can be filled from it by the cap control ring, separated from the atmosphere in the braking state, and featuring a sliding lock for the control sleeve which is actuated by a piston loaded in the blocking direction by pressure in the main air duct and in the direction contrary to the pressure in the chamber, characterized in that the displacement stroke of the control sleeve corresponds at least to the travel of the control piston when closing the outlet valve, because in the pneumatic link from the acceleration valve to the chamber, A nozzle is arranged and because the control sleeve is provided with two piston faces, one of which is under the pressure prevailing in the link between the acceleration valve and the nozzle acting by the valve seal in the direction of lifting of the control sleeve, and the other in the opposite direction under pressure in the chamber.
