Abstract
Improvements in control valves for compressed air brakes, especially of railway vehicles, with a three-pressure organ for indirect or direct control of brake cylinder pressure, and a maximum pressure limiter that limits the pressure rise in the brake cylinder at a predetermined maximum value, in a connecting pipe between the reserve tank and the inlet valve of the three-pressure member, the maximum pressure limiter being driven in the closing direction by the pressure in the connecting pipe between the valve of entrance of the organ of three pressures and the seat of the limiter of pressure, maximum and being developed as a valve piston the valve body of the maximum pressure limiter arranged in a pressure chamber that is under the action of the pressure of the tank of reserve, and that is discharged from the pressure of the reserve tank, which reaches its closing position at a certain discharge pressure in the part of the connecting pipe located between the three-pressure member and the maximum pressure limiter, characterized in that the valve piston has, for the reduction of the pressure acting on the valve piston that is in open position, a directing body of current acting in cooperation with the valve seat belonging to the valve and the drill that joins it, with at least one channel that on the one hand opens into the area of lowest pressure in the current around the body, and on the other hand communicates with the side of the piston opposite the valve seat.
