Abstract
This invention relates to a vented ball-type angle cock for use at each end of the brake pipe on a railway vehicle in which the brake pipe hose connected to the angle cock outlet is vented to atmosphere in the cock closed position via a drilled passageway extending through the ball valve, a guide bushing carried by the ball valve, and a trunnion on one end of which is rotatably supported the bushing, the opposite end of this trunnion being supported on the bottom of the cavity in the angle cock body in which the ball valve is so disposed that in its open position a communication is established between the brake pipe and the hose that is connected to the hose at the adjacent end of the brake pipe on the next car in a train.
