Abstract

261,968. Ackermann, G. March 13, 1926. Multiple-way valves.-In a combined rotary spherical, lift, and rotary cylindrical multiple-way valve for use in compressed-air couplings, the axes L, S of the tube connecting unions are disposed at an obtuse angle to give a large swing from the closed position, shown in the Figure, to its open position. In the closed position a lateral arm m of the upper hollow pivot is raised upon a cam fillet t formed on a fixed disc g; this holds open the lift closure p and vents the interior of the valve to atmosphere through ports r, l in the rotary cylindrical valve formed by the hollow bottom pivot. On opening the main valve, the initial movement causes the arm m to ride off the fillet t to close the lift valve p, and also closes the cylindrical valve ports at r, l, thereby isolating the interior of the valve from the atmosphere. The open and closed positions of the valve are located automatically by means of a roller o on a key slide n which is pressed against a cam surface v by a spring located inside the upper hollow pivot. From either the open or closed positions the roller o mounts the cam v, and after passing the crown of the cam runs down on the other side and definitely locates the next position of the valve.
