Having thus described my invention, what I claim and desire to secure by Letters Patent is: 1. A multiple valve assembly comprising: a ?rst valve body having four equal faces disposed to form a 90° angle with one another about a central axis, a valve re ceiving chamber formed in said body along said axis, a ?rst set of similar ports formed in said body, one each of said ports extending inwardly from one each of said faces between the side edges in line with the central axis thereof to intersect said chamber, each of said ports hav ing its axis in a common plane perpendicular to said cen tral axis, a second set of similar ports formed in said body, one each of said second set of ports extending faces between the edges in line with the central axis thereof, and the axes of each of said second set of ports lying on a common plane parallel to and spaced from the common plane of said ?rst set of ports, whereby each of the faces of said valve body has two ports therein with the axes of said ports intersecting the centerline of the face and being spaced from one another, and valve means in said valve receiving chamber for controlling ?ow from selected ports ofone of said sets of ports to selected ports of the other of said sets of ports.
