ABSTRACT:
A diverter valve (1) includes a rotatable axially shiftable element (21) disposed within a housing (10) having a cylindrical wall (11), end walls (12, 14) and four cage bars (42-45). The element has channel plates. One channel plate (29) is disposed adjacent one housing end wall. The other channel plate (30) is disposed intermediate the housing end walls. An end plate (33) is spaced from plate (30) on the side remote from plate (29) and is disposed adjacent the other housing end wall. A tapered plug (27) joins the channel plates and joins plate (30) with end plate (33). Channel walls (34, 35) are spaced outwardly from the plug mounted to the housing wall (11) and extend inwardly between cage bars, with Segmental platforms (50, 51) are their inner edges (52, 53) receiving the edges of channel plate (30) when the diverter assembly (21) is in one position. When the assembly is in normal position, plug (27) is sealed against cage bars (42, 44). Quadrants formed by the cage bars form axial chambers (A-D). Adjacent chambers on each plug side are in communication. Fluid flow is generally straight-through on each plug side. In reverse position, platforms (50, 51) are sealed against plate (30) and walls (34, 35) are sealed against cage bar edges, forming opposed axially extending chambers (E, F). Pairs of transverse axially adjacent chambers are sealed from each other, and are designated as upper (J, L) and lower (K, M) chambers. The lower chambers communicate with axially extending chambers (E, F).
