ABSTRACT:
A four-way diverter valve has a cylindrical housing wall (10) and two pair of in-line ports (16-19) for connection to a heat exchanger condenser (3). A diverter element (20) is mounted for rotation on a transverse axis (25). The diverter element has a baffle (22) which forms fluid flow passages (23, 24). Radial ribs (35, 36) are disposed on the outer wall of the diverter element. End closure plates (11, 13) for the valve have a first stop device (37, 40) for engagement by the ribs for properly positioning the diverter element in a normal position. A second stop means (43) is provided for rib engagement to position the diverter element in rotated position when the fluid flow downstream of the valve is to be reversed. Diagonally opposed ports (18, 17) are surrounded by concave seats (44, 45) which are inclined at an acute angle to the cylindrical housing wall. The end edges (51) of the diverter element wall and baffle ends (52) are slanted transversely. An axle (26, 27) mounts the tubular diverter element for rotation about its axis. A device (53-59) is provided to shift the axle axially when desired. Resilient seals (39, 42) are provided in association with the longitudinal ribs and stops.
