Abstract
An improved rotary device (20), such as a fluid pump or motor, includes a housing (24) which encloses a working unit (22). The working unit (22) includes a cam ring (38) which cooperates with a rotor (40) and a plurality of vanes (42) to form a plurality of variable volume working chambers. The housing (24) includes a main section (26) and a cover section (28). The main section (26) of the housing (24) has three separate risers (122, 124 and 126). Any one of the three risers (122, 124 or 126) may be connected with a fluid conduit (116). The main and cover sections (26 and 28) of the housing (24) are movable relative to each other to enable the rotary device (20) to be mounted in a selected one of a plurality of orientations on a support structure.
