ABSTRACT:
A rotary machine (10) comprises an inner housing (12) having valving means (14) which includes a shaft (15) for directing working fluid through the machine (10) and, an outer housing (16) within which the inner housing resides. A working chamber (18) is defined between the inner and outer housings (12and16). A plurality of gates (20) are supported by the inner housing and are swingable along their respective longitudinal axis between a sealing position in which the gates form a seal against surface (22) of outer housing (16) and a retracted position in which the gates (20) lie substantially against surface (24) of the housing (12).
