Abstract
A compact scroll fluid device includes a pair of wrap support elements with one of the wrap support elements having an inner axial surface formed with an involute spiral recess and the other of the wrap support elements having an involute spiral wrap member projecting from an inner axial surface thereof. The spiral wrap member is received within the spiral recess while being relatively movable about an orbital path therein. A synchronizer assembly is provided axially between the wrap support elements, radially inwardly of both inlet and outlet zones associated with the scroll fluid device and radially outwardly of an orbit center of the device. The entire scroll fluid device is preferably made of plastic. With this arrangement, an extremely compact and inexpensive device is provided.
