ABSTRACT:
A pair of bearing support members (48, 50) are located within opposite end portions (12, 14) of an elongated housing (10). Piston drive rings (58, 68) are mounted for rotation on oblique inner end portions of the bearing support members (48, 50). A cylinder block (44) is mounted for rotation within the housing (10) between the bearing support members (48, 50). The cylinder block (44) includes a plurality of axial bores (46). A pair of pistons (70, 72) reciprocate within each bore (46). Each piston (70, 72) is connected to the piston drive ring (58, 68) at its end of the housing (10) by means of a connector rod (74, 76). An inlet scroll (206 or 208) and an outlet scroll (206 or 208) communicate with center regions of the cylinder bores (46). A system of drive shafts (230, 238) and gears (232, 234, 236, 240) rotate the bearing support members (58, 68) in opposite directions, to change the relative positioning of the oblique piston drive rings (58, 68) relative to each other, to in this manner, change the stroke length of the mechanism and/or the direction of fluid flow through the mechanism.
