ABSTRACT:
A circular cylinder (12) is formed with a plurality of bores (18), (19), (21), (23) in which double acting pistons (33) are slidably disposed. A diagonally oriented swash plate (24) reciprocates the pistons (33) for compressively displacing fluid through the bores (18), (19), (21), (23). A lower portion of the cylinder (12) defines a lubricant sump or chamber (81) in which a lubricant oil is contained. The swash plate (24) is partially immersed in the oil for spash lubrication.
Cylinder heads (63), (73) are fixed to the opposite ends of the cylinder (12) and are each formed with an inlet chamber (68), (76) and an outlet chamber (71), (77). Partitions (121), (126) formed in the cylinder (12) sealingly define secondary chambers (122), (127) in the lubricant chamber (81) which may communicate with either the inlet chambers (68), (76) or the outlet chambers (71), (77) to constitute extensions thereof.
