Abstract

A space (19) surrounded by a vertical wall (4) and motor shaft bearing (3b), is formed between oil return path (17) and oil bath. The front peripheral groove (26) performs connection interruption switching of oil supply paths (15,16) and oil return path, when an end of oil return path is connected to cylinder chamber (12) of piston flange front side and other end connected to through-hole for valve guides (21).
