<p>PURPOSE:To enable to supply oil properly without exchanging pipes at discharge and suction ports of oil even in case an engine is reversely rotated by providing two grooves on a shaft. CONSTITUTION:When an output shaft of an engine is reversely rotated, a plunger 24 is moved in the direction of a dotted line. As far as the output shaft of the engine is reversely rotated, the oil supplied from an oil tank and the like is sucked via a suction port 41, a circulation hole 35, a groove 33, and a cam groove 32, and discharged via the cam groove 32, a groove 34, a circulation hole 38, and a discharge hole 44. This construction permits to suck the oil from the side of a Y-joint 49 and discharge to the side of a Y-joint 51 without reference to the rotational direction of the output shaft of the engine.</p> |
