PURPOSE:To feed oil stably by placing a coil spring in an oil tube and carrying oil through utilization of reed of coil spring. CONSTITUTION:Rotation of crank shaft 6 will cause rotation of coil spring 15, auxiliary pump 15a in an oil tube 13b. Consequently, the auxiliary pump 15a will suck oil 14 which is lifted by the reed of coil spring 15 along the coil spring 15 and the inner wall of oil tube 13b and reaches to a hydraulic chamber 16. Then the oil will pass through the oil grooves 6c, 6d, 6e in said chamber 16 to lubricate the bearing 9, rotary piston 8 and main bearing 5a. |
