And a crankshaft pin portion 8 formed on the crankshaft balancer 7 of the crankshaft 3 so as to be eccentric with the crankshaft, and a slider 9 for converting the rotational movement of the crankshaft 3 into a reciprocating motion. And a shell (10) for guiding the slider (9) so that the slider (9) can move smoothly, a piston (11) formed integrally with the shell (10) and reciprocating therein; A cylinder 12 in which the piston reciprocates, and a head provided on an upper portion of the cylinder It is composed of an assembly (13).

상기 크랭크축(2)의 회전원심력에 의해 밀폐용기내의 하부에 있는 오일(a)이 크랭크축(2)내로 흡상된 후, 흡상된 오일(a)이 크랭크축(2)의 외부로 토출되게 크랭크축(2)의 외주연주에 형성된 오일홀(10)으로 구성하였다.After the oil (a) in the lower part of the sealed container is sucked up into the crankshaft (2) by the rotational centrifugal force of the crankshaft (2), the crank so that the sucked oil (a) is discharged out of the crankshaft (2) It consisted of the oil hole 10 formed in the outer periphery of the shaft 2.
