Abstract

PURPOSE:To eliminate the oil groove on a movable vane so as to enable the cost to be cut down by lubricating an oldham ring part by allowing lubricating oil to be sprayed out by means of a centrifugal force, from the slit between a crank and the movable vane. CONSTITUTION:An oil sump 11 is formed in the lower part of a case, and a crankshaft 13 is arranged in the oil sump. Said crankshaft 13 is equipped with an oil pump 15 on its top edge, and oil is pumped-up to a crank part 17. The oil which reaches the crank part lubricates the crank part, passing through the oil groove 19 on the crank, then is gushed outside by a centrifugal force, from the slit 13 between the crank and a movable vane 21, and lubricates an oldham ring part 25. Then, the oil returns to the oil sump 11, passing through an oil pit 27.

It measures down.

［発明の実施例］ 以下第２図を用いて本発明の実施例について説明スる。[Embodiments of the invention] Embodiments of the present invention will be described below with reference to FIG.
