Abstract

PURPOSE: To uniformly hold a clearance between a vane and both bearings by providing grooves increasing and decreasing in a sectional area from a back surface toward a point end, brought into contact with a roller, in both end surfaces opposed to main and sub bearings of the vane.
CONSTITUTION: Grooves 20a to 20d and 21a to 21d respectively increasing and decreasing in a sectional area from a back surface 19c toward a point end 19d in contact with a roller 5, are provided in both end surfaces 19a, 19b opposed to a main bearing 7 and a subbearing 8 of a vane 19. In this way, when the vane 19 makes a reciprocating motion, lubricating oil is allowed to flow in the grooves 20a to 20d and 21a to 21d to generate a pressure according to decrease of the sectional area. Generation of this pressure occurs simultaneously in both the end surfaces 19a, 19b to hold the vane 19 in a position where the pressure is balanced. Accordingly, clearances δa, δb between the vane 19 and both the bearings 7, 8 can be uniformly held.
