Abstract

PURPOSE:To improve the operating efficiency and to reduce the power consumption, by forming the chip of a vane such that the entire width will contact effectively with the cam face thereby reducing the heat production considerably. CONSTITUTION:A parallel line is provided from the side of a vane 3 at the angular point (j) side with the dimension of the length t20 from the long sliding side face of the vane 3 and the center of the curvature of the vane chip 3a obtained from a specific formula thus to obtain the cross point (k) between said parallel line and the circumference 3b of the vane 3 having the center of the housing 1. The radius of curvature (r) of the vane chip 3a is obtained from another specific formula, and the vane chip 3a formed by describing an arch with the radius (r) around the point (k) has such shape as designed by the radius of curvature (r) which may be the maximum in the range smaller than the radius of curvature of the cam face 1a. Consequently the entire width of the chip 3a will be used while contacting effectively with the cam face 1a thereby the generated heat can be reduced considerably resulting in the improvement of the operating efficiency and the reduction of the power consumption.
