Abstract
PURPOSE: To prevent completely fluid from supercompression which engenders in the space at the bottom of movable vanes in such a way that the total area (a) m2 in the section of a bore for preventing supercompression, and displacement stroke volume of the movable vanes in the grooves of a rotor which is as d in oder to open so as to be a >1/100d.
CONSTITUTION: Opening is made so that the total sectional area (a) of a bore 11 for superheating prevention for connecting to the space 9 at the bottom part of grooves 3 of a rotor 2 can be a >1/100d. In this relation, d is the displacement stroke volume m3/S of movable vanes 4 in the grooves 3. By doing such as this, fluid in the space 9 at the bottom part of the movable vanes 4 thrusted into the grooves 3 by compression strokes absolutely releases supercompression of fluid in the space 9 at the bottom part of movable vanes by moving to the space 9 at the bottom part of the movable vanes 4 which leap by air suction stroke on the opposite side by 180° swiftly with the least resistance, which facilitates to prevent the movable vanes 4 from breakage and to preclude cooling lubricating oil from premature deterioration, at the same time with reducing the sliding pressure between the movable vanes 4 and an air cylinder.
