Abstract

PURPOSE:To reduce the weight of a vane by forming a pressure receiving concave at the rear base of the vane placed in a rotor slit, and to control relatively the centrifugal force of the vane by virtue of the hydraulic pressure to the direction of the vane revolution in the concave. CONSTITUTION:When a rotor 7 is turned, low pressure refrigerant gas is taken in a cylinder chamber 4' from a suction port 11, while high pressure gas in the chamber 4' is discharged from a discharge port 13, and the inside of a casing 2 becomes high in pressure to introduce lubrication oil through an oil hole 17. Part of the lubrication oil goes into a slit 8 of the rotor 7 and presses a vane 9 toward the inner wall of the cylinder chamber 4'. At this moment the hydraulic pressure is applied not only by the height of the vane 9 at a pressure receiving concave 10 made on its lower half, that is, to the radial direction of the rotor 7, but also to every direction evenly, which can control the contact pressure of the rotor 7 on the vane 9.
