Claims5
A rotary compressor comprising:
- a compression mechanism including:
- a cylinder;
- an eccentric portion of a shaft that turns inside the cylinder
- a piston rotatably fitted to the eccentric portion and forming a compression chamber between itself and the cylinder and
- a vane including a swing rod and a root portion formed into a cylindrical shape at the end of the swing rod and extending in the axial direction of the shaft,
- wherein the vane extends across the cylinder and the piston and divides the compression chamber into a high pressure space and a low pressure space,
- wherein the cylinder includes a holding portion on its inner surface that rotatably supports the root portion, and the piston is formed with a vane groove into which the swing rod is reciprocally inserted,
- wherein the cylinder includes a clearance portion between a recess portion of the holding portion of the inner surface and the root portion of the vane, and
- wherein the clearance portion is formed so as to extend in the axial direction of the root portion and is formed so as to function as an oil supply passage for guiding lubricating oil between the holding portion and the vane.
