Title:
ROTARY TYPE COMPRESSOR
Document Type and Number:
Japanese Patent JPS6229786
Kind Code:
A
Abstract:

PURPOSE: To prevent the reduction in the rigidity of a cylinder and prevent the occurrence of strain in the cylinder by forming the hole in which a spring energizing a vane being in contact with a rolling piston is housed into a crank shape.

CONSTITUTION: On the back of a vane 7 being in contact with the circumferential surface of a rolling piston 4, a spring 8 which energizes the vane 7 is arranged. To house the spring 8, a hole is formed in a cylinder 3, and the hosing space 9 is formed into a crank shape. Thus, the penetrating of the housing space 9 through the cylinder 3 in a line can be avoided, so that the reduction in the rigidity of the cylinder 3 can be prevented. Consequently, the occurrence of strain in the cylinder 3 is prevented, and the mechanical power loss and noise can be reduced.
