Patent JP-H03156187-A (JP)
Title: Rotary compressor
Inventor: WATANABE TAKEJI
IPC: F04C18/356
Filed: 1989-11-14
Abstract: PURPOSE:To reduce friction loss when a rotary compressor is rotated at low and high speed so as to enhance the efficiency of the rotary compressor by causing the centrifugal force of a vane and that of a liner to act in opposite directions, and providing a freely expanding and contracting holder for connecting both of them, and causing a force pressing them in the direction of the center of rotation to work. CONSTITUTION:A vane 5 and a liner 6 are rotated by transmission of electricity. Centrifugal forces thereby act on the vane 5 and the liner 6 in opposite directions and both are connected by a freely expanding and contracting holder 7 and are constantly pressed in the direction of the center of rotation and the vane 5 is rotated while in contact with a piston 2. During rotation at low speed, each of the centrifugal forces of the vane 5 and the liner 6 is small and so the amount of expansion of a holder 7 is small, the force with which the vane 5 make contact with the piston 2 is small, and friction loss is small. During rotation at high speed, each of the centrifugal forces of the vane 5 and the liner 6 is large, but, because the amount of expansion of the holder 7 is also large, the vane is constantly drawn to the center of rotation and the force does not increase. Therefore, the vane 5 will not detach from the piston 2 but keeps in contact with the piston 2 with a proper force and friction loss is small.
