Abstract

PURPOSE: To control the capacity of a rotary compressor easily by using a sliding stopper to be fitted to a recess provided on a sliding blade comprising rotary compression elements and stopping the sliding blade properly to give racing to at least one of rotary compression elements.
CONSTITUTION: For the operation of a light load, when a high-pressure solenoid valve 27 is closed and a low-pressure solenoid valve 26 is opened for giving a low- pressure lower than the high-pressure in an airtight vessel 8 to a diaphragm 23, a stopper 25 of a fixing device 20 is inserted into a recess 21 of a sliding blade 14 of a rotary compression element 4, as the total spring constant of the diaphragm 23 and a spring 24 is smaller than the high pressure in the airtight vessel 8. In this construction, the sliding blade 14 is fixed not to be in contact with a roller 12 eccentrically rotating in a cylinder 10 for preventing changes in the capacity of the cylinder 10, and one compression element 4 in rotary compression elements 3 and 4 is controlled for rotating the roller 12 without any load under a constant state of the inner pressure in the cylinder 10.
