Abstract

PURPOSE: To securely regulate capacity of a centrifugal compressor by providing with one valve on the suction side which is combined with an eccentric cam, and driving shafts which are respectively connected with a cam guide at one end and a diffuser at the other, thereby simplifying construction.
CONSTITUTION: When a valve 1 is opened, a movable diffuser 5 is shifted on account of pressure difference between both ends of each driving shaft 4a, 4b. In principle, right and left ends of each driving shaft 4a, 4b are respectively subjected to a discharge pressure from a compressor and a suction pressure, so that driving shafts 4a, 4b are constantly forced to the left side during operation of the compressor. When the valve 1 is opened, the movable diffuser 5 is opened to an extent according to the opening of the valve. Eccentric cam 2a, 2b transmit force in the direction of closing the movable diffuser 5. Said constitution may reduce the number of parts into simple construction and provide exact regulation of capacity.
