Zusammenfassung:	PURPOSE:To control volume precisely by providing gas injection circuits to return gas refrigerant into compression chambers of compression elements, and opening injection holes on the respective compression chambers. CONSTITUTION:A compression chamber 15a of an upper cylinder 4 is separated from a compression chamber 15b of a lower cylinder 5 with a separation plate 6, and respective injection holes 26a, 26b and pipes 27a, 27b are provided independently. And independent injection circuits are connected to injection pipes 27a, 27b from a gas-liquid separator respectively. Thereby as injection holes are provided for respective compression elements, the operation of respective elements can be combined to enable precise volume control of medium pressure or the like.
