Claims (3)

旋回スクロール部材と、A orbiting scroll member;
固定スクロール部材と、A fixed scroll member;
前記旋回スクロール部材及び前記固定スクロール部材により形成された圧縮室と、A compression chamber formed by the orbiting scroll member and the fixed scroll member;
前記旋回スクロール部材の背面に位置し、前記旋回スクロール部材を前記固定スクロール部材へ押し付ける付勢力を付与する背面過吸込圧領域と、A rear oversucking pressure region that is located on the back surface of the orbiting scroll member and that imparts a biasing force that presses the orbiting scroll member against the fixed scroll member;
前記圧縮室と前記背面過吸込圧領域とを導通する複数の導通路と、A plurality of conductive paths that connect the compression chamber and the back surface oversuction pressure region;
前記複数の導通路にそれぞれ配置され、前記背面過吸込圧領域の圧力が前記圧縮室の吸込圧よりも所定値以上大きくなると開口する複数の差圧制御弁と、を備えるスクロール圧縮機。A scroll compressor comprising a plurality of differential pressure control valves that are respectively disposed in the plurality of conduction paths and that open when a pressure in the back surface oversuction pressure region becomes greater than a suction value of the compression chamber by a predetermined value or more. 請求項１において、前記複数の差圧制御弁は第１差圧制御弁と第２差圧制御弁とを有し、前記第２差圧制御弁の差圧設定値より前記第１差圧制御弁の差圧設定値の方が大きいスクロール圧縮機。2. The first differential pressure control valve according to claim 1, wherein the plurality of differential pressure control valves include a first differential pressure control valve and a second differential pressure control valve, and the first differential pressure control is performed based on a differential pressure setting value of the second differential pressure control valve. A scroll compressor with a larger valve differential pressure setting. 請求項１又は２において、前記圧縮室の圧力が前記圧縮室で圧縮された流体を吐出する吐出系の圧力である吐出圧よりも所定値以上大きくなると開口するバイパス弁を、前記圧縮室と前記吐出系との間に備えるスクロール圧縮機。3. The bypass valve that opens when the pressure in the compression chamber is larger than a discharge pressure that is a pressure of a discharge system that discharges fluid compressed in the compression chamber by a predetermined value or more, according to claim 1 or 2. A scroll compressor provided between the discharge system.
