PROBLEM TO BE SOLVED: To provide a compressor having a built-in injection switching valve capable of matching the switching between cooling and heating with the switching of injection.SOLUTION: A compression chamber 30B for injecting an intermediate pressure refrigerant is communicated with an injection passage 52 via a connection pipe 52A and a cylinder chamber 64. A spool valve 66 having a communication hole 66A for connecting the injection passage 52 with the communication pipe 52A is slidable in the cylinder chamber 64. Further, the urging force from a coil spring 69 and the force caused by the outside air pressure from an outside air chamber 68 are applied to one end of the spool valve 66, and the pressure of an intake refrigerant from an intake pressure introducing pipe 62 is applied to the other end. In a cooling and heating circuit, the pressure of the intake refrigerant is changed between a cooling time and a heating time, and the force to be applied to the spool valve 66 is changed. Thus, the spool valve 66 slides in the cylinder chamber 64, enabling connection or disconnection between the injection passage 52 and the compression chamber 30B. |

PROBLEM TO BE SOLVED: To easily avoid supply shortage of lubricating oil to a compression chamber in the case of rotating speed becoming low by providing an oil nozzle for jetting oil, and a valve element for opening/closing an oil passage inlet of the oil nozzle by the elasticity of a spring.
SOLUTION: When differential pressure between pressure in a closed container and pressure near an intake position of refrigerant gas acting upon the outlet side of an oil nozzle 53 is small, the elasticity of a spring 54 is strong, so that a valve element 56 is pushed away toward the fixed plug 57 side to open an oil passage inlet 55. Lubricating oil stored in the closed container flows in the direction of an arrow mark via a lubricating oil return passage 58 and a lubricating oil branch passage 59 and passes the intake position so as to be injected into a scroll compression element. In the case of differential pressure being high, the valve element 56 is moved toward the oil nozzle by this differential pressure, and the inner surface of the valve element 56 comes in contact with the oil passage inlet to close so as to stop injection of lubricating oil.

PURPOSE: To prevent the generation of abnormal noise by providing an opening and closing means which has an injection passage for oil or a liquid refrigerant opened to an intake gas route and closes the injection passage when a detecting value by a pressure detecting means exceeds a set value and opens it when the detecting value is below the set value.
CONSTITUTION: An injection passage 24 for oil and a liquid refrigerant is opened to an intake gas route 25, and a pressure detecting means to detect a high pressure or a low pressure is provided. An opening and closing means to close the injection passage 24 when a detecting value by the pressure detecting means exceeds a set value and open the passage when the detecting value is below the set value is provided. As a result, when operation is executed under a low pressure condition and inclination phenomenon occurs to a moving scroll 4, an oil film or a liquid film is formed between spiral bodies 3b and 4b by means of the oil or the liquid refrigerant injected through the injection passage 24. The oil film relaxes impulsive interference of the spiral bodies 3b and 4b, and reduces the generation of abnormal noise.
