Abstract

The distance between openings of two supply passages that are closest to an accommodating recess is less than the distance between openings of two injection ports that are closest to compression chambers. This configuration minimizes the volume of the space in the accommodating recess between a check valve and the two supply passages, unlike a case in which the distance between the openings of the supply passages that are closest to the accommodating recess is greater than or equal to the distance between the openings of the two injection ports that are closest to the compression chambers. This reduces the flow rate of refrigerant that flows into the accommodating recess from the compression chambers in a compression process through the injection ports and the supply passages.
