Abstract

A compressor includes a compression mechanism, an injection valve disposed in an injection passage, and an injection pipe to supply refrigerant to the injection passage. The injection valve includes a valve body movable along a first direction, a valve presser disposed closer to the injection pipe than the valve body to restrict movement of the valve body toward the injection pipe, and a valve seat disposed closer to a compression chamber than the valve body to restrict movement of the valve body toward the compression chamber. The valve presser has a first hole. The valve body has a second hole. A buffer space communicates with a first space that accommodates the valve body between the valve presser and the valve seat. An opening of the buffer space facing the valve body does not overlap an annular peripheral edge located around the second hole when viewed in the first direction.
