Title:
圧縮機および空気調和装置
Document Type and Number:
Japanese Patent JP7401804
Kind Code:
B2
Abstract:
Proposed are a compressor with which high compression efficiency can be obtained with a simple structure, and an air conditioning device provided with said compressor. A compressor (21) has an injection valve (93) disposed in an injection passage (84g) that communicates with a compression chamber (40). The injection valve (93) includes a valve main body (94), a valve guard (95), and a valve seat (96). The valve main body (94) is disposed so as to be movable in a first direction (D1). The valve guard (95) restricts movement of the valve main body (94) toward the injection pipe (92). The valve seat (96) restricts movement of the valve main body (94) toward the compression chamber (40). In the valve guard (95) is formed a first hole (95a) that is closed by the valve main body (94) when a refrigerant flows out from a compression chamber (40). A second hole (94a) is formed in the valve main body (94). In the compressor (21) is formed a buffer space (95c) into which the refrigerant flows after having flowed from the compression chamber (40) into a first space (94) accommodating the valve main body (94) and before reaching the first hole (95a).
