  • the second slide valve 220 moves synchronously to adjust the pressure ratio of the compressor 10, so that the compressor 10 can adjust the pressure ratio of the compressor 10 adaptively when facing different working conditions, and improve the operating efficiency of the compressor 10; when the slide valve assembly In the second working state, the first spool valve 210 and the second spool valve 220 are separated, and a through hole 160 is formed between the first spool valve 210 and the second spool valve 220.
  • the communication of the cavity reduces the compressor flow rate and thus the load of the compressor 10.
  • the size of the through hole 160 becomes larger or smaller, so that the compressor flow and load can be adjusted
  • the compressor 10 of the present application can adjust the pressure ratio of the compressor 10 when the compressor 10 is at full load, and can also adjust the flow rate of the compressor 10, so that the compressor 10 faces different operating conditions , Can maintain high operating efficiency.

Abstract

L'invention concerne un compresseur (10), comprenant : un carter de compresseur (100), lequel est pourvu d'une cavité de distributeur à tiroir ; et un ensemble de distributeurs à tiroir, lequel est disposé à l'intérieur de la cavité de distributeur à tiroir, l'ensemble de distributeurs à tiroir comprenant un premier distributeur à tiroir (210) et un deuxième distributeur à tiroir (220). Le premier distributeur à tiroir (210) est disposé à une extrémité de l'ensemble de distributeurs à tiroir, le deuxième distributeur à tiroir (220) est disposé à l'autre extrémité de l'ensemble de distributeurs à tiroir, et le premier distributeur à tiroir (210) et le deuxième distributeur à tiroir (220) peuvent se déplacer par rapport à la cavité de distributeur à tiroir, de sorte que l'ensemble de distributeurs à tiroir comprend un premier état de fonctionnement et un deuxième état de fonctionnement. Lorsque l'ensemble de distributeurs à tiroir se trouve dans le premier état de fonctionnement, le premier distributeur à tiroir (210) et le deuxième distributeur à tiroir (220) sont attachés et se déplacent de manière synchrone, et lorsque l'ensemble de distributeurs à tiroir se trouve dans le deuxième état de fonctionnement, le premier distributeur à tiroir (210) et le deuxième distributeur à tiroir (220) sont séparés et se déplacent l'un par rapport à l'autre, et le premier distributeur à tiroir (210) et le deuxième distributeur à tiroir (220) forment un trou traversant (160) en communication avec une cavité destinée au montage d'un rotor. L'invention concerne également un climatiseur comprenant le compresseur (10).
