EXPANSION COMPRESSOR APPARATUS AND AIR CONDITIONER HAVING SAME

摘要

An expansion compressor apparatus and an air conditioner having same, where the expansion compressor apparatus comprises: an expansion cylinder (10), a compression cylinder (20), and a connecting shaft (30) connecting the expansion cylinder (10) and the compression cylinder (20), an expansion cylinder air suction channel (11) connected to an air suction cavity of the expansion cylinder (10) being provided on the expansion cylinder (10), and the expansion cylinder air suction channel (11) being arranged along a radial direction of the expansion cylinder (10); the expansion compressor apparatus further comprises: a control cylinder (40), the connecting shaft (30) being sleeved inside the control cylinder (40), the control cylinder (40) having a control cylinder air suction channel (41) and a control cylinder exhaust channel (42), the control cylinder air suction channel (41) and the control cylinder exhaust channel (42) both being arranged along a radial direction of the control cylinder (40), and a connecting channel being provided between the control cylinder exhaust channel (42) and the expansion cylinder air suction channel (11). The apparatus effectively solves a problem in the prior art that a high pressure fluid has an impact force in an axial direction on a sector-shaped cam.
