Title:
FLUID MACHINERY AND HEAT-EXCHANGE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/140208
Kind Code:
A1
Abstract:
Disclosed is fluid machinery, comprising an upper flange (50), a lower flange (60), a cylinder (20), a rotary shaft (10), a limiting plate (26), a piston bush (33) and a piston (32). The cylinder (20) is interposed between the upper flange (50) and the lower flange (60). The limiting plate (26) has an accommodating hole which is used for accommodating the rotary shaft (10) and is arranged coaxially with the cylinder (20). The limiting plate (26) is interposed between the lower flange (60) and the cylinder (20). The piston bush (33) is pivotally arranged within the cylinder (20). The piston bush (33) has a connecting convex ring (331) extending toward a side of the lower flange (60). The connecting convex ring (331) is embedded in the accommodating hole. The piston bush (33) is in contact with one of the limiting plate (26) and the lower flange (60) in an anti-pushing manner in the axial direction of the rotary shaft (10) and is in clearance fit with the other. The piston (32) is slidably arranged in the piston bush (33) to form a volume-variable cavity. The rotary shaft (10) passes through the upper flange (50), the cylinder (20), the piston bush (33), the piston (32), the limiting plate (26) and the lower flange (60) so as to drive the piston (32) to slide in the piston bush (33). Further disclosed is a heat-exchange apparatus having the fluid machinery. The fluid machinery solves the problems of low operational stability of fluid machinery and low operating efficiency of compressors in the prior art.
