Document Type and Number:
WIPO Patent Application WO/2022/142338
Kind Code:
A1
Abstract:
A pump body assembly and a fluid machine. The pump body assembly comprises a rotating shaft (30); and a piston (20). The piston (20) is provided with a sliding hole (2011); at least a part of the rotating shaft (30) penetrates through the sliding hole (2011); in a process that the piston (20) rotates along with the rotating shaft (30), the sliding hole (2011) slidably works in conjunction with the rotating shaft (30); and the piston (20) is provided with a piston connection channel communicated with the sliding hole (2011). The pump body assembly can mitigate the problem that the piston hinders circulation of oil in the process of usage of a rotary cylinder compressor.
