Kind Code:
A1
Abstract:
Disclosed are a pump body for a piston compressor with a rotary cylinder and a compressor comprising same. The pump body for a piston compressor with a rotary cylinder comprises a cylinder jacket (10) and a cylinder (20) rotatably arranged in the cylinder jacket (10), wherein an outer circumferential surface of the cylinder (20) is in clearance fit with an inner circumferential surface of the cylinder jacket (10). Since a clearance is provided between the outer circumferential surface of the cylinder and the inner circumferential surface of the cylinder jacket, contact between the outer circumferential surface of the cylinder and the inner circumferential surface of the cylinder jacket is prevented, which helps to solve the problem of severe friction between the cylinder and the cylinder jacket existing in the prior art.
