Example Embodiment

[0019] The structural principle and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Referring to Figures 1 and 2, a sliding-piston type fluid machine radial flexible compensation mechanism includes a crankshaft 1, a cylinder 2, a sliding sleeve 3, a piston 4 and a butterfly spring plate 5; the crankshaft 1 passes through the cylinder 2. The part of the crankshaft 1 located inside the cylinder 2 is the crankshaft eccentric part 1A. The sliding sleeve 3 is sleeved outside the crankshaft eccentric part 1A. A plane 1a parallel to the crankshaft axis is provided on the outer surface of the crankshaft eccentric part 1A. The plane 1a should be in The front side of the crankshaft rotation direction, the other side is an arc or a plane, the inner surface of the sliding sleeve 3 has a plane 3a that matches the plane 1a, which can slide relatively and transmit pressure; the outer circle 3b of the sliding sle...

Abstract

A slipper-type radial flexible compensation mechanism of a rolling piston-like fluid machine comprises a crankshaft, the crankshaft traverses through a cylinder, the part of the crankshaft positioned in the cylinder is a crankshaft eccentric portion, a sliding shaft sleeve is sleeved to the outside of the crankshaft eccentric portion, the external surface of the crankshaft eccentric is provided with a plane in parallel with the axis of the crankshaft, the plane is arranged in a single-side or double-side manner, and the internal surface of the sliding shaft sleeve has a plane in parallel with the plane; the outer circle of the sliding shaft sleeve is abutted to the inner circle of a piston; and the plane of the sliding shaft sleeve and the plane of the crankshaft eccentric portion cooperate with each other, can slide relative to each other, and can realize the pressure transmission. The outer circle of the sliding shaft sleeve is abutted to the inner circle of the piston, so the outer circle of the piston can be abutted to the inner wall of the cylinder under the common action of inertia force, Belleville spring piece spring force and other outer forces in order to compensate errors generated during making and assembling a pump body, thereby the leakage of a gas from a high pressure chamber to a low pressure chamber is reduced.

Description

Technical field: [0001] The invention relates to a fluid machine, in particular to a slider type radial flexible compensation mechanism of a rolling piston type fluid machine of a rolling piston type compressor, a vacuum pump, a gas-liquid mixed pump and a liquid pump. Background technique [0002] Rolling piston fluid machinery refers to a compressor, vacuum pump, gas-liquid mixed pump or liquid pump used to increase the pressure of gas and liquid, and is widely used in refrigeration and air conditioning systems, vacuum, aviation and military industries. In addition to the commonly known rolling piston type, its structure also includes swing type, swing piston type, hinge slide type and swing slide type. [0003] Rolling piston compressors (also known as rolling rotor compressors or rotary compressors) or pumps are characterized by a circular inner wall of the cylinder that remains in contact with the outer circle of the piston. The piston is sleeved on the eccentric part ...
