Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as figure 1 , figure 2 Shown: the existing a kind of rolling piston type compressor, the eccentric part (18) outer peripheral surface of rotating crankshaft (17) driven by motor (16) is equipped with freely rotating rolling piston (13) in cylinder hole (14-2 ) rotates eccentrically, relying on the spring (19) and the back pressure of the gas to make the arc surface (2-3) of the sliding vane (2-3) tightly pressed on the outer cylindrical surface (13-1) of the rolling piston (13), and the cylinder hole (14 -2) Divided into a suction chamber (9) and a compression chamber (10). The rotation of the crankshaft 17 drives the rolling piston 13 to rotate, and at the same time pushes the slide (2) to reciprocate in the slide groove (1) of the cylinder, and repeatedly inhales, compresses, and exhausts in the cylinder bore (14-2). ...

Abstract
The invention relates to a rolling piston compressor for improving the lubricating performance of a slip sheet. A cylinder slip sheet groove is matched with a slip sheet clearance and arranged on a slip surface at an adsorbing cavity side; the position approaching a cylinder hole wall is provided with an axial half-moon-shaped guide rail groove along a cylinder hole; a guide rail block which is matched with a guide rail groove clearance and provided with a half-moon-shaped cross section is configured in the guide rail groove; the axial length of the guide rail block is slightly smaller than the height of a cylinder; when the guide rail block along the axial plane and the slip surface of the slip sheet groove approaching the adsorbing cavity side is in a parallel position, the axial plane of the guide rail block is slightly higher or lower than the slip surface of the slip sheet groove on the cylinder; and the slip sheet groove approaching the juncture position of the slip surface of the slip sheet groove at the adsorbing cavity side and the cylinder hole wall is provided with a chamfer angle or an arc. The rolling piston compressor is always in contact with the guide rail block along the axial plane at the side surface of an adsorbing cavity of the cylinder slip sheet groove, reduces the pressure of the contact surface of the slip sheet and effectively solves the problem of lubrication between the stressed slip sheet and the slip surface of the cylinder slip sheet groove in the prior art.
Description
technical field [0001] The invention relates to a rolling piston compressor, in particular to a rolling piston compressor capable of preventing the side surface of a sliding vane from sticking to the sliding surface of a sliding vane groove. Background technique [0002] An existing rolling piston compressor, such as figure 1 , figure 2 shown. In the structure of the rolling piston compressor, due to the load P generated by the pressure difference between the right side of the suction chamber and the left side of the discharge chamber, the sliding vane is slightly inclined in the sliding vane groove. The right side of the slide on the side of the suction chamber is in line contact with the junction of the right sliding surface of the slide groove of the cylinder and the cylinder bore wall or the junction of the chamfer. In the rolling piston compressors using R22, R410A and other working fluids in the past, although there is a pressure difference to generate a load P tha...
