Compressor and refrigeration cycle system therewith

Abstract

The invention discloses a compressor and a refrigerating cycle system thereof. The compressor comprises: a cylinder having a first suction port and a first discharge port and defining a connection between the first suction port and the first The cylinder hole of the exhaust port, the cylinder is provided with a chute connecting the cylinder hole, and the cylinder is provided with an air valve groove along the radial extension direction of the chute, and the air valve groove is located on the radial outside of the chute; the piston can be eccentric It is rotatably arranged in the cylinder bore and has a central hole; the crankshaft is provided with an eccentric shaft, and the eccentric shaft is passed through the central hole; the sliding plate is slidably arranged in the slide groove and the end facing the piston stops against the piston On the top, the end of the sliding plate away from the piston is provided with a step; the main bearing and the auxiliary bearing are respectively sleeved on the crankshaft and located on the upper and lower sides of the cylinder; the valve assembly, the valve assembly is arranged in the valve groove, and at least One, together with the valve assembly, the stepped part and the cylinder, defines the second working chamber, which is easy to process, low in cost, tight in fit and low in power consumption.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and a refrigeration cycle system with the same. Background technique [0002] The compression mechanism of the compressor in the related art cooperates the piston and the sliding vane in a hinged manner. In this matching mode, the processing accuracy of the fitting groove on the head of the sliding vane and the piston is very high, and at the same time, due to its large height , but the diameter is very small, the processing is difficult, the time required to process a single workpiece is long, the cost is high, and it cannot meet the needs of large-scale mass production, and there is still a gap between the head of the slide plate and the matching groove on the piston. During the operation of the machine, the sliding plate and the piston will still collide, which will generate a lot of noise. In addition, due to the large contact area between the two, the fricti...

[0002] The compression mechanism of the compressor in the related art cooperates the piston and the sliding vane in a hinged manner. In this matching mode, the processing accuracy of the fitting groove on the head of the sliding vane and the piston is very high, and at the same time, due to its large height , but the diameter is very small, the processing is difficult, the time required to process a single workpiece is long, the cost is high, and it cannot meet the needs of large-scale mass production, and there is still a gap between the head of the slide plate and the matching groove on the piston. During the operation of the machine, the sliding plate and the piston will still collide, resulting in a large noise. In addition, due to the large contact area between the two, the friction power consumption is also large.
