Problems solved by technology

[0012] However, the existing hermetic rotary compressor has a problem that since the suction hole 71 and the discharge hole 72 are respectively formed at the positions close to the two sides of the vane receiving groove 73, there is a problem with the suction and discharge action. The suction and discharge forces of the cylinder will eccentric to one side, which will cause the overall imbalance of the compressor, and this imbalance will cause the compressor to vibrate
That is to say, the rotating shaft can only realize one of the above-mentioned strokes per revolution, so the compression efficiency is low, which is also a problem in the prior art

Abstract

The sealed rotary compressor includes the following parts: cylinder assembly; rotating shaft installed to penetrate the cylinder assembly and to form eccentric part; rotating piston moving together with the eccentric part of the rotating shaft and capable of rotating and revolving inside the sealed space; and several vanes with one end contacting with the rotating piston, inserted into the cylinder body to reciprocate linearly in radius direction, and separating the sealed space to compress the refrigerant sucked via the sucking holes and exhaust via the exhaust holes. Each turn of the rotating shaft can realize several strokes and this raises the compression efficiency. The sucking force and the exhaust force produced with the compression of the refrigerant are symmetrical about the cylinder axle, and this can prevent vibration of the compressor caused by unbalance.

Description

technical field [0001] The present invention relates to a hermetic rotary compressor (HERMETIC ROTARY COMPRESSOR), more precisely, the present invention relates to a hermetic rotary compressor with the following functions: it can form several cylinders inside the cylinder for cooling the refrigerant Inhale, compress and then discharge the processed compression space, so that the compression efficiency can be improved, and the vibration can also be reduced by balancing. Background technique [0002] Hereinafter, a conventional hermetic rotary compressor will be described with reference to the drawings. figure 1 It is a longitudinal sectional view of an existing hermetic rotary compressor, figure 2 It is a side view showing the operating state of a conventional hermetic rotary compressor. [0003] As shown in the figure, in the existing hermetic rotary compressor 1, an electric structural component 20 is provided at the upper end of the interior of the airtight container 10...
