Abstract
Provided is a vortex compressor. In the conventional vortex compressor, the fixed vortex disk top board bears the force generated by the pressure inside an enclosed space (compressing room) formed by two vortex disks at the scroll body side. At the side opposite to the scroll body, the fixed vortex disk top board bears the force generated by the pressure inside an ejecting pressure space. Affected by the combined force, the fixed vortex disk top board is deformed and forms a downward projection shape. On the other hand, the return vortex disk is deformed and forms an upward projection shape affected by the pressure worked on the backside of the return vortex disk. As the deformation may cause the tooth crest and the tooth root at the central section of the scroll body to contact with each other, the conventional vortex compressor increases the sliding loss, leads to the decrease of the performance, and reduces the reliability due to the sintering upon the sliding surface or due to the locking. The utility model aims at providing a vortex compressor featuring high reliability and efficiency. To achieve this objective, the upper portion of the top board of the fixed vortex disk is provided with a top board chamber and a connecting path which communicates the top board chamber with the backpressure chamber.

According to this structure; Through being top board chamber 103 with the entire space between fixed eddy plate top plate portion 5b and the loam cake 8; The pressure of top board chamber 103 acts on the scroll body opposition side integral body of fixed eddy plate 5, thereby same with embodiment 1, can reduce the distortion of fixed eddy plate top plate portion 5b.
As previously discussed; According in the disclosed structure of above-mentioned each embodiment; Intermediate pressure acts on the scroll body opposition side of fixed eddy plate top plate portion, reduces making a concerted effort of power that the fixed eddy plate top plate portion bears from scroll body opposition side and scrollwork side, thereby can reduce the distortion of fixed eddy plate top plate portion.
Through reducing the distortion of fixed eddy plate, can alleviate the contact of the scroll body slide part of two whirlpools dish, low in suction pressure and in the so-called high-pressure ratio operation that ejection pressure is high, can prevent that performance from reducing, and further prevents to produce sintering or block reliably.
In addition because tooth top at two whirlpools dishes scroll body, gap that tooth root is provided with are in advance reduced and or be zero, even when low load, also can reduce the leakage of the gas that in pressing chamber, compresses, thereby can improve performance.Therefore, can be provided on the basis of improving performance in the wide operating range scroll compressor that when high capacity, also has high reliability.
And, pressure also not change in the process of compressed action of the dish chamber, the back side, whirlpool of circling round, it is the pressure of constant.Because the top board chamber is communicated with the whirlpool dish chamber, the back side of circling round, so that the pressure of top board chamber also remains in the process of compressed action is constant, thereby the top board chamber and the whirlpool of circling round are coiled the gas of back pressure chamber and are not returned to pressing chamber.Therefore, do not return, do not produce expansion again, the recompression of pressurized gas to pressing chamber from the gas of pressing chamber to circle round dish chamber, the back side, whirlpool and the guiding of top board chamber, therefore, the worry that does not cause performance to reduce because of present embodiment.
