The invention designs an automatical compensation mechanism with a novel hinge sealing structure used for a spherical compressor based on the Chinese patent ZL03114505.1, wherein a cylindrical surface hinge is formed among a centrepin, a turntable pin boss and a wrist pin boss of the spherical compressor; an embedded lump is arranged in a groove on the pin boss for forming the cylindrical surface hinge; the embedded lump is in a sector block structure in which the two sides are thick and the middle part is thin; the embedded lump is arranged at the bottom of the groove; the embedded lump has a shape adaptive to that of the groove and that of an external cylindrical surface of a semicylinder lug on the pin boss for forming the cylindrical surface hinge and respectively forms seal movable fit with the groove and the semicylinder lug; and when one of the working chambers which are used for alternative compression and are formed at the two sides of the cylindrical surface hinge is in a high pressure state, the embedded lump is pressed at the side surface of the working chamber so as to enable the embedded lump to have slightly relative movement toward the low pressure side, thus the clearances close to the high pressure side between the embedded lump and the groove bottom surface as well as the cylindrical surface of the semicylinder lug are reduced, and the larger the pressure is, and the smaller the clearances are.
Description
technical field [0001] The invention relates to a hinge sealing structure, in particular to the sealing of the hinge structure used for connecting the piston of a spherical compressor and the rotating disk. Background technique [0002] The Chinese patent with the patent number ZL03114505.1 and the patent title "A Variable-capacity Mechanism for Compressors" discloses a new type of volumetric compressor, which has no intake and exhaust valves, fewer moving parts, Small vibration, high mechanical efficiency, reliable sealing and so on. [0003] But in this patent, there is implementation defect in the design of piston and rotating disk connecting hinge structure. In Chinese patent ZL03114505.1, there is a structure in which the piston pin seat matches the turntable pin seat, and is connected together by a center pin to form a cylindrical hinge connection. In this structure, a half-cylindrical groove is formed in the middle of the two pin seats. This structure is not suitabl...
