Tilting plate type compressor

Abstract

A tilting plate type compressor includes a tilting plate capable of adjusting its tilted angle to a drive shaft, a compression mechanism to be driven by tilting rotation of the tilting plate, a sleeve capable of adjusting the tilted angle of the tilting plate by sliding along the drive shaft and a stopper for fixing the sleeve at a position for setting the tilted angle of the tilting plate to a minimum angle. Flanges are provided on the sleeve to be contacted with the stopper for fixing the sleeve at the position. The tilting plate type compressor can prevent growing large of its size by downsizing its sleeve and can secure a stable discharge amount.

1 . A tilting plate type compressor comprising:
 a tilting plate capable of rotating together with a rotation of a drive shaft and capable of adjusting a tilted angle thereof to the drive shaft;   a compression mechanism including pistons and cylinders for suctioning and compressing refrigerant while the pistons are reciprocated due to tilting rotation of the tilting plate to discharge the refrigerant from the cylinders;   a sleeve capable of adjusting the tilted angle of the tilting plate by sliding along the drive shaft; and   a stopper for fixing the sleeve at a position for setting the tilted angle of the tilting plate to a minimum angle, wherein   flanges are provided on the sleeve to be contacted with the stopper for fixing the sleeve at the position.   
   
   
       2 . The tilting plate type compressor according to  claim 1 , wherein,
 a recess is formed on the stopper for accommodating an end of the sleeve while the flanges are contacting with the stopper.   
   
   
       3 . The tilting plate type compressor according to  claim 1 , wherein
 the flanges are formed only with portions to be contacted with the stopper.   
   
   
       4 . The tilting plate type compressor according to  claim 1 , wherein
 the flanges are provided on the sleeve in a pair with being projected in opposite directions perpendicular to the drive shaft.   
   
   
       5 . The tilting plate type compressor according to  claim 4 , wherein
 each of the flanges has a ring shape,   a pair of pins is inserted within the pair of the flanges, respectively, and   a journal on which the tilting plate is fixed is coupled with the sleeve swingably via the pair of pins.
