Multi-follower rotary compressor and sectional-compressing method for the same

Abstract

A multi-follower compressor includes a cylinder block, a cam, plural followers, and at least one connecting rod. The cylinder block has a compression room, plural intake channels, plural exhaust channels and plural accommodation rooms, each of which is communicative in space with the compression room and outsides of the cylinder block, and among which a clockwise pattern for arranging one intake channel, one accommodation room and one exhaust channel is applied. The cam inside the compression room sleeves a driving shaft. Each of the followers, nested in an accommodation room, has one end contacting the cam and another end performing an axial movement along the accommodation room. The connecting rod having two ends to couple different followers is displaced with the coupled followers. The followers connected with the connecting rod are located along the same axis in a parallel manner.

         6 . A multi-follower compressor, comprising:
 a hollow cylinder block, further having a compression room, a plurality of intake channels, a plurality of exhaust channels and a plurality of accommodation rooms, in which a clockwise arrangement pattern around the cylinder block including in order one of the intake channels, one of the accommodation rooms and one of the exhaust channels is assigned to arrange the plurality of the intake channels, the plurality of the accommodation rooms and the plurality of the exhaust channels; each of the plurality of the intake channels, the plurality of the accommodation rooms and the plurality of the exhaust channels being communicative in space with both the compression room and outsides of the cylinder block; each of the plurality of the exhaust channels further having a valve to seal the corresponding exhaust channel;   a sleeve cam, located inside the compression room, a portion of a circumferential wall of the sleeve cam being contacted with an inner wall of the cylinder block, sleeving thereinside a driving shaft having one end coupled with a foreign motor;   a plurality of followers, each of the followers being nested in a corresponding one of the plurality of the accommodation rooms, one end of the follower being contacted with another portion of the circumferential wall of the sleeve cam, each of the followers being able to perform an axial movement inside and along the corresponding accommodation room; and   at least one connecting rod, located outside the cylinder block without contacting the cylinder block, one end of the connecting rod being elastically coupled with another end of corresponding one of the followers via a spring member while another end of the connecting rod being elastically coupled with another end of another corresponding one of the followers via another spring member.   
     
     
         7 . The multi-follower compressor of  claim 6 , wherein the end of the connecting rod being coupled with the end of the corresponding one of the followers is moved with the axial movement of the corresponding follower, and the followers coupled with the connecting rod are located either along the same axis or along distinct axes, and in either a parallel manner or a non-parallel manner. 
     
     
         8 . The multi-follower compressor of  claim 6 , wherein the spring member is a compression spring. 
     
     
         9 . The multi-follower compressor of  claim 6 , wherein the plurality of the intake channels, the plurality of the exhaust channels, the plurality of the accommodation rooms and the plurality of the followers are all have the same number. 
     
     
         10 . The multi-follower compressor of  claim 6 , wherein the follower is fixed to the connecting rod by one of screwing and pin-engaging.
