<p><P>PROBLEM TO BE SOLVED: To improve control response by reducing variable control start necessary pressure difference of swash plate angles and improve controllability by enabling to perform minute displacement change easily and accurately in a low displacement range in relation to control of a control valve in a swash plate compressor. <P>SOLUTION: In this swash plate type compressor, a plurality of cylinder bores is arranged in a radial shape, pistons are inserted in every cylinder bores in such a manner that the same can freely reciprocate, and each piston is engaged with a swash plate for converting rotary motion of a compressor drive shaft to reciprocating motion of the piston, a control valve capable of adjusting crank chamber pressure is provided between a delivery chamber and a crank chamber, a passage capable of making communication among the plurality of cylinder bores, and means controlling communication/non-communication of the passage (especially a piston valve 18) is provided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
