<p><P>PROBLEM TO BE SOLVED: To reduce high slide friction occurring between a swash plate and the shoe of a piston due to suppression of rotation of a swash plate and prevent worsening of vibration, noise and volume controllability occuring therewith, in an oscillating swash plate type pump (containing a compressor). <P>SOLUTION: An oscillating swash plate 6 with which one end of a piston 7 is slid and engaged is supported through bearings 61 and 62 by a drive plate rotating in a state to be inclined and coupled to a shaft 4, and the occurrence of slide friction is reduced by suppressing rotation of the swash plate 6. However, as the usual state of the swash plate pump, an axial force to further increase the inclination angle of the oscillating swash plate by a compression reaction force exerted on the piston is applied on the oscillating swash plate 6, and since, in this case, rotation of the oscillating swash plate 6 is suppressed, a dynamic balance can be kept by its centrifugal balance. Accordingly, a drive plate 5 is provided with a balancer 52 and the restoring force of an inclination angle is generated by a centrifugal force. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
