<p>A slant plate type compressor is disclosed having a plurality of cylinders (70) formed around the periphery of a cylinder block (21) and a piston (71) slidably fitted within each of the cylinders for reciprocation by a drive mechanism (26). The drive mechanism includes a drive shaft (26) rotatably supported in the compressor housing, a rotor (40) coupled to the drive shaft and rotatable therewith, and a coupling mechanism (50,60) for drivingly coupling the drive to the pistons such that the rotary motion of the rotor is converted into reciprocating motion of the pistons. The coupling mechanism includes a plate (50) having a surface disposed at a slant angle relative to the drive shaft. The slant angle changes in response to a change in pressure in the crank chamber to change the capacity of the compressor. A bias spring (34) is mounted on the drive shaft located between the slant plate and the cylinder block to urge the slant plate toward the maximum slant angle. An inner diameter of the cylinder block end of the bias spring is smaller than a diameter of the drive shaft in order to firmly secure the cylinder block side end portion of the bias spring to the drive shaft.</p> |
