ABSTRACT:
A swash plate radial piston compressor having a toggle action connection means between the swash plate and pistons wherein each piston makes two reciprocations in its cylinder for each 360.degree. of rotation of the compressor input shaft. Means are provided for varying the angle of the swash plate such that a nutating ring, which encircles the swash plate in journaled fashion around the periphery of the swash plate will vary the length of the stroke of the pistons upon a change in the angular position of the swash plate causing a change of volume displacement of the compressor without changing the head clearance of the radial pistons, thus allowing the compressor to go to zero displacement while the input shaft continues to rotate.
