ABSTRACT:
A wobble plate compressor including a housing having a cylinder block provided with a plurality of cylinders and a crank chamber is disclosed. A plurality of pistons are coupled to a wobble plate and slidably fitted in the cylinders. A drive shaft is rotatably supported in the housing. An inclined plate connected to the wobble plate is rotated by the drive shaft through a rotor. The rotational motion of the inclined plate is converted into nutational motion of the wobble plate. A rotation preventing mechanism in used to prevent rotational motion of the wobble plate. The rotation preventing mechanism has a guide plate extending within the crank chamber, a cylindrical block including a vertical groove formed therein and retaining system for retaining the cylindrical block on the wobble plate such that the vertical groove is slidably fitted on the guide plate. The retaining system includes a female screw formed on one of the periphery of the wobble plate and the upper surface of the cylindrical block and a male screw provided on the other of the periphery of the wobble plate and the upper surface of the cylindrical block. When the male screw is screwed in the female screw, the cylindrical block is securely connected to the wobble plate by the retaining system. The rotation preventing mechanism can thereby be easily assembled and disassembled.
