  • Patent number: 7153105
    Abstract: A compressor is disclosed generally comprising a cylinder block at least partially enclosing a compression chamber, a swash plate housing mounted adjacent the cylinder block, the swash plate housing at least partially enclosing a swash plate chamber, an inlet port in the swash plate housing, and a passageway connecting the swash plate chamber and compression chamber. In certain embodiments, the passageway comprises a fluid channel in the cylinder block. In some embodiments, at least one bearing is disposed in the swash plate chamber such that air entering through the inlet port flows over the bearing before flowing to the compression chamber.
    Type: Grant
    Filed: April 24, 2003
    Date of Patent: December 26, 2006
    Assignee: Haldex Brake Corporation
    Inventors: Robert L. Koelzer, Michael R. Jenkins
  • Patent number: 6883416
    Abstract: A swash plate containment assembly for a compressor is disclosed generally comprising a housing, a drive shaft, a swash plate mounted on the drive shaft, and a gimbal arm connected to the housing and swash plate via rotatable joints. In certain embodiments, the joints are located approximately ninety degrees from each other. In some embodiments, the joints comprise a roller bearing and journal coupled thereto.

  • Publication number: 20020127116
    Abstract: An axial piston compressor produces air supplied to an air system of a vehicle, typically a heavy duty truck through a plurality of pistons held within a stationary block, and the movement of the pistons is predicated through the control of a pivotal swash plate. The pistons are idle in a neutral position of the swash plate, wherein a pressure above the pistons in the cylinder block counterbalances a thrust generated by an actuator upon the plate positioned in a plane extending perpendicular to a drive shaft. The plate oscillates in response to a pressure drop above the pistons causing the actuator to expand toward the plate and exert a thrust exceeding the lowered pressure above the pistons and enabling the swash plate to provide the pistons with reciprocal motion.
