  • Variable displacement compressor with stepped shaft
    Patent number: 6705841
    Abstract: A variable displacement piston compressor comprising a housing and a shaft supported within the housing for rotational movement about an axis. The shaft includes a stepped down portion defining a reduced diameter within the shaft. A pin extends generally outward from the shaft and includes a distal end. A sleeve is mounted about the shaft, is slidable along the shaft, and is rotatable with the shaft. The sleeve extends over a portion of the stepped down portion of the shaft and defines a radial gap between the sleeve and the stepped down portion. A swash-ring is supported on the sleeve and is rotatable with the shaft. The swash-ring is pivotably coupled to the distal end of the pin. The swash-ring defines an angle with the axis that is adjustable with respect to the axis. A biasing member engages the sleeve and biases the sleeve along the shaft.
