ABSTRACT:
A variable capacity vane compressor uses a linear actuator. The linear actuator is pivotally connected to a valve plate to rotate the valve plate between minimum delivery and maximum delivery positions. The actuator has springs on each end which bias the actuator to an equilibrium position between the full and minimum delivery positions for start up. Control pressure is supplied to one side of the actuator while the other side of the actuator is at intake pressure.
