Abstract
A scroll compressor includes an adjustable actuator mount that changes the relative position of a non-orbiting scroll and an orbiting scroll to change the compressor capacity. In one embodiment, the scroll wrap and base of each scroll are manufactured as two separate components with a wrap modulator between the scroll wrap and the base of each scroll. As the mount moves the scrolls apart and together, the wrap modulators extend and retract the scroll wraps relative to their respective bases to maintain fluid-tight compression chambers.
