Abstract

A variable capacity compressor including a pumping device, and a control element the position of which can be changed to determine the capacity of the pumping device. The compressor comprises: a detector for detecting change in the position of the control element in a continuous manner; and a capacity-indicating device for visually indicating an output value thereof in a manner continuously variable in response to a continuous change in output from the detector, whereby the output value visually indicated by the capacity-indicating device varies continuously with a continuous change in the capacity of the pumping device.
