Abstract
A stroke detection correcting system for variable displacement type compressors comprises a variable displacement type compressor including a plurality of working pistons operatively connected to an internal combustion engine and variable in stroke, a stroke detecting device for detecting the operation stroke of the working pistons, a switching device for changing the switching mode when the stroke of each working piston is in a given range previously set, and a correcting circuit for correcting the detected value from the stroke detecting device on the basis of a predetermined value in accordance with the changing of the switching mode of the switching device. This makes it possible to correct the detected value from the stroke detecting device on the basis of the actual operation stroke of the working piston to provide a substantially correct stroke value, regardless of an error of attachment of and a deterioration with age of the stroke detecting device.
