燃機関の圧縮比可変装置。 An inner piston is provided on the piston body so that it can be displaced by a predetermined amount, and this inner piston is connected to the connecting rod via a piston pin to form a hydraulic chamber between the piston body and the inner piston. It is characterized by providing an oil passage for supplying working hydraulic pressure through the pin and the inner piston, and also having a stopper that fixes the piston body and the inner piston and releases the fixation in response to the working hydraulic pressure when the working hydraulic pressure is supplied. Compression ratio variable device for internal combustion engines.
