Abstract
A pressure reactive piston for an internal combustion engine includes an axially directed central bore formed within a piston ring portion of the piston, which houses a slidably mounted crown which cooperates with the central bore to define a gas chamber which is closed off from the environment by means of a flexible gas seal interposed between the crown and the ring portion of the piston.
