Abstract

Internal combustion four-stroke-cycle engine utilising a rotary sleeve or jacket timing system, which rotates at half speed (or multiples) with respect to the engine axle, comprising a fixed cylinder (1) with head (7), a rotary sleeve (2) top-closed by a ceiling (3) and provided with a window fit for sequentially placing itself in correspondence with a feed duct and an exhaust duct obtained in the head, and at least a rolling and radial centring element (16) so assembled as to originate a small clearance (17), in order to allow the sleeve an axial translation movement such as to push the upper ceiling (3) surface against the lower head (7) surface, until they mate and tight-fit together, ensuring in his way a perfect gas-tightness during compression and combustion.
