SEALING OF EXPANSION CLEARANCE BETWEEN CYLINDER AND CYLINDER COVER OF INTERNAL COMBUSTION ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed seal has flexible sealing ring adjoining cylinder cover. Sealing ring is rectangle in section with face pointed to cylinder of size chosen so that area of flat section in contact with sealed section of cylinder provides plastic deformation when cylinder cover bolts are tightened up at internal from 20 to 50% of final tightening force, and surface of upper part of ring is made in form of section of torus.

EFFECT: possibility of changing clearance between sealed surfaces in operation without affecting serviceability and possibility of sealing of rough machined surfaces.
