Device for sealing engine block provided with cylinder, has compensating element, which is inserted in groove of engine block or recess of cylinder head opposite to cylinder to enclose cylinder or cylinder liner

摘要

#CMT# #/CMT# The device has a compensating element (5), which is inserted in a groove (4) of an engine block (1) or a recess of a cylinder head opposite to a cylinder (2) to enclose the cylinder or a cylinder liner. The compensating element is formed by a base material flowing in an operating condition of an internal combustion engine and a cover element. The base material is formed by a viscous or visco-elastic medium, particularly a polymer or a polytetrafluoroethylene. The base material is formed by a low melting metal or a metallic alloy. #CMT#USE : #/CMT# Device for sealing an engine block provided with a cylinder. #CMT#ADVANTAGE : #/CMT# The device has a compensating element, which is inserted in a groove of an engine block or a recess of a cylinder head opposite to a cylinder to enclose the cylinder or a cylinder liner, and hence ensures optimized compensation of changes of the dynamic sealing gap oscillation by the sealing device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an engine block. 1 : Engine block 2 : Cylinder 3 : Threaded hole 4 : Groove 5 : Compensating element.
