HYDRAULIC VALVE LASH ADJUSTER FOR INTERNAL COMBUSTION ENGINES |
摘要 |
A hydraulic valve-clearance compensating element for internal combustion engines in which an internal valve stem is capable of being axially shifted relative to an external stem such that, together with the latter, it delimits an oil-filled storage chamber. The volume of the storage chamber may be altered and is sealed to the outside by a gasket. At least one compressible displacement member is included in the storage chamber to offset changes in volume. This displacement member is made of a closed-celled soft foam with a non-porous surface layer. |
