VALVE ASSEMBLY FOR AN INTERNAL COMBUSTION ENGINE AND METHOD OF MANUFACTURING

摘要

The present invention is related to a valve assembly and a method of manufacturing same. An extruded profile (1) is used as a housing (26) of the valve assembly, within said housing (26) a single-component valve-element (14) is injection-moulded, having a shaft-part and a plate-part, by moulding said single-component valve-element (14) within a central bore (2) against said housing (26) during injection moulding. Curing of the single-component valve-element (14) and contracting thereof is allowed, providing for a clearance between the single-component valve-element (14) and components (23, 13, 9) of said housing (26) for relative movement therebetween.
