Abstract
Fluid valves for use in internal combustion engines incorporate both plastic and metal housings which are joined at the inlet end to a metallic adapter by means of staking portions of the adapter over the exterior of the valve inlet housing tube. Valves having this type of connection are prone to failure caused by abuse encountered during valve installation and engine maintenance. In the present invention a fluid valve (10) is provided having superior strength at the junction between a plastic inlet (34) and a threaded metallic engine block adapter (14). A portion of the adapter extends into the inlet end of the housing and has a circumferential rib (48) having an outer knurled surface (50) located intermediate and adjacent to a pair of grooves (52, 54). By heating the knurled rib (48), the plastic material of the hollow inlet portion of the valve housing flows into and conforms with the grooves and the knurled rib thereby providing a rigid connection between the valve housing and the adapter. A seal ring (58) is mounted in a groove formed in the adapter and functions to fluidly seal the adapter to the inlet end of the housing.
