ACCOPPIAMENTO A TENUTA DI GAS E DI LIQUIDO TRA UN CORPO IN MATERIALE PLASTICO ED UN CORPO METALLICO IN ESSO INCORPORATO E PROCEDIMENTO DI ESECUZIONE

摘要

A gas and fluid sealing connection and process for making same are disclosed for connecting between a synthetic resinous material/plastic material body and a metallic body which is embedded therein by flowing the synthetic material in a form under pressure. The metallic body has at least one circumferential groove at its outer side. At least one of the grooves disposed in the region of the plastic to be embedded there is disposed and carried an elastomeric ring which fills the groove in the axial direction and the groove is so shaped that the ring is left with an expansion gap space in the region of the groove bottom. Alternative embodiments dispense with the expansion gap space and utilize a ring which is formed out of closed pore elastomeric foam.
