Abstract
A leak proof, completely sealed solenoid valve, comprising a housinghaving a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coilcoiled around a bobbinsupported by a magnetic bracketwith terminal pinsconnected to the bobbinfor receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppetshaft that obstructs the flow; wherein, the bobbincomprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbinand the housingto prevent internal leakage; and the completely sealed solenoid valve limits emissions and evaporations of the volatile fuel components into and from the valve, and contribute to reliability and robustness of the product by completely sealing the nozzle and housing using laser welding.
