Abstract: A leak proof, completely sealed solenoid valve, comprising a housing 14 having a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coil 20 coiled around a bobbin 16 supported by a magnetic bracket 24 with terminal pins 18 connected to the bobbin 16 for receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppet 34 shaft that obstructs the flow; wherein, the bobbin 16 comprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbin 16 and the housing 14 to 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.

Abstract: The present invention provides a system for determining plunger position in a solenoid valve and method therefore. More specifically, the invention provides a solenoid valve having hall sensor for detection of plunger position, which provides feedback including output voltage (digital or analog) respective to its position. The solenoid valve includes a nozzle, a spring, a sealing rubber, a poppet, a magnetic bracket, a rubber grommet, a housing sub-assembly, a soft seal, a sensor assembly, a fix core, a moving core and/or plunger, coil, a bobbin sub-assembly, a fix core plate, magnet holder, a permanent magnet and plurality of terminals.
