SOLENOID VALVE HAVING A TWO PIECE MOVING VALVE ELEMENT
摘要:
A system and method for operating a solenoid valve is disclosed. The solenoid valve is operated by moving a first valve element (4) with respect to a second valve element (6, 7) a first distance. And then pulling the second valve element (6, 7) with the first valve element (4) a second distance where the second valve element (6, 7) moves against resistance from a seal (8) and where the movement of the second valve element (6, 7) opens a gap with respect to an orifice (10). The second element (6, 7) then moves a third distance under spring load to open an increased gap with respect to the orifice (10).
