Electromagnetic control valve |
摘要 |
An electromagnetic control valve is provided. The control valve includes a housing defining a bore and a fluid passageway having a seat. A valve element is slidably disposed in the bore and is moveable between a first position where a flow of fluid passes by the seat and a second position where a flow of fluid relative to the seat is blocked. A solenoid having an armature is operatively connected with the valve element. The solenoid is operable to move the valve element from the first position to the second position. A biasing assembly is operatively engaged with the valve element and is adapted to move the valve element from the second position towards the first position. The biasing assembly exerts a first force on the valve element during a first predetermined travel distance from the second position and a second force on the valve element during a second predetermined travel distance. The first force is greater than the second force.
