摘要： An apparatus and method for controlling fluid flow is disclosed. An electromagnetic actuator may include a stator having an inner pole member and an outer pole member. The outer pole member may have a fluid passageway therein for transmitting fluid through the outer pole member. The actuator may further include a coil disposed around the inner pole member and arranged between the inner pole member and the outer pole member. The actuator may also include an armature moveable under the influence of a magnetic field generated by the stator and coil and operable to affect transmission of the fluid through the fluid passageway.

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.
