Abstract
A valve comprises an electromagnetic actuator including a solenoid. The solenoid includes at least one core, wherein the core is an “E” shaped core or a “U” shaped core and an anchor plate. The solenoid further comprises at least one coil disposed within the core and connected to a set of power electronics to supply current to the coils. The actuator further comprises a plunger connected to the anchor plate and at least one spring configured to guide the plunger. The opening and closing of the valve is controlled by passing current through the coil and the valve is used in acompressor.
