摘要:
A valve includes a valve plate coupled to the movable device disposed partially within a housing. An electromagnetic actuator includes a first set of permanent magnets provided to the movable device. At least one stator core is disposed proximate to the movable device with a gap between the stator core and the movable device. At least one stator coil is wound to each stator core. A power source is coupled to the at least one stator coil and configured to supply electric current to the at least one stator coil. The opening and closing of the valve plate is controlled by changing direction of electric current flow through the at least one stator coil.

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.
