摘要

A valve includes a valve plate (34) coupled to the movable device (24) disposed partially within a housing (26). An electromagnetic actuator (20) includes a first set of permanent magnets (38) provided to the movable device (24). At least one stator core (40) is disposed proximate to the movable device (24) with a gap (42) between the stator core (40) and the movable device (24). At least one stator coil (44) is wound to each stator core (40). A power source (46) is coupled to the at least one stator coil (44) and configured to supply electric current to the at least one stator coil (44). The opening and closing of the valve plate (34) is controlled by changing direction of electric current flow through the at least one stator coil (44).
