ABSTRACT:
A valve assembly for an internal combustion engine includes a stationary permanent magnet assembly having at least one permanent magnet for generating a permanent magnetic field and a movable coil assembly having at least one coil of electrically conductive material for generating a magnetic field when an electrical current is applied to the at least one coil to thereby move the coil assembly with respect to the permanent magnet assembly. A valve is connected to the coil assembly for movement therewith. The valve assembly also includes a housing with an internal cavity and spaced ports extending from the cavity to circulate liquid through the cavity and cool the valve assembly during operation.
