Abstract
A duty-cycle type electromagnetic injector assembly has a valve and cooperating valve seat with the valve being positioned away from or against the valve seat depending upon whether an associated electrical coil is energized; a housing generally contains the valve and valve seat; a guide closely confines the valve permitting the valve to be freely moved toward and away from the valve seat while constraining movement of the valve in other directions; and a fluid pressure regulator forming a portion of the injector assembly establishes both the static rate and dynamic rate of liquid flow metered by the injector assembly.
