ABSTRACT:
The improved fuel injection valve assembly includes a valve body adapted for mounting in a cylinder head of a reciprocating gas engine including a valve seat sealing between the cylinder head and the valve body; a valve stem with a frustoconical end portion sealingly engaging the valve seat with stem threads at the opposite end for a tappet nut; a spring biasing the frustoconical end portion into sealing engagement with the valve seat; a stem piston guiding the valve stem within the valve body; an annular seal sealing the annulus between the valve body and the stem piston; an oil permeable bushing with a lubricating fluid reservoir positioned between the stem piston and the valve body; a rocker arm pivotally mounted on a rocker arm support mounted on the cylinder head; a push rod engaging one end of the rocker arm; and a tappet button positioned on the opposite end of the rocker arm. This improved fuel injection valve assembly allows lateral removal of the tappet button from the rocker arm to allow the rocker arm to pivot to a first position allowing disconnection of the push rod from the rocker arm which allows the rocker arm to pivot to a second position allowing the fuel injection valve to be serviced in place or removed from the cylinder head for replacement without removing the rocker arm or rocker arm support.
