An electromagnetically operable fuel injection valve for use with an internal combustion engine. The injection valve includes a non-magnetic housing having a fuel passage therethrough and a fixed magnetic core therein. A magnetic movable armature is floatably movable within a sleeve member within the housing. The movable armature has a nozzle portion of reduced diameter which carries at the exit end thereof a ball valve. A nozzle seat having a fuel discharge orifice is adapted for reception of the ball valve and means are provided for guiding said ball valve into sealing engagement with the discharge orifice.

Electromagnetic fuel injection valve

A serviceable valve is provided for controlling the recirculation of exhaust gases within an internal combustion engine. The valve includes a housing having a first section provided with an interior chamber and a second section secured to and subtending said first section. A diaphragm is affixed to and interposed the housing sections and is in communication with the chamber. In response to a predetermined chamber pressure, the diaphragm is distorted in one direction from a predetermined rest position. The housing is mounted on a fitting, which subtend the housing second section, whereby said housing and the diaphragm are rotatable as a unit about an axis of the fitting to selected positions of adjustment. The fitting is removably mounted on the engine. Carried on the diaphragm is a stem assembly which is movable longitudinally in response to the distortion of the diaphragm. A portion of the stem assembly extends through and protrudes from the fitting and has a valve piece mounted thereon. The valve piece is adapted to coact with a valve seat disposed within a recirculation flow path of the engine exhaust gases and, when seated thereon, blocks recirculation of the exhaust gases through the engine. The housing first section is provided with a port offset from the fitting axis and adapted to be removably connected to a pressure fluctuating segment of the engine. Means is provided which coacts with the fitting and the housing second section and releasably retains the housing and diaphragm in a selected position of adjustment relative to the fitting.
