摘要： An electromagnetically actuatable valve is proposed that serves in particular as a fuel injection valve for fuel injection systems of internal combustion engines. An armature cooperates with magnet poles, and a bearing cone the length of the generatrix of which is approximately equivalent to the diameter is machined into a valve seat body. The armature and valve seat body may also have bearing faces of calotte shape facing one another.

摘要： 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.

摘要： An electrmagnetic intermittent injection valve for supplying fuel to an intake duct of an internal combustion engine comprising a hollow body having a fuel inlet for admission of fuel from a fuel supply, a fuel outlet for supply of fuel to an intake duct of an internal combustion engine, and a fuel return for returning fuel back to the fuel supply. A ball valve is movable in the body between a first position in which the fuel outlet is closed and a second position in which the fuel outlet is open. A spring acts on the ball to urge the ball to the first position. A soft iron core is disposed in the body in facing relation with the ball, the body including a housing end portion of soft iron facing the ball valve. A coil in the body serves for energizing the core and the housing end portion for producing a magnetic field having lines of flux acting on the ball valve to urge the ball valve to the second position against the resilient opposition of the spring. The core and housing end portion are arranged in relation to the ball valve such that the lines of flux produced by the housing end portion form an angle therebetween less than 90.degree..

摘要： A fuel injector valve for use in an internal combustion engine has a spherical valve member which is movable to be biased onto a valve seat by pressure differential between upstream and downstream sides of the valve member. A pressure responsive element is disposed within the electromagnetic valve and located opposite to the valve member in order to bias the valve member against the valve seat to close a fuel outlet when fuel pressure prevailing upstream of the valve member is lower than a predetermined level.

摘要： A ball valve electromagnetic fuel injector includes a spring biased low-mass magnetic ball which oscillates with respect to a conical valve seat in the injector case to open and close the fuel supply. A solenoid having a stationary pole piece with a spherical tip recess provides a uniform attractive force in pulling the ball away from the valve seat to the open position in accordance with a fuel metering schedule.

摘要： Fuel injector nozzles are described including electromagnetically-operable interrupter valves whereby the nozzles can be operated to discharge fuel intermittently. In one form, the movable valve member of the interrupter valve is spherical. In another form, a through-flow fuel path is provided to permit the continuous circulation of fuel through the nozzle even when the interrupter valve is closed, and a vapor separating path is provided to remove fuel vapor. In yet another form, a non-magnetizable element is provided to reduce operating delays in the interrupter valve as a result of residual magnetism.
