초록 ▼

A solenoid-operated injector for an electronically controlled fuel oil injection system which serves to control fuel oil injection by means of a shift of a ball valve unit. The ball valve unit includes a flat armature and a ball valve, the flat armature is shifted, floatingly, without any guidance. As the ball valve unit is sucked and moved to an open state, the flat armature abuts against a thin plate having a high magnetic resistance. The top of the flat armature is acted upon by a compressed spring with the top end of the compressed spring abutting against a spring regulating tube, so that the spring force acting on the flat armature can be changed by adjusting the spring regulating tube. Both the compressed spring and ball valve are located in the magnetic stator of the solenoid coil with the flat armature and the ball valve being located such that the spring force normally biases the ball valve against the oblique cone concave on the top of the valve seat.

대표청구항 ▼

A fuel injector for a gasoline engine comprising: a magnetic housing having a leading end, a rear end, a central hole connecting said leading and rear ends and a shoulder portion disposed within said central hole between said leading and rear ends, wherein said housing is made of a soft magnetic material and said rear end is in communication with a pressurized fuel supply; a magnetic coil assembly disposed within said magnetic housing central hole at the rear end of said housing, wherein said magnetic coil includes a central hole disposed coaxially with the magnetic housing central hole; a magnetic stator assembly disposed within the central hole of said coil assembly; a valve seat member having a hollow formed in a concave rear face and having an oblique cone leading to an injection nozzle disposed at a centermost portion thereof, disposed within the housing central hole at the leading end of said housing; screw block means for securing said valve seat member rear face tightly against said shoulder portion of said housing; a ball valve assembly disposed within said hollow formed in said valve seat member and having a semi-circular ball at a leading end and a flat armature at a rear end; a nonmagnetic plate interposed between said housing shoulder portion and said valve seat member; and spring means biasing said ball valve assembly against said valve seat member whereby said semi-circular ball normally seats against said valve seat member oblique cone in a closed condition; wherein said ball valve assembly is moveable to an open position in response to energization of said magnetic coil assembly whereby said pressurized fuel flows from said housing rear end, past said ball valve assembly, through said valve seat member oblique cone and through said injection nozzle.
