Title:
ELECTROMAGNETIC TYPE FUEL INJECTION VALVE
Document Type and Number:
Japanese Patent JPH04358763
Kind Code:
A
Abstract:

PURPOSE: To provide an electromagnetic type fuel injection valve excellent in corrosion resistance and responsiveness at the time of opening/closing a valve, easy in processing, and manufacturable inexpensively.

CONSTITUTION: A reciprocating needle valve 8 is guided, movably in a shaft direction, to a guide hole 7 of a valve main body 2. The valve main body 2 has a valve seat part 6 on which the needle valve 8 can abut and a nozzle 5. When an electromagnetic coil 26 is electrified, the needle valve 8 is moved to a fixed iron core 25 side in a valve-opening direction by electromagnetic attracting force against a returning coil spring 28. A cylindrical housing 50, housing the electromagnetic coil 26, has a slit 50a so as to be nonconductive in the peripheral direction of the housing 50, and is formed by cylindrically bending a plate material. This restrains the generation of overcurrent, improving responsiveness at the time of valve opening/closing action by strong electromagnetic attracting force.
