Title:
INJECTION VALVE
Document Type and Number:
Japanese Patent JPS5920562
Kind Code:
A
Abstract:
An injection valve for fuel injection devices for internal combustion engines which serves to inject fuel into the intake pipe. The injection valve consists of a valve body with a valve seat cooperating with the sealing part of a valve needle. The valve needle is guided by guide sections in a guide bore of the valve body. The guide section immediately adjoining the sealing part simultaneously serves as a metering section for metering the fuel. For this purpose axially extending surfaces are disposed on the metering section, which form throttling metering openings together with the guide bore. By metering the fuel upstream from the valve seat, impairment of the fuel metering because of deposits formed by reaction of harmful materials from the intake pipe is avoided.
