Abstract
A poppet valve device is composed such that a plurality of axial passages of substantially the same diameter and length communicating to a high-pressure space formed inside the valve seat member between the poppet valve body and the valve seat member are provided in the valve seat member. The passages are located adjacent to each other, or located axially symmetrically. An annular gap formed between the periphery of the poppet valve body and the inner perimeter of a projecting part on which the valve seat face of the valve seat member is formed is narrow to restrict liquid flow through the annular gap. An electronic controlled fuel injection apparatus equipped with the poppet valve device is composed such that a lower end part of the poppet valve body and the bottom of a valve device accommodating part of the fuel injection apparatus are formed to restrict the flow of fuel from between the lower end of the poppet valve body and the bottom of the valve device accommodation part to the central hollow of the poppet valve body, whereby the occurrence of bouncing is prevented.
