<p>PURPOSE: A fluid injecting apparatus is provided to reduce delay time between activation and reaction thereof and reduce the response time thereof since magnetic flux passes through magnetic resistive element twice. CONSTITUTION: A fluid injecting apparatus comprises a housing(8), a valve needle(12), an armature(14), and a magneto resistive element(42). The housing comprises a coil(34) arranged with in a hollow. The valve needle axially moves along the preset axis line(L) of the fluid injecting apparatus. The armature axially moves along the preset axis line of the fluid injecting apparatus. The armature is mechanically coupled with the valve needle. The magnetic resistive element is designed to have transmittance smaller than the transmittance of the housing.</p> |
