<p>PURPOSE: To hold a pressure in a fuel distribution line by a nozzle by providing an extension spiral coil spring wound spirally, and overlapping one end of the coil of the spring with an end part of a tubular member for anchoring the spring to the tubular member. CONSTITUTION: A nozzle 14 is provided with a tubular main body 20 for receiving fuel from a fuel distribution line 12, a tubular seat member 24 is housed in a left end part 22, the seat member 24 is provided with an opening for delivering fuel and a valve seat 28 for enclosing the opening 26. A poppet valve member 30 is engaged with the valve seat 28, flow of fuel is interrupted, the extension spiral spring 32 is anchored to the main body 20 and the valve member 30, and the valve member 30 is biased so as to engage with the valve seat 28. When a pressure difference between both sides of the valve member 30 attains a prescribed value, the valve member 30 is detached and displaced from the valve seat 28, and fuel is delivered to an inlet port of an engine by the nozzle 14. In a right side end part 44 of the spring 32, a plurality of winding part having a large diameter is overlapped with an end part 46 of the main body 20, and the spring 32 is anchored to the valve member 30.</p> |
