Abstract

PURPOSE:To always properly release vaporized fuel by mounting two kinds of valves to be parallelly interposed in an evaporating passage, which guides the vaporized fuel from a fuel tank to a canister, and selectively opening each valve in accordance with a rise of pressure in the fuel tank. CONSTITUTION:A valve device 10 is mounted interposing halfway an evaporating passage which introduces vaporized fuel, separated in a gas-liquid separator communicating with upper part space in a fuel tank, to a canister. Here the valve device 10 is constituted mounting two positive pressure valves 12, 13 and one negative pressure valve 14 to be interposed in a valve body 11 respectively in parallel with the evaporating passage. And urging each valve unit 19, 16 by tension of each spring 20, 17, that is, each positive pressure valve 12, 13 respectively opens each valve unit 19, 16, generating a pressure to be different from each other when the evaporating passage is opened. That is, the second positive pressure valve 13 is set larger in its opening passage area and opening pressure than that in the first positive pressure valve 12.
