Abstract
PURPOSE: To improve the response of the gas sensor by placing a negative pressure generator, a gas sensor, and a hydraulic-driven negative-pressure check valve in an air vent passage. CONSTITUTION: Air vent passage U extending between the spout of a fueling nozzle and a compressed air source is connected to negative pressure generator 11, and gas sensor Z is placed in sensor chamber 18 opened to the atmosphere. Upstream air path U and downstream air path UN of negative pressure generator 4 are interconnected through bypass air path UL. A valve mechanism comprises, for example, a piston valve 8 with a flange 28, a diaphragm 34, an air introducing hole 30, and a diaphragm chamber 32, and is driven by the hydraulic pressure in the fuel flow path. The valve mechanism is positioned to restrict the flow of compressed air into a bypass path UL while the hydraulic pressure is not acting. It is positioned, on the other hand, to remove the restriction of the flow of compressed air into the bypass path UL while the hydraulic pressure is acting.
