Title: Fuel shut-off valve device
Inventor: KOJIMA TAKESHI
IPC: F16K24/04
Filed: 2002-08-07
Abstract: <P>PROBLEM TO BE SOLVED: To prevent evaporating fuel from being transmitted due to an internal pressure of a fuel tank by enabling the internal pressure of the tank to be maintained in a state close to an atmospheric pressure.  <P>SOLUTION: A fuel shut-off valve device 10 includes a float valve 15 mounted with a housing 11 at a fuel tank 1 side of a vehicle to form a passage for communicating within the tank 1 through an exterior to open or close the passage by a buoyancy of the fuel introduced into the housing 11, and a bidirectional valve 20 provided at an upstream side of the valve 15 to open or close by increasing or decreasing the internal pressure of the tank 1. In the device, the valve 20 opens or closes according to a difference between the internal pressure of the tank 1 and the atmospheric pressure, and one valve (25 and 23) of the bidirectional valve is openable by a vibration when the vehicle travels. According to this, since the valve 20 repeats opening and closing by the vibration when the vehicle travels, air is introduced into and output from the tank 1 at the valve opening time to hold the pressure of the tank 1 in a state near the atmospheric pressure.  <P>COPYRIGHT: (C)2004,JPO
