Abstract
Official abstract text for this publication.
A roll over valve for a fuel tank of a vehicle may include a plurality of oil surface variable fuel inflow tubes mounted on an inlet through which fuel is introduced into a float of a single type roll over valve mounted on the fuel tank.
First claim
Opening claim text (preview).
What is claimed is: 1. A roll over valve apparatus for a fuel tank of a vehicle, wherein a plurality of oil surface variable fuel inflow tubes are mounted on an inlet of a housing through which fuel is introduced into a float of a single roll over valve mounted on the fuel tank. 2. The roll over valve apparatus of claim 1 , wherein the inlet through which the fuel is introduced into the float includes a plurality of inlets formed at a regular interval and the oil surface variable fuel inflow tubes are mounted on each inlet. 3. The roll over valve apparatus of claim 1 , wherein the oil surface variable fuel inflow tubes include a first U-shaped tube mounted on an inlet formed at a first side of inlets through which the fuel is introduced into the float and a second U-shaped tube mounted on an inlet formed at a second side. 4. The roll over valve apparatus of claim 1 , wherein the oil surface variable fuel inflow tubes include a first bending tube mounted on an inlet formed at a first side of inlets through which the fuel is introduced into the float and a second bending tube mounted on an inlet formed at a second side. 5. The roll over valve apparatus of claim 1 , wherein the oil surface variable fuel inflow tubes include a first tube mounted on a first inlet among a plurality of inlets through which the fuel is introduced into the float, a second tube mounted on a second inlet, and a third tube mounted on a third inlet. 6. The roll over valve apparatus of claim 5 , wherein the first to third tubes form a concentric array. 7. The roll over valve apparatus of claim 1 , wherein the oil surface variable fuel inflow tubes are inclined downward at an angle of 1 to 5°. 8. The roll over valve apparatus of claim 1 , wherein when the fuel tank is inclined at a predetermined angle or more together with the vehicle, an inlet of the oil surface variable fuel inflow tubes positioned at an upper side of the plurality of oil surface variable fuel inflow tubes becomes a fuel inlet for a reach of a clog point.
