|20130153051||ROLL OVER VALVE - A valve for a fuel tank comprising a housing configured with a float chamber and a disk chamber being in flow communication through an intermediate flow path. The float chamber configured with a valve inlet which is in fluid communication with the fuel tank and a fluid inlet port into the intermediate flow path. The disk chamber configured with a fluid outlet port from said intermediate flow path and a valve outlet and the fluid inlet port is sealable by a sealing member of a float member axially displaceable within the float chamber to selectively facilitate fluid flow to or from the float chamber via the valve, and the fluid outlet port is sealable by a pressure holding member axially displaceable within the disk chamber to selectively facilitate fluid flow into or out of said fluid outlet port. The pressure holding member configured with an under pressure bleed valve displaceable between a sealed position wherein the under pressure bleed valve is sealed, and an open position wherein the under pressure bleed valve is open, providing passage of fluid therethrough.||06-20-2013|
|20100139625||VEHICLE FUEL SYSTEM AND COMPONENTS THEREOF - A fuel vapor control valve comprising a housing. The housing comprising inlet and outlet ports in flow communication via first and second valve controlled passages. The first valve controlled passage being configured to admit fuel vapor flow in a direction from the inlet port to the outlet port only when pressure at the inlet port exceeds a predetermined threshold. The second valve controlled passage being configured to admit vapor flow in a direction from the outlet port to the inlet port only when pressure at the inlet port drops below pressure at the outlet port. The fuel vapor control valve further comprising a sealing arrangement disposed at an external portion of the housing between the inlet and outlet ports.||06-10-2010|
