Claim:
A valve associated with a fuel tank in which above the level of liquid in the tank is a vapor fluid, said valve comprising a housing defining a control space having intercommunicating ports with an outlet port for fluid egress from said control space, at least one inlet port for fluid ingress into said control space and a liquid draining port; and a displaceable control member displaceable between an open state in which said outlet port is open and a closed state in which said outlet port is closed; the valve characterized in that: the at least one inlet port is formed in an outer lateral wall of the housing, said at least one inlet port being located at an upper part of the outer lateral wall portion, and said fluid draining port is formed at or adjacent a bottom end of the housing for draining fluid from said space, said fluid draining port preventing fluid ingress into the control space; said draining port being closeable by means responsive to the level of fluid in the tank, the arrangement being such that when the level of fluid in the tank is lower than the at least one inlet port, said control member rests on said means responsive to the level of fluid in the tank.
