ABSTRACT:
A stop valve for use in, for example, a fuel tank bleeding system, has a casing with a valve opening defined in a top portion thereof, a bleeding passage provided downstream of the valve opening, a float provided in a casing for vertical movements, and an elastically deformable valve element disposed on top of the float for closing the valve opening when raised together with the float. The valve element includes a hole extending therethrough. An abutment member is provided in the valve opening for, when the valve element is lifted, abutting a portion of the valve element that surrounds the hole. Optionally, the lower end of the abutment member has a recess. The abutment member may be provided with a member for reducing deformation of the valve element caused by abutment to the abutment member. A fuel splash guard may be provided in the bleeding passage.
