ABSTRACT:
This invention relates to an actuating mechanism for a pump inlet closure valve and includes in combination a pump housing which projects into a fuel tank and has an opening to allow passage of fuel from the tank into the pump housing. A pump inlet closure valve sleeve is positioned within the pump housing and is mounted for movement in a predetermined path. A pump is positioned within the valve sleeve. A fixed pump housing seal is located in the path of the valve sleeve as well as within and between the pump and the housing. A valve actuating mechanism includes a handle which is pivotally secured to the pump housing and slideably moveable in a direction parallel to the path of the valve sleeve. The handle is mechanically coupled to the valve sleeve whereby initial manual movement of the handle causes the valve sleeve to move into a position blocking the opening to the fuel tank. The valve sleeve is locked in place during subsequent pivotal movement of the handle, which movement allows for the unobstructed passage of the pump from the housing.
