  • Patent number: 10175068
    Abstract: Disclosed is a pressure compensator for a housing compartment that includes a housing wall that has an opening between an interior zone that is inside of the compartment and an exterior zone that is outside of the compartment. The housing wall also includes an annulus that defines one portion of the opening. A seal engages the annulus and is seated in the opening to seal the opening, the seal including a flexible diaphragm having a normally closed slit therethrough. The seal is configured so that the diaphragm is normally compressed in a first direction that urges the slit closed when the seal is engaged with the annulus. The diaphragm is arranged so that a pressure difference between the interior zone and exterior zone urges the diaphragm to flex in a direction for opening a slit thus creates a pathway between the interior zone and the exterior zone, thereby reducing the pressure difference.

  • Patent number: 6871640
    Abstract: A fuel delivery system including a fuel tank having multiple sections. A fuel pump is disposed in a first section with an inlet for drawing liquid fuel from the first section and an outlet for supplying the fuel to an engine and to a pick-up disposed in the second section. A siphon line is connected to the pick-up at one end and terminates in the first section at another end. A fuel inlet of the pickup communicates with the siphon line through a valve member that is actuated to open and closed positions. In operation, the fuel pump provides a flow of liquid fuel to the pick-up to purge and prime the siphon line which normally maintains a substantially equal liquid fuel level in the first and second sections of the fuel tank. In some conditions, the valve closes to prevent reverse flow of fuel from the first section to the second section of the tank.
