Abstract: A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.

Abstract: A fluid absorbing apparatus. The fluid absorbing apparatus includes an absorbing layer having a fluid absorbing material and a protective layer having a number of apertures extending through the protective layer and in fluid communication with the absorbing layer.

Abstract: A pipe union and compound seal has a first pipe member with a central passageway, a sealing surface and a flange with a shoulder. The union has a fastening member adapted to slide around the first pipe member. The fastening member has a matching flange to abut the first pipe member's flange and has threads formed along the inner surface of the fastening member. A second pipe member has a matching central passageway and threads formed along its outer surface to receive and engage the fastening member's threads. The second member has a face opposing the first pipe member's sealing surface with a trough in the face for receiving and retaining the compound seal. The compound seal is positioned in the trough and in a first embodiment has a central spring and a U-shaped outer shell surrounding the spring. The open end of the shell is disposed radially inward so that increased pressure within the central passageways increases the sealing engagement between the shell and the pipe union.
