Abstract: A fuel conditioning system (10) comprises a housing (12) defining a chamber (14) and provided with an inlet (16) upstream of the chamber (14) and an outlet (18) downstream of the chamber (14). A hemispherical seat (20) is formed in the housing (10) with a first end (22) in communication with the inlet (16), and a second end (24) in communication with the chamber (14). A valve body (26) is received within the seat (20) and is moveable between a closed position and an open position where the valve body is spaced from the inlet (16) to allow air to flow into the chamber (14). A spring (32) biases a valve body at a pressure of approximately one atmosphere toward the closed position. Fuel is sprayed from a plurality of jets (72) formed in the seat and laterally relative to the flow of air past the valve body.

Abstract: A fuel conditioning system 10 comprises a housing 12 defining a chamber 14 and provided with an inlet 16 upstream of the chamber 14 and an outlet 18 downstream of the chamber 14. A hemispherical seat 20 is formed in the housing 10 with a first end 22 in communication with the inlet 16, and a second end 24 in communication with the chamber 14. A valve body 26 is received within the seat 20 and comprises a curved surface 28 and a planar surface 30 that extends across the curved surface 28. The valve body 26 is moveable between a closed position where the valve body 26 seals the inlet 16 and an open position where the valve body is spaced from the inlet 16 to allow air to flow through the first end 22 between the seat 20 and curved surface 28, and through a gap 38 formed between the second end 24 and an adjacent portion of the valve body 26, into the chamber 14. A spring 32 biases a valve body at a pressure of approximately one atmosphere toward the closed position.
