초록

A floating piston (54) has a valved (86) vent opening (88), with the vent opening closing (92) on movement of the piston. The piston is spring loaded (56, 58) to vent air, but seal fuel. Modulation of pressure in pressure resisting chamber (48) between pump discharge and lower pressures, provides control of the valve. Pressure difference (96, 62) and valve position (36) measurements provide flow measurement data.

청구항

A multiple function fuel valve comprising: a valve body having an inlet pressure chamber at one end, a resisting pressure chamber at the other end, and a central piston receiving compartment between said chambers; a piston slidable within said compartment and exposed to said inlet pressure chamber and to said resisting pressure chamber, and having an annular recess between the two ends forming a distribution chamber within said compartment; a first spring between said body and said piston resisting movement of said piston toward said resisting pressure c...
