ABSTRACT:
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.
