Abstract
A fuel dispensing nozzle for gasoline fuel pumping stations and the like has an inlet through which the fuel is supplied within a range of supply inlet pressures, an outlet from which fuel is discharged and a flow passage having valving for selectively opening communication between the inlet and the outlet. At least one turbulence generating body is located in the flow passage between the inlet and the outlet and a turbulence damping or laminar flow inducing member is disposed in the flow passage upstream from the turbulence generating body member. The turbulence damping body member ensures that substantially laminar flow is directed to the turbulence generating member which thereby may predictably limit the rate of fuel flow through the nozzle to a predetermined maximum rate independent of the fuel inlet pressure within the supply range and independent of the amount of communication provided between the inlet and the outlet by the valving.
