Abstract
A fuel flow rate measuring device comprising a control rod axially movable in proportion to the rate of flow of air flowing through a suction pipe, a ball disposed in a taper bore and adapted to be moved in the taper bore by the control rod, the taper bore and the ball cooperating with each other to define a clearance which is variable in proportion to the rate of flow of the air, and a pressure regulator provided between a fluid inlet and outlet for keeping constant the fluid pressure difference across the clearance defined by the taper bore and ball.
Claims8
A fuel flow rate measuring device comprising a flow rate measuring section which is composed of a body having a bore whose cross-section is not uniform in the longitudinal direction, a fuel inlet communicating with said bore and a fuel outlet communicating with said bore, and a ball placed in said bore;
- a control rod, the clearance between said bore and ball being adjustable in accordance with an axial movement of said control rod;
- and a pressure regulator communicating with said fuel inlet and outlet for keeping constant the pressure difference between said inlet and outlet sides, the arrangement being such that the axial position of said control rod and the rate of flow of the fuel correspond to each other in a fixed relation.
