Regulation and adjustment of the rates of flow of liquid

Claim 1

A DEVICE FOR REGULATING THE FLOW OF A FLUID, IN PARTICULAR A FLOW OF FUEL SUPPLIED TO A COMBUSTION MACHINE, AS A FUNCTION OF A PARAMETER, COMPRISING A CYLINDER BODY, A PISTON-REGULATOR SLIDABLY MOUNTED IN THE CYLINDER BODY SO AS TO DEFINE IN SAID CYLINDER A FIRST CHAMBER AND A SECOND CHAMBER, DOSING SLOTS CUT IN THE WALL OF THE CYLINDER BOXY, SAID DOSING SLOTS OPENING IN THE FIRST CHAMBER AND BEING SO ARRANGED AS TO TBE MORE OR LESS UNCOVERED BY THE PISTON-REGULATOR SLIDING IN THE CYLINDER, MEANS FOR FEEDING THE FLUID INTO SAID FIRST CHEMBER THROUGH SAID DOSING SLOTS AND INTO SAID SECOND CHAMBER, OUTLET PORTS CUT IN THE WALL OF THE FIRST CHAMBER, SO THAT THE FLUID MAY FLOW THROUGH SAID DOSING SLOTS, SAID FIRST CHAMBER AND SAID OUTLET PORTS, A FEELERR MEMBER BOUND PHYSICALLY WITH THE PISTON-REGULAR SO AS TO FOLLOW ITS SLIDING MOVEMENT, A NOZZLE CARRIED BY SAID FEELER MEMBER AND COMMUNICATING WITH THE SECOND CHAMBER, A CAM MEMBER THE POSITION OF WHICH IS FUNCTION OF THE PARAMETER AND A BALL LODGED IN THE FEELER MEMBER, SAID BALL BEING APPLIED AGAINST THE CAM MEMBER AND SERVING DIRECTLY AS A REGULATING VALVE TO PERMIT VENTING OF FLUID IN SAID SECOND CHAMBER THROUGH THE NOZZLE, BY BEING MORE OR LESS APPLIED AGAINST SAID NOZZLE.

Claim 2

A DEVICE FOR REGULATING THE FLOW OF A FLUID, IN PARTICULAR A FLOW OF FUEL SUPPLIED TO A COMBUSTION MACHINE, AS A FUNCTION OF A PARAMETER, COMPRISING A CYLINDER BODY, A PISTON-REGULATOR SLIDABLY MOUNTED IN THE CYLINDER BODY SO AS TO DEFINE IN SAID CYLINDER A FIRST CHAMBER AND A SECOND CHAMBER, DOSING SLOTS CUT IN THE WALL OF THE CYLINDER BOXY, SAID DOSING SLOTS OPENING IN THE FIRST CHAMBER AND BEING SO ARRANGED AS TO TBE MORE OR LESS UNCOVERED BY THE PISTON-REGULATOR SLIDING IN THE CYLINDER, MEANS FOR FEEDING THE FLUID INTO SAID FIRST CHEMBER THROUGH SAID DOSING SLOTS AND INTO SAID SECOND CHAMBER, OUTLET PORTS CUT IN THE WALL OF THE FIRST CHAMBER, SO THAT THE FLUID MAY FLOW THROUGH SAID DOSING SLOTS, SAID FIRST CHAMBER AND SAID OUTLET PORTS, A FEELERR MEMBER BOUND PHYSICALLY WITH THE PISTON-REGULAR SO AS TO FOLLOW ITS SLIDING MOVEMENT, A NOZZLE CARRIED BY SAID FEELER MEMBER AND COMMUNICATING WITH THE SECOND CHAMBER, A CAM MEMBER THE POSITION OF WHICH IS FUNCTION OF THE PARAMETER AND A BALL LODGED IN THE FEELER MEMBER, SAID BALL BEING APPLIED AGAINST THE CAM MEMBER AND SERVING DIRECTLY AS A REGULATING VALVE TO PERMIT VENTING OF FLUID IN SAID SECOND CHAMBER THROUGH THE NOZZLE, BY BEING MORE OR LESS APPLIED AGAINST SAID NOZZLE.
