Velocity compensated poppet valve

Claim 1

A POPPET VALVE COMPRISING MEANS DEFINING A VALVE CHAMBER HAVING A VALVE SEAT, AN INLET CONNECTED TO SAID VALVE SEAT, A POPPET IN SAID CHAMBER HAVING A TAPERED VALVE PORTION, MEANS ACTING AGAINST SAID POPPET TO URGE SAID POPPET TOWARDS A CLOSED POSITION WHEREIN SAID VALVE PORTION IS SEATED AGAINST SAID SEAT, THE PRESSURE OF FLUID IN SAID INLET ACTING AGAINST SAID POPPET TO MOVE SAID VALVE PORTION AWAY FROM SAID SEAT TOWARDS AN OPEN POSITION WHEN SAID PRESSURE EXCEEDS A PREDETERMINED VALUE, THEREBY FORMING A PRIMARY ORIFICE BETWEEN SAID SEAT AND SAID VALVE PORTION, SAID POPPET BEING MOVABLE THROUGH A PREDETERMINED NORMAL RANGE EXTENDING FROM THE CLOSED POSITION TOWARDS THE OPEN POSITION, THE LENGTH OF SID TAPERED PORTION BEING SUCH THAT AT LEAST SOME OF SAID TAPERED PORTION EXTENDS BEYOND SAID SEAT AND INTO SAID INLET WHEN THE POPPET IS IN THE OPEN POSITION, AN OUTLET FROM SAID CHAMBER SPACED FROM SAID VALVE SEAT, SAID POPPET INCLUDING MEANS COOPERATING WITH SAID VALVE CHAMBER AND SAID VALVE PORTION TO FORM A REGULATING CHAMBER INTERMEDIATE SAID INLET AND SAID OUTLET FOR RECEIVING FLUID FROM SAID PRIMARY ORIFICE, MEANS DEFINING A SECONDARY ORIFICE FOR DELIVERING FLUID FROM SAID CHAMBER TO SAID OUTLET, SAID SECONDARY ORIFICE DEFINING MEANS BEING SO CONTRUCTED AND ARRANGED THAT THE SIZE OF SAID SECONDARY ORIFICE REMAINS CONSTANCT AS SAID POPPET MOVES THROUGH SAID RANGE AND IS GREATER THAN THAT OF SAID PRIMARY ORIFICE, WHEREBY THE PRIMARY ORIFICE AT ALL TIMES EXERCISES PRIMARY CONTROL OVER THE MOVEMENT OF THE POPPET THROUGH SAID RANGE, THE PRESSURE OF THE FLUID IN THE REGULATING CHAMBER BEING EFFECTIVE TO ACT UPON SAID POPPET TO MOVE IT AS A FUNCTION OF THE FLOW THROUGH THE SECONDARY ORIFICE IN ORDER TO COMPENSATE FOR INCREASING FLOW RATES BETWEEN THE INLET AND OUTLET.
