Abstract:
1. An apparatus for a gaseous fuel injection system including: (i) A first chamber including an inlet connectable with a source of gaseous fuel at a required inlet pressure; (ii) A second chamber connectable with an engine or other apparatus so as to supply gaseous fuel thereto and further connected with said first chamber through a controllable valving means; (iii) A flow control means having an inlet connectable with said first chamber and an outlet connectable with an orifice means for controlling the pressure at the outlet of said flow control means to be no more than 53% of the inlet pressure; (iv) Detection means for detecting said outlet pressure and controlling said valving means; (v) The arrangement being such that controlling the said flow control means to adjust the flow of gaseous fuel therethrough controls the said outlet pressure which in turn controls said controllable valving means and the pressure in said second chamber, so as to thereby control the flow of gaseous fuel to said engine or other apparatus.
