Abstract
Abstract This invention relates to apparatus for metering the supply of natural gas to an internal combustion engine having an air intake manifold and throttle valve mounted therein comprising: a pressure regulator for regulating the pressure of said natural gas; a sensor plate associated with said air intake manifold and moveable in response to variations in said throttle; and a valve being actuable by said moveable sensor plate to vary the supply of natural gas to said air intake manifold in response to variations in said throttle valve so as to meter the supply of natural gas to said internal combustion engine.

Claim 2
Dependent Claim
101 words
Apparatus for metering the supply of natural gas to an internal combustion engine having an air intake manifold and throttle valve mounted therein comprising: (a) pressure regulator means for regulating the pressure of said natural gas; (b) sensor plate means associated with said air intake manifold and moveable in response to variations in said throttle valve; (c) valve means being actuable by said moveable sensor plate means to vary the supply of natural gas to said air intake manifold in response to variations in said throttle valve so as to meter the supply of natural gas to said internal combustion engine.
Claim 3
Dependent Claim
69 words
Apparatus as claimed in claim 1 wherein said sensor plate means includes arm means associated with said air intake manifold, said arm means disposed for pivotable movement about one end thereof, and said other end of said arm means including a sensor plate whereby said sensor plate and said arm means pivotly move about said one end of said arm means in response to variations in said throttle valve.
Claim 4
Dependent Claim
20 words
