Abstract
The well-known "Jack-shaft" or "Single-point" positioning or a two-point parallel combustion control system has been modified by a trim link member articulated on the master arm to introduce a phase angle between the master arm associated with fuel supply adjustment and the slave arm associated with the combustive agent supply adjustment in a combustion engine, boiler, heater, or the like, thereby to permit oxygen or air-to-fuel ratio adjustment at all times.
Claims4
In a combustion apparatus supplied with fuel mixed with an intake of a combustive agent, the combination of:
- a master member having an extremity movably mounted about a first axis for regulating the amount of fuel supplied;
- a slave member having an extremity movably mounted about a second axis for regulating the amount of combustive agent intake;
- a trim member positioned at a selectable angle relative to said master member and about the extremity thereof;
- and
- an intermediate mechanical link connected between said trim member and said slave member for establishing said master-slave relationship through said trim member thereby to establish a fuel-to-combustible agent ratio which is a function of said selectable relative angle.
