Abstract
A multiplex injector system comprising an injector head, a first fuel path located in the injector head, and a first set of injector tips located in the injector head and in fluid communication with the first fuel path. The first set of injector tips includes at least one first injector tip. The multiplex injector further includes a second fuel path located in the injector head and a second set of injector tips located in the injector head and in fluid communication with the second fuel path. The second set of injector tips includes at least one second injector tip. A flow of fuel in each of the first and second fuel paths can be selectively controlled to control the flow of fuel through the first and second sets of injector tips.
Claims53
A multiplex injector system comprising:
- an injector head;
- a first fuel path located in said injector head;
- a first set of injector tips in fluid communication with said first fuel path, said first set of injector tips being directly or indirectly rigidly coupled to said injector head and including at least one first injector tip;
- a second fuel path located in said injector head;
- and
- a second set of injector tips being directly or indirectly rigidly coupled to said injector head and in fluid communication with said second fuel path, said second set of injector tips including at least two second injector tips, wherein a flow of fuel in each of said first and second fuel paths can be selectively controlled to control the flow of fuel through said first and second sets of injector tips.

A method for injecting fuel into a combustion chamber comprising the steps of:
- providing a multiplex injector including an injector head, a first fuel path located in said injector head, a first set of injector tips being directly or indirectly rigidly coupled to said injector head and in fluid communication with said first fuel path, a second fuel path located in said injector head, and a second set of injector tips being directly or indirectly rigidly coupled to said injector head and in fluid communication with said second fuel path, said first set of injector tips including at least one tip and said second set of injector tips including at least two tips;
- and
- selectively causing fuel to flow through said first and second fuel paths such that said fuel is corresponding selectively injected through said first and second set of injector tips into said combustion chamber.
A multiplex injector system comprising:
- an injector head;
- a first fuel path located in said injector head and defined at least partially by a first fuel tube;
- a first set of injector tips located in said injector head and in fluid communication with said first fuel path, said first set of injector tips including at least one first injector tip;
- a second fuel path located in said injector head and defined at least partially by a second fuel tube, wherein said first fuel tube is generally located inside and generally coaxial with said second fuel tube;
- and
- a second set of injector tips located in said injector head and in fluid communication with said second fuel path, said second set of injector tips including at least one second injector tip, wherein a flow of fuel in each of said first and second fuel paths can be selectively controlled to control the flow of fuel through said first and second sets of injector tips.
