Abstract
A fuel supply valve for a slurry fuel injector valve, the fuel supply valve comprising: a fuel inlet for fluid communication with a slurry fuel reservoir; a fuel outlet for fluid communication with a nozzle of the fuel injector valve; a pump chamber port for fluid communication with a pump chamber of the fuel injector valve; and a valve gate moveable between a first position, at which the fuel inlet is in fluid communication along a first slurry fuel flow path with the pump chamber port, and a second position, at which the fuel outlet is in fluid communication along a second slurry fuel flow path with the pump chamber port; wherein the valve gate is operable with a valve actuation liquid from an engine.
Claims14
A fuel supply valve for a slurry fuel injector valve, the fuel supply valve comprising:
- a fuel inlet for fluid communication with a slurry fuel reservoir;
- a fuel outlet for fluid communication with a nozzle of the fuel injector valve;
- a pump chamber port for fluid communication with a pump chamber of the fuel injector valve;
- a valve gate moveable between a first position, at which the fuel inlet is in fluid communication along a first slurry fuel flow path with the pump chamber port, and a second position, at which the fuel outlet is in fluid communication along a second slurry fuel flow path with the pump chamber port;
- and
- a valve actuation liquid chamber;
- wherein the valve gate is operable with a valve actuation liquid from an engine;
- wherein the valve actuation liquid is receivable into the valve actuation liquid chamber to exert a force on the valve gate to drive the valve gate between the first and second positions;
- and
- wherein the valve gate blocks a flow path between the valve actuation liquid chamber and the pump chamber port so that the valve actuation liquid chamber is isolated from the pump chamber port.
A fuel supply valve for a slurry fuel injector valve, the fuel supply valve comprising:
- a fuel inlet for fluid communication with a slurry fuel reservoir;
- a fuel outlet for fluid communication with a nozzle of the fuel injector valve;
- a pump chamber port for fluid communication with a pump chamber of the fuel injector valve;
- and
- wherein the fuel supply valve is for selectively coupling the pump chamber port with the fuel outlet or the fuel inlet by the fuel supply valve comprising a valve gate moveable in a valve chamber between a first position, wherein the fuel inlet is in fluid communication along a first slurry fuel flow path with the pump chamber port, and a second position, wherein the fuel outlet is in fluid communication along a second slurry fuel flow path with the pump chamber port;
- wherein the valve gate is arranged to not substantially exert a force opposing a flow of the slurry fuel into the valve chamber when the valve gate moves between the second position and the first position and/or between the first position and the second position.
