Abstract
An electromagnetically actuatable fuel injector for a linear engine includes a portioning chamber having inlet and outlet valves biased into closed positions and an armature is biased to open the inlet valve. An electromagnetic coil is energizable for moving the plunger in a direction out of engagement with the inlet valve and into engagement with the outlet valve for supplying a metered amount of fuel to the linear engine.
Claims34
A gaseous fuel injector for a linear engine comprising
- a portioning chamber,
- an inlet valve for regulating an admission of gaseous fuel into the portioning chamber,
- an outlet valve for regulating a discharge of gaseous fuel from the portioning chamber,
- each of the inlet and outlet valves being biased toward one of an open and closed position,
- a field-sensitive plunger being moveable within the portioning chamber in directions that alter the open and closed positions the inlet and outlet valves,
- the field-sensitive plunger being movable in a first direction at which the inlet valve is opened for admitting pressurized fuel into the portioning chamber, and
- the field-sensitive plunger being moveable in a second direction at which the outlet valve is opened for discharging the pressurized fuel from the portioning chamber.

An electromagnetically controlled gaseous fuel injector for a linear engine comprising
- a portioning chamber having an inlet regulated by an inlet valve and outlet regulated by an outlet valve,
- an armature movable within the portioning chamber under the influence of an externally applied field,
- the armature together with the inlet and outlet valves being biased into positions at which the inlet valve is open and the outlet valve is closed for charging the portioning chamber with a volume of gaseous fuel, and
- the armature being movable from the biased position at which the inlet valve is open and the outlet valve is closed to an activated position at which the inlet valve is closed and the outlet valve is open for discharging the volume of gaseous fuel from the portioning chamber.
1 more element
An in-line gaseous fuel injector for a linear engine comprising
- a portioning chamber,
- an inlet valve at one end of the portioning chamber for connecting the portioning chamber to a pressurized fuel supply,
- an outlet valve at another end of the portioning chamber for connecting the portioning chamber to the linear engine,
- the inlet and outlet valves being biased toward closed positions,
- an armature moveable within the portioning chamber between positions of engagement with the inlet and outlet valves,
- the armature being biased into a first position at which the inlet valve is open and the outlet valve is closed for filling the portioning chamber with pressurized fuel, and
- an electromagnetic actuator being energizable for moving the armature into a second position at which the inlet valve is closed and the outlet valve is open for discharging the pressurized fuel into the engine.
