A fuel injector has a silicon micromachined nozzle plate which coacts with a fuel flow valve to control fuel flow out of the fuel injector.

Fuel injector with silicon nozzle

A silicon compound nozzle has two generally planar parallel plates with offset openings coupled by a shear gap. Fluid flow in the shear gap is generally parallel to the plates and increases fluid dispersion.

Silicon micromachined compound nozzle

A valve assembly for controlling fluid flow includes a valve plate and a nozzle plate which are not attached to each other but can be moved into and out of contact with each other. The valve plate has an opening for passing an actuator and fluid. A nozzle plate has an opening for passing fluid and the opening is aligned with a mesa on the valve plate which can seal the nozzle orifice. The actuator separates the nozzle plate from the valve plate to permit fluid flow and a spring means brings the nozzle plate into a closed position against the valve plate to stop fluid flow.
