Abstract
A technique is provided for enhancing fluid flow in an outwardly opening nozzle assembly. A flow enhancement assembly is provided adjacent an exit from an outwardly opening poppet to provide desired spray characteristics. The flow enhancement assembly includes converging and diverging passages and a plurality of ports to form a spray.
Claims66
A nozzle comprising:
- an outwardly opening poppet disposed in a conduit, comprising:
- a fluid passage section;
- and
- a head section removably seated against a forward portion of the conduit;
- and
- a spray formation assembly disposed adjacent the forward portion, comprising:
