ABSTRACT:
A pressure regulating nozzle that may be incorporated within a fluid supplying device such as a fuel injector. The nozzle or spray tip comprises a reciprocating piston adapted to move a plunger which is slidably located within an outlet bore. The piston further contains a plurality of control orifices located within a bottom portion to provide a controlled pressure drop thereacross to regulate the pressure within the nozzle at a relatively constant value. The nozzle further includes a series orifice, located between the piston and the fluid supply for isolating the piston from upstream pressure surges and to develop rate feedback forces to damp the motion of the piston. In one embodiment of the invention the spray tip includes a plurality of outlet orifices located in fluid communication with the outlet bore wherein the open area of the outlet orifices is modulated by the movement of the plunger in response to the reciprocating motion of the piston. A further embodiment illustrates a by-pass pressure regulator incorporating featues of the present invention.
