Nozzle assembly with rotating nozzle insert

A nozzle assembly having a side loading nozzle, said nozzle assembly comprising:

• a nozzle body comprising a flow passage along a longitudinal flow axis of said nozzle body from a fluid input at a first end of said nozzle body to a fluid output at a second end of said nozzle body, said nozzle body comprising a face and defining a nozzle body bore formed in said nozzle body extending from said face through said nozzle body and intersecting said flow passage in a generally perpendicular orientation to said flow passage, said nozzle body bore defined by a substantially cylindrical wall within said nozzle body;
• a nozzle insert removably positioned within said bore in said nozzle body, said nozzle insert comprising an elongated insert body having an insert axis about which said nozzle insert rotates within said insert body, wherein said nozzle insert is rotatable to plural operating positions, said nozzle insert comprising a forward end face comprising a turning knob, wherein a nozzle bore extends through said insert body on an axis intersecting said insert axis, wherein said nozzle bore comprising a first end and a second end and configured to restrict fluid flow therethrough from said first end to said second end, wherein said nozzle bore is configured to align with said flow passage of said nozzle body to provide a continuous fluid passage;
• at least one releasable detent and at least one detent notch, wherein one of said releasable detent or said at least one detent notch is positioned on a circumference of said nozzle insert, wherein the other of said at least one releasable detent is positioned on said nozzle body, wherein said releasable detent is biased to index said nozzle insert at said at least one detent notch, wherein said releasable detent is configured to be released to allow rotation of said nozzle insert, wherein said at least one detent notch corresponds to an operating position.
