Abstract
A straight flow nozzle is provided having a housing through which fluid flows in a straight line, the housing having two opposite ends, one of said ends having a discharge port open to the ambient atmosphere for discharge of the fluid, a coupling means secured to the other end for coupling a source of pressurized fluid to the housing, a valve seat located adjacent to the discharge end of the housing, valve closure means operating in combination with the valve seat, the valve closure means being forced into a closed position by the force of the fluid flow through the housing which prevents the flow of fluid out of the discharge port, and control means for opening and closing the valve closure means.
Claims19
A straight flow nozzle comprising:
- a housing through which fluid flows in a straight line,
- the housing having a discharge port open to the ambient atmosphere for discharge of the fluid and an inlet port at opposite ends of the housing,
- a coupling means secured to the inlet port for coupling a source of pressurized fluid to the housing,
- a valve means located within the housing adjacent to the discharge port,
- the valve means containing a valve seat and a closure means operating in combination,
- the valve closure means being forced into a closed position against the valve seat by the force of the fluid within the housing, and
- control means for opening the valve means to allow passage of fluid.
A straight flow nozzle comprising:
- a housing having a bore open at one end to the ambient atmosphere;
- coupling means secured to the housing for coupling a source of pressurized fluid to the bore;
- valve means in the bore adjacent to the one end having closed and open states for selectively opening and closing the one bore end for releasing pressurized fluid received in the bore to the ambient atmosphere through the bore end;
- a trigger coupled to the valve means and housing and having a valve closed position and a range of valve open positions for placing the valve means in a selected open state in accordance with a given trigger position.
