Abstract
A self-priming underwater device for generating a vortex ring entrained with a fluid, includes a handle, a housing including front and rear sections, a trigger for supplying a fluid to the housing, a piston assembly in the rear section of the housing and including a yoke, a piston movable in the yoke, and a plate for displacing a liquid, and a splitter for diverting one portion of the fluid to the piston assembly to thereby move the piston. The front section of the housing includes an opening for discharging a vortex ring therefrom, and a fluid supply member is positioned adjacent the opening for supplying another portion of the fluid to be entrained in the vortex ring.
Claims22
An underwater device for generating a vortex ring entrained with a fluid, comprising:
- a) a handle;
- b) a housing including front and rear sections;
- c) a trigger for supplying a fluid to said housing;
- d) a piston assembly in said rear section of said housing and including a yoke, a piston movable in said yoke, and a plate for displacing a liquid;
- e) a splitter for diverting one portion of the fluid to said piston assembly to thereby move said piston;
- f) said front section of said housing including an opening for discharging a vortex ring therefrom;
- and
- g) a fluid supply member positioned adjacent said opening for supplying another portion of the fluid to be entrained in the vortex ring.
A hand-held underwater device for shooting a vortex ring entrained with a fluid, comprising:
- a) a handle;
- b) a housing extending substantially rectilinearly with said handle and including front and rear sections;
- c) a trigger for supplying a fluid to said housing;
- d) a piston assembly in said rear section of said housing and including a yoke, a piston movable in said yoke, and a plate for displacing a liquid;
- e) a splitter for diverting one portion of the fluid to said piston assembly to thereby move said piston;
- f) said front section of said housing including an opening for discharging a vortex ring therefrom;
- g) a fluid supply member positioned adjacent said opening for supplying another portion of the fluid to be entrained in the vortex ring;
- h) a wall between said handle and said housing and including a first surface facing said housing and a second surface facing said handle;
- i) said yoke being disposed on said first surface and including a port through which said piston moves;
- and
- j) a generally circular recess defined by said yoke and the inside of said housing.
