Fluid switch with reflected shock wave

A fluid switch device in which shockwave energy is utilized to switch the path of a fluid comprising, a fluid input channel means for guiding fluid flow from a fluid source;

• a first fluid output channel means connected with said fluid input channel means for guiding fluid flow from said fluid input channel means;
• a second fluid output channel means connected with said fluid input channel means for guiding fluid flow from said fluid input channel means;
• switching means for selectively directing fluid flow from said fluid input channel means to one of said first and second fluid output channel means, said switching means comprising, a reflector means for reflecting a shockwave, said reflector means comprising a conical surface of revolution having a parabolic base, said surface of revolution defining an opening at its apex, said opening in fluid communication with said fluid input channel means upstream of said first and second fluid output channel means;
• and means for propagating a shockwave comprising an electrical discharge source, said electrical discharge source positioned in said conical surface of revolution between said parabolic base and said opening, wherein said shockwave is reflectable by said reflector means toward said opening.
