Abstract
A pair of liquid flow passages are formed in a chamber and liquid flow through the passages is alternately blocked and unblocked by alternately pulsating vortices which causes alternate pulsations of fluid flow through the pairs of liquid flow passages.
Claims2
A liquid oscillator comprising,
- a chamber,
- liquid inlet means for introducing liquid under pressure into said chamber,
- liquid outlet means for forming an outlet from said chamber to ambient,
- means forming a pair of parallel liquid passageways in said chamber between said liquid inlet means and said liquid outlet means,
- means in said chamber to create alternately pulsating vortices which increase and decrease in strength, associated with said parallel liquid passageways, respectively, which alternately block and pass fluid flow through said pair of liquid passageways with the increasing and reducing strength of said vortices causing pulsating fluid flows through said passageways, respectively.
2 more elements
A method for producing alternately pulsating first and second liquid streams, each said liquid stream being of varying liquid flow rate and of different phase, respectively, comprising,
- providing liquid flow through a pair of parallel liquid flow passageways from a common source to a common liquid outlet, and,
- inducing alternately pulsating vortices for rythmically and alternately blocking and unblocking, respectively, liquid flow through said pair of liquid passageways to said common outlet.
