Abstract
Abstract A method and apparatus for ejecting fluids through use of a high pressure liquid motive fluid by forming hydraulic slugs from said motive fluid and conducting it through conventional ejection mechanisms, entraining a fluid which is to be ejected and depositing it into containment of user's choice. A pulser apparatus is employed which embodies the concept of abruptly starting and stopping high pressure motive flow, contemporaneously constricting the downstream flow through use of either inlet or instream interruption means, and entraining quanta of fluid to be ejected, said entrainment being the urging of said discrete quanta by the momentum of a series of hydraulic slugs formed by the aforementioned method.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
181 words
A fluid ejector comprising: a body having an essentially cylindrical chamber therethrough for the purpose of transporting therethrough a motive fluid and a fluid which is to be ejected and further comprising an inlet chamber having a plurality of opposing apertures, a suction chamber having an induction port and an ejector chamber therein; a source of high pressure liquid fluid for induction into said inlet chamber said source physically enveloping the apertures of said inlet chamber; a means contained by said inlet chamber for pulsing said motive fluid prior to its passage into said suction chamber, said means further comprising a rotating cylinder having apertures which periodically align with said apertures of said inlet chamber, whereby said high pressure motive fluid when inducted into said inlet chamber is caused to form hydraulic slugs which travel through said inlet chamber, through said suction chamber and thence into and through said ejector chamber, entering and capturing quanta of fluid to be ejected which enters at said induction port from said suction chamber and, by their momentum, carrying said quanta through said ejector chamber.
Claim 2
Dependent Claim
181 words
A fluid ejector comprising: a body having an essentially cylindrical chamber therethrough for the purpose of transporting therethrough a motive fluid and a fluid which is to be ejected and further comprising an inlet chamber having a plurality of opposing apertures, a suction chamber having an induction port and an ejector chamber therein; a source of high pressure liquid fluid for induction into said inlet chamber said source physically enveloping the apertures of said inlet chamber; a means contained by said inlet chamber for pulsing said motive fluid prior to its passage into said suction chamber, said means further comprising a rotating cylinder having apertures which periodically align with said apertures of said inlet chamber, whereby said high pressure motive fluid when inducted into said inlet chamber is caused to form hydraulic slugs which travel through said inlet chamber, through said suction chamber and thence into and through said ejector chamber, entering and capturing quanta of fluid to be ejected which enters at said induction port from said suction chamber and, by their momentum, carrying said quanta through said ejector chamber.
Claim 3
Dependent Claim
63 words
The invention of claim 1 wherein said pulsing means further comprises a motivated rotating apertured tubular cylinder longitudinally mounted with respect to said body and within said inlet chamber, whereby the apertures of said tubular cylinder are intermittently in and out of registry with the apertures of said inlet chamber and effect induction of said high pressure fluid in a repeated pulsing fashion.
