Abstract
A body, centrally bored, has a threaded inlet section which threadedly, and adjustably receives a through-bored nozzle. The nozzle has an inner end which intrudes into a transverse passage formed of two, communicating holes formed in the body. The holes ingest fluent material, and the nozzle is selectively locked in a given axial position, in the body, by an internally and externally threaded lock bushing. The bushing threadedly engages an end of the nozzle and is torqued up against the body to hold the nozzle in place.
Claims3
An adjustable eductor, comprising:
- a body which is bored axially for its full length and which has an internally threaded inlet section for motive fluent material, a suction section with a hole of a given area, formed through a sidewall thereof, for ingesting fluent material into said body, a mixing chamber, a diverging-bore discharge section, and a centrally axially bored nozzle adjustably positionable within said body by means of external threads which engage the threads of the inlet section to provide means for setting the extent of nozzle advancement into, and withdrawal from said suction section, for establishing a rate of ingestion of fluent material through said hole optimized for the viscosity of the fluent material to be ingested, by varying the degree of intrusion of said nozzle across the area of said hole and thereby adjusting the ingestion effectiveness of said hole area.
An adjustable eductor, comprising:
- a body which has an inlet section, a suction section which has an opposed pair of holes formed through its walls which open onto opposite sides of said body, to define a transverse passage into said body for ingesting fluent material into said suction section, a mixing, section, a diverging-bore discharge section, and
- a nozzle axially positionable within said body;
- wherein
- said nozzle comprises means for selectively varying intrusion into, and withdrawal from said passage, for establishing a rate of ingestion of fluent material of a given viscosity through said opposed holes.
