1LUID TRANSLAT Original application filed September 14., 19
To all whom it may co-ncevw:
Be it known that I, HENRY F. EECHMHYZ; The no. i a citizen of the United States, ani dischuige' dent of SWui't-hinore, in the county of i ehi tion. '10 c Ware and State of Pennsylvania, have 'iiii vented a new and useful improvement in Fluid-Translating Devices, of which the foilowing is a specification, this appiioation being a division of my application Selma No. 861.683, filed Sept. 14:,
1914:. This invention relates to A1116. tifinSiflilZlg devices and particularly to e ector zip rows for maintaining a high vacuum in condens- ..o the oior ers or silniizir apparatus. hioh is ieiescopicaiiy 0 An ObJQO'iZ of the invention is to pro head shows duce a fluid ejecting device of the i etio type in which new and improved means employed for maintaining the operation of the device substantially constan preoticaiiy all varying conditions.

The 618C601 illustrated CGXiSiSiE esseiitie of a ciifiuser 2 of any desired "form, ing chamber 3, and s. piuraiity of fluid delivery nozzles, located. in. the chamber and movable toward from the iniet of the diffuser $01 the Billpose of stabiliziir the operation 0 the ejector under vazylngoperetiilg CGTlCiiiliO'alS, or under varying conditions oi flow of the medium to be'expeiied. In the sppsm illustrated the automaiio means pioyed for varying the position of the nozzles with relation to the difi'usei' in response to variations in pressure conditions 1 within the ejector.
In the drawings, 1 have iii'usiaiod a rangement of nozzles, which mum is to the pressure within the chamber 3, that 'the medium from the chamber 3 is always v Under normal pressure conditions Within the chamber 3, the combined nozzle occupies a position approximately as shown in the drawin and both the accelerating nozzles 5 and t e main nozzle 4 are effective in entraining and moving the medium from the chamber 3 through the diffuser. As the pressure of the chamber 3 decreases, the combined nozzle moves toward the throat of the diffuser, and, at some predetermined pressure, as when there is little or no medium within the chamber 3 to be expelled, the combined nozzle moves to such position as to close the gap between it and the diffuser. Under such conditions the fluid discharged from the accelerating nozzles acts only as a filler for the diffuser 2, and the nozzle 4: is alone effective in maintaining a low absolute pressure within the chamber 3. As the pressure within the :chamber 3 increases, the combined nozzle inlet of the diffuser.
While I have shown my invention in but one form, it will be obvious to those skilled in the art that, it is not so limited but is susceptible of 'various other changes and modifications," without departing from the spirit thereof and I desire, -therefore, that only such limitationsshall be placed thereupon asare imposed by the prior art or as are specifically set forth in the appended claims.
What I claim is 2-- 1. In combination, achamber for fluid to be translated, a diffuser communicating therewith, and a series of motive fluid nozzles movable to different positions relatively to the diffuser, and means responsive to the amount of fluid in said chamber for varying the effective passage area for fluid to be translated.
2. An ejector comprising a chamber, a diffuser communicating therewith, an element having a. series of nozzles for delivering motive fluid through the diffuser for translating medium contained in the chamber, said element being movable toward and from the inlet of the diffuser to vary the effective inlet area of the latter, and means responsive to the variations in the pressure of medium to be translated for varying the effective inlet area of the diffuser.
3. An ejector comprising a mixing chamber having an inlet for fluid to be translated, a diffuser communicating with the mixing chamber, a'nozzlehead cooperative with the inlet of the diffuser to vary the inlet of the diffuser, means responsive to the pressure of fluid in the mixing chamber to move the nozzle head to vary the inlet area, said nozzle head having a central diffusing nozzle and an annular series of converging diffusing nozzles surrounding and below the central diffusing nozzle, and said head also having ports for fluid to be translated cooperative with the central diffusing nozzle. 4. An ejector comprising a chamber for fluid to be translated, a diffuser communicating therewith, a nozzle head within the chamber having a main motive fluid nozzle and a series of accelerating nozzles located therebelow, a means responsive to the amount of fluid to be translated in said chamber for varying the entraining capacity of the accelerating nozzles.
In testimony whereof, I have hereunto subscribed my name this day of March I HENRY F. SCHMIDT.
