Jipplication filed August 13, 1922.
To allwhom it may concern:
Be it known thntl, Jozm F. Kine-AN, a citizen of the United States, and a residentof Phillipsburg, county of \Varren, State of New Jersey, have invented a certain Jet Augmeni'zer or Ejecior, or". which the followis a specification, accompanied by drewings.
ejecoors, more particularly for augmenting fluid pressure in any desired apparel-us, such. as a condenser, cooler or similar vessel, by n of fluid jets, in which the fluids are separated into a plurality of separate enveloping layers or strata, which later commingle.
The primary object; of the invention is to simplify and improve the construct-ion of the cu inentei' or ejecicr and to cause the steam to he emit-ted from the nozzle in the form of a hollow cylindrical jet or envelope, so that a large area is provided inside and outside of the or envelope of steam for the en treinnient of the air and other vapors from condenser,
A further object is to construct aring nozzle and diffuser of few 1 ertsaml of such hape that they effective y cooperate with cch other to'cause the steam to be emitted from the nozzle in the form of ring jet or envelope surrounding an inner jet of air and senor, the she-cm jet being itself surrounded by an outer envelope of air or Va pcr, the outer envelope of air lacing surrounded by an enevelope of cooling Water.
Another object is to introduce the cooling Water at a point in the difi'user body, and in a manner, which is most effective for cool ing purposes and to obtain a certain conclensing effect-i Furl-her ohgecis will later appear and to encls set forth in KIRYBIIUOD consist-s in the nozzle end tiomor diffuser A of the ejector is cast or.
oiherwiso constructed in one piece, and as shown is formed with the contracted throsc -B having the enlarged outlet (3' at one end This invention relates to jet auginenters or V e features of construction and operation Serial El'o. 582346.
.of che body, prcfewhly surrounded by the securing flange D which may be provided with securing apertures and fasteningmeans (not. shown) ,hy means which the ejector is secured in position on the desired sepsis: tus with which it is so be used, The inle E of the ejector, for air or other vapor, or bosh, is preferably formed separately from the body and extends at an angle the longitudinal axis of the ejector. ln *chis in stance the inlet, E is shown at right angles to said axis and is provided With the se-- curing flange H, The inlet head is threaded to the enlarged diameter poll/ion .l' of the body A as shown as K.
A nozzle aperture L is provided at the top of the inlet heed G the insertion of s nozzle body 0 in axial alignment wilal she throat B. It is important that the nozzle aperture L shall he concentric wil'h the throat oi: the (liiiuscr for good operuiioni The nozzle body 0 is provided with an externally screw threaded portion. P which is adapted to cooperate with a screw threaded portion. Q of the nozzle speriure L for re Inovably connecting the nozzle body to the head G.
A nut R is preferably formed on the outer end of the nozzle body O to facilitate adjustment and also to provide a connection. between an inlet aperture S in the nozzle. body 0 and an exterior source of fluid supply (not shown) but which may be steam. by means of a pipe T. The nozzle flange U is adapted. to bear against 'JllQ head G and "form a sight joint and the meeting surfaces of the mange U- un-cl head 6- are preferably niaill chincd so as to be true with each oshcr, and
the parts are preferably constructed and adjusted with the ou'clet i-he nozzle in proper position relative to the throes 3, although the nozzle body 8 may be adjusted longitudinally in different positions if required by inserting; a spacer in the form. of c Washer or pecking material between the meeting surfaces or she flange l] and the head G,
The nozzle body 0 is formed with en in ner tubular extension V, an outer annular flange W, and an annular chamber X loctween the tubular extension V and flange W. 'The tubular extension V projects slightl beyond the end of the flange W and the outer cylindrical wall of the extension V gradually decreases in diameier toward the ouicr end beginning al; a point justabovemil . passage c till into the of the head G, and
"with. an 13] the end of the flange W. An annular ring or cup Z having it reduced diameter screw threaded portion a is adopted to be threaded 'W' which is provided with internal screw threads Z) for this purpose.
The ring Z surrounds the end of the tubui211. extension V and the opening; in the ring Z is of slightly greater diameter than the widest portion Y of the tubular extension V, so that an annular passage or ring is formed between the ring 2 and tubular ex tension V, this ring 0 gradually increasing in volume beginning at the mint Y. longitudinal passage d locate in one side of the nozzle body 0 maintains communication between the chamber X. and the steam inlet T. The longitudinal cylindrical chamber a formed in the tubular extensionV concentrically with the ring passage 0 communicates with a transverse nozzle body leading from the,
the passage communication Wit the inlet E.
A "tubular nozzle 7, is formed integrally- With the hem. G and this nozzle g'is provided rior convergent-divergentpesssge h and extends into the throat B of the h i A, termins ly in alignment inner end it a point approximateportion J of the hody A, this chambersurrounding the nozzle 7 and being adapted to convey Water or other liquid from on i11 let pipe connection it and the nozzle g as shown at p to the, interior of the dilluscr hotly A. The nozzle 9 islo cuted at a point remote from the nozzle body 0 and the position of the nozzle 9 may be adjusted longitudinally and the vol ume of the annular j may be in: creased in; inter-posing n specer between the head (2 nod the portion)? oi Live steam entering: the nozzle through the steam commotion T, passing through the communicating possage into the annular chsmhcr X and mu thence to the rin in the end of the nozzle,,iesdapte d to new into the throat h and. through the diffuser A. in the iormof an envelope'or ring shown at q surrounding the, air of vapor, or hoth, passine from the inlet E to the end of the chamber Within the headGr and into and through the communicating passages f and e, and out of the passage 5 The envelope of steam is as shown at r. itself surrounded, by outer envelo efof the same medium which flows through the, 1 essoges f and a, this outer envelope being composed iluid from theinlet E flowing around the sides of the nozzle Within the inlet head G and downwardly pastthe end of the nozzle between the interim Wall of the head and nozzle 9, end the envelope of s'teum seen at The mixture flowing A -ilowi'ng through the diffuser passage 7 in the v A J I f is open to with the narrowest portion. of the contracted throat B An annular" .chemoer j is formed with-in theenlarged past the end of I cssery to Obtain the body A.
