INJECTOR.
SPECIFICATION formingpart of Letters Yatent No. 597,212, dated January 1 1, 1898.
Application filed April 7, 1897- gerial No. 631,118. (ModeL) To all whom it may concern:
Be it known that I, Ltpwre AHRBECKER, merchant, a citizen of the Kingdom of Prussia, and a resident of Hanover, in the Kingdom of Prussia and German Empire, have invented certain new and useful Improvements in Injectors, of which the following is a specification.
My invention relates to compound injectors or that class of injectors which employ both a lift-jet and nozzle and a force-jet and nozzle contained in a common casing properly divided into chambers which communicate one with the other and also with suitable valves for controlling the inspiration and injection of the steam and water from the supply-pipes into the boiler 01* water-reservoir.
The object of my invention is to provide an injector which possesses a high degree of suction with the feed-water at a high temperature, which works automatically without special regulating devices, and which possesses in its several parts the greatest simplicity and accessibility.
' The construction of my improved injector is shown in the accompanying drawings, wherein- Figure l is a longitudinal sectional elevation thereof. Fig. 2 is a section on line 0350 of Fig. 1; and Fig. 3, a section on line 3 y of Fig. 1, the nozzles in both Figs. 2 and 3 having been removed.
The body A of the casing contains all of the valves and nozzles properly belonging to the injector and, together with the cap B, which incloses the steanrchaniber O, is adapted .to be connected to the steam-supply by flanged neck I), to the water-supply by flanged neck E, and to the water-discharge by flanged neck F, the steam and water supply pipesbeing provided with stop-cocks in any well-known manner.
The body A of the casing has an inletchamber a, a lift-nozzle chamber a, of crescent-shaped cross-section, forming a cup to receive the lift-nozzle G, a force-jet chamber a a force-nozzle chamber a of circular crosssection, as shown in Fig. 3, an elbow disohargeconduit a a back pressure valve chamber a and a lay-passage a closed at its upper end by a relief-valve H and connecting the force-jet chamber and force-nozzle cham her, a let-oh. cock I being screwed into the easing at the lower end of the by-passage a as shown in Figs. 1 and 3 of the drawings.
The upper end of the by-passage a has a plug K, which gives direct access to the valvecovered branch of said lay-passage, and is also formed with a guide-aperture is, into which is fitted the stem h of relief-valve H, a coiled spring h upon the stem pressing between the valve H and plug K to hold the valve in its seat against the usual working pressure.
The lift-nozzle G has alongitudinal double conical aperture meeting at its contracted ends, above which point a screw-threaded body g, flanged at the upper end 9 is fitted in a seat a in the bottom of the inner end of the inlet-chamber a, the upper end g of the said lift-nozzle projecting above said seat a to receive the jet-nozzle L, which latter is also provided with a screw-threaded body Z, flanged at the upper end 1, and is fitted in a seat a in the top of the inner end of the inlet-chamber 0. in the line of axis of the liftjet nozzle G to hold the said jet nozzle L within the upper end 9 of the nozzle G and at a suitable distance therefrom to provide an annular space around said nozzle, through which the water-supply passes to the liftnozzle.
The force-jet nozzle M has a screw-threaded flanged body an fitted into a seat in the upper wall of the forcejet chamber a and the force-nozzle N has a similar screw-threaded flanged body a fitted into a seat in the lower wall of said chamber, each nozzle being the counterpart, respectively, of the lift-jet nozzle and the lift-nozzle, except that the force nozzle N has relief-apertures 92 passing upwardly and outwardly from the center aperture of the nozzle immediately above the flanged body a to the force-jet chamber a which will allow the excess of steam to be passed up into the chamber a as will here inafter appear.
A back-pressure valve 0 is supported in a seat in the flanged neck F between the chambers a and a and controls the admission of feed-water to the boiler or water-reservoir.
The body A of the casin g when constructed as described may be cast in one piece, the crescent-shaped cross-section of the cup-like the force-jet chamber a the channels lead ing to the by-passage a and from the forcenozzle chamber to the back-pressure-valve chamber being so arranged that the entire system of chambers will lead from one to the other, and the seats for the steam-jet and water nozzles will lie in the same axial lines, thus enabling the parts to be bored or drilled and threaded to fit together in a simple and inexpensive manner.
The casing is preferably made of cast-iron and the nozzles of brass or other non-corrosive soft metal.
The operation of the above-described device is as follows: The steam from the boiler passes into the steam-chamber C and through the j et-nozzle L. The feed-water,passing from the chamber a to the mouth of the lift-nozzle G, is carried forcibly along by the j et of steam through the chamber a and up along and through the side conduits a a into the forcejet chamber a where the water, if it be delivered in sufficient quantity, escapes over the nozzle-partitions and is carried along by the injected steam forced through the force-jet nozzle M and propelled through the force nozzle N into the chamber a in the direction of the discharge-necle The energy of the water thus carried forward overcomes the resistance which presses upon the valve 0, which closes the pipe leading to the boiler and opening said valve, overcoming by its momentum the waterpressure within the boiler. The water, which at the commencement does not possess the necessary speed or energy in consequence of condensation of the steam and other resistances, collects in the chamber M and is let off through the let-ofi cock I at-the lower end of the by-passage a, which cock must be opened when the injector The apertures 71 in the is to be operated.
force-nozzle N serve to lead back the excess steam passing into the force-nozzle N, which would otherwise interfere with the vacuum, to pass into the chamber a so that the same reaches the surrounding channel from above. If too much water reaches the chamber a a surplus pressure is created herein which will open the relief-valve H and lead off the excess water through the by-passage a", from which it may flow off through the let-ofi cock at the bottom thereof, which operation continues until the normal condition is again replaced and the relief-valve H is closed.
I claim as my invention and desire to secure by Letters Patent- 1. An injector comprising a body having a Watersupply chamber extending laterally from one end thereof, and a steam-supply and chamber at the adjacent end thereof, a water-outlet at the opposite end thereof and adjacent nozzle-chamber, a double pair of steam-jet and water nozzles, aback-pressure valve, a by-passage leading from the forcejet to the force-nozzle chambers, and a pressure-valve to control said passage, substantially as described.
2. An injector comprising a body having a steam-chamber, water inlet and discharge chambers, intermediate jet lift and force chambers arranged successively, a set of jet lift and force nozzles, the said force-nozzle having apertures leading from the middle of its conduit to the adjacent jet-chamber, a bypassage leading from the said jet-chamber to the force-nozzle chamber, and a pressurevalve to control said passage, substantially as described.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
LUDWIG AHRBEOKER.
