AUTOMATICALLY-ACTING srarivo" FLAP vnnvn.
Application filed January 17,"1923, Sr1a1 Io. 13,158, and in Germany February 21, 1922.
forms my apparatus may take, reference is to be had to the accompanying drawing in which: v
Fig. 1 is a sectional view of the valve with Fig. '2 is a view similar to Fig. 1 showing a modification.
Fig. 3 is a sectional view of a flap valve having a curved seat combined with a dif-- fusor. I I
Fig. 4 is a plane view of the valve sheet before it is coiled into the double spiral' form.
Referring to Fig. 1 my improved valve is shown "as a' double spiral coiled out of a sheet of steel or bronze or' other elastic material. Preferably both ends of the sheet are left plane, one end C serving as a seat plate to close the port G in the'seat body and;
the other end E bein fastened to the; seat body by a screw S. n Fig. 3 the end E of the coil is clamped between the seat body K andthe plate P b means of screw S. :lo diminish the lift 0 the valve, a diifusor-llke channel D is arranged in theseat body above or beyond the port G of'the seat. Fig. 4. shows the plane sheet of steel or bronze or other elastic material before being coiled.
"accessi 1e it is necessary- The line MM shows where the coiling should begin-in order to produce the double spiral. When valves are mounted as shown in Figs. 1 and 3, where the fastening screws S are outside the spirals, the coils may be rolleil but where the fastening screw is positioned radiall of the coil as in 2, for it to be 'es at-A, Fig. 4. provided to pre-Q of the valve with slotted as shown in dotte If desired,"-jp1 ns s mayvent; the rotatfl i I .evement respect to the sin l e screw If the flap is unusually broa ;1t may r deslrab e to utilize two. or more screwsinstead of the pins.
ve tion, in which the spring part of the valve at. the sheet be ghe practical importance of this .new'
is formed as double spiral, consists in the foli lowing: i
The complicated and costly manner of cuttlng and rolling the substantially U-shaped valve sheet of prior art valves wlthout spindles is obviated for, as shown, the double s iral is rolled from a simple rectangular s eet. It is true that older forms of .flap valves were made from a simple plane sheet, but for mounting such devices it was necessary to provide a spindle, and this is not necessary with the presentJinvention where the sheet in its entire breadth is utilized as a supporting arrangement for the seat plate. Thus'fthe stabilit of the valve is considerbly increased an the thickness of the valve sheet can be smaller.
Taking all distinctive features together, the new flap valve combines the advantages of prior constructions of the type referred to while avoiding their drawbacks.
I declare that what I claim is 1. The combination with fluid flow controlling structure having a converging diverging port, of avalve adapted to close sald port in its region of minimum area, and spring means supporting said valve and permittin oscillatory movement thereof.
2. T e combination with fluid flow controlling structure. having a converging diverging port and a recess opening into said port, of a valve adapted to close said port, and spring means contained in said recess supporting said valve and permitting oscillatory movement thereof.
3." The combination with fluid flow controlling structure having a converging diverging port, and a recess opening into. said port, of means contained in said recess controlling the passage of fluid through said port, said means comprising a double s iral spring formed from a rectangular sheet aving an integral freely oscillatory end portion adapted to close said port, and means for securingil the other end portion of said spring to sai structure.
4. Fluid flow controlling structure comprising a converging-diverging port with a recess opening thereinto, a.seat plate comprising one wall ofsaid port and a double spiral spring said recess having an integral freely-oscillatory end portion closing said port at times and at other times resting on said seat plate;
= 5. In a structure for-.cbntrolling the flow diifusor-like channel beyond said port, a plate forming one wall'of said channel, a flap valve made of a sheet of elastic material comprisin a spring part and a seat part,
5 said sheet eing rolled in such a manner that its spring part forms a double spiral of which the innermost coil begins in, or near the middle of the said sheet, one .end of said sheet being jammed in between the seat body and v 19 said plate, said valve hanging free and movable for its automatic play substantially as described.
6. The combination with fluid flow controlling structure having a port, of a flap valve
