VALVE.

Application filed November 6, 1920. Serial No. 4=22,211.

To all whom it may concern.

Be it known that I, OSCAR R. VIKANDELR,

a citizen of the United States, residing at Glen Ridge, county of Essex, and State of NewJersey, have invented certain new and useful Improvements in Valves, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in valves for use in air compressors and similar machinery, which is simple and effective in construction, which is sensitive in operation, which permits the initial opening movement to take place quickly, so that the valve opens rapidly, and which effectually cushions the valve at the end of its opening movement, thereby preventing shock and securing the desired action and long life at high speeds.

With these and other objects not specifically referred to in view, the invention consists in certain constructions, parts, improvements and combinations as will be herein after fully described and then specifically pointed out.

. Referring to the drawings which illustrate concrete embodiments of the invention Figure 1 is a side elevation, partly in section. of a construction embodying the invention.

Figure 2 is a sectional line 2-2 of Fig. 1.

Figure 3 is a side elevation of a modified iprm' of construction embodying the invenion.

Figure 4 is a side elevation of another modified form of construction.

Figure 5 is a vertical section ofthe construction shown in Fig. 4.

- Figures 6 and 7 are sectional lan views of the construction shown in ig. 4, the planes of section being indicated by the lines 5 6-6 and 7-7 of Fig. 4, respectively.

Referring to the drawings, and particularly to Fig. 1, l indicates the valves seat which, as shown. has annularly disposed ports therein, and 2 indicates an annular valve 50 cooperating with said ports. An abutment consisting of plate '3 is provided, this plate being secured by a nut 4. or in any other suitable manner. to a central guide 5 which lies within the annulus of the vlave. Con- 5 struction embodying the invention will inplan view on the clude a pair of plates arranged to form a bow spring that is, a curved plate with a second plate extending across the concavethat both plates have a central opening and are disposed about the central guide 5. In the construction shown in Fig. 3, the corrugated plate 6 is the lower plate and the uncorrugated curved plate 7 bears againstthe abutment. Both these constructions are sensitive and allow an easy and rapid start ing movement of the valve. In both constructions, the resisting effect of the spring increases rapidly as the valve opens, so that, at the end of the stroke, the springs are strongly compressed and the valve is effectively cushioned.

In the construction shown in Figs. 4, 5 and 6, a spring which is supplemental to the how spring is employed, this construction being particularly adapted for large valves and valves which comprise a pluralityot annular plates arranged one within the other. In this construction shown in these figures, the valve seat is provided with a plurality of ports 8, 9, and the valve consists of a plurality of annular plates 10, 11. The inner plate 11 is disposed around the central guide 5 and is guided in its movement thereby. Additional guides, as 12, may be employed to guide the outer plate in its movement. The control springs include the plates 6 and 7 forming the bow spring before described, but a supplemental spring construction is employed in connection therewith. While the construction of this supplemental spring may be varied, as shown it comprises curved or bowed

plates

13, 14 between which is arranged an intermediate plate 15. In the construction shown, the plates are curved upwardly and have openings through which the annular guide passes. The plates 6, 7 are also provided with openings through which the guides 12 pass, these openings being large enough to permit the necessary movements of the spring plates as the valve opens and closes.

The invention may be embodied in constructions other than those illustrated. The invention is not, therefore, to be restricted to the particular constructions shown.

' What is claimed is: v V

1. The combination with an annular plate valve and an abutment, of a pair of spring plates for controlling the movement of the valve interposed between the valve and the abutment, said plates being arranged to form a single bow spring, and one of said plates being corrugated or waved.

2. The combination with an annular plate valve and-an. abutment, of a pair of spring plates for controlling the movement of the valve interposed between the valve and the,

abutment, said plates being arranged ,to form a single .bow spring, and one of said plates being formed with parallel corrugations. 1

3. The combination with an annular plate valve and an abutment, of a pair of spring plates for controlling the movement of the valve interposed between the valve and the abutment, said plates being arranged to form a single bow spring, the plate which is next the abutment being formed with parallel corrugations. I

4. The combination with a plate valve comprising a plurality of annular plates, of

, an abutment, a central guide lying within the annulus of the inner plate, a pair of spring plates interposed between the valve and the abutment, said plates being arranged to form a bow spring, and a supplemental spring arranged within the bow spring.

5. The combination with a platev valve comprising a plurality of annular plates, of

an abutment, a central guide lying within the annulus of the inner plate, a pair of spring'plates interposed between the valve and the abutment, said plates being arranged to form a bow spring, and a supplemental spring ineluding a plurality of curved. plates arranged within the bow spring.

6. The combination with a valve, of an abutment, a pair of spring plates interposed plates being arranged to form a bow spring.

and the plate lying next the abutment being corrugated or waved, and a supplemental spring arranged within the bow spring.

9. The combination with a plate valve, said valve comprising a plurality of annular plates, of an'abutment, a central guide lying within the annulus of the inner plate, a air of spring plates arranged to form a 0w spring interposed between the valve and the abutment, one of said plates being corrugated or waved, and a supplemental spring including a plurality of curved 'platesarranged within the bow spring.

10. The combination with a plate valve comprising a plurality of annular plates, of an abutment, a central guide'lying within the annulus of the inner plate, guides for the outer plate, a pair of spring plates in-'.

terposed between the valve and the abutment, said plates being arranged to form a bow spring, and one of said plates being waved or corrugated, and a supplemental spring arranged within the bow spring, said supplemental spring comprising a plurality of curved spring plates and an intermediate plate.

In testimony whereof, I have hereunto set my hand.
