This invention relates to valves and more particularly gas compressors to valves adapted to be used in and operated by pressure of the fluid being compressed.
It is an objec t of the invention to mount the movable parts ofthe valve 'in such a manner that relatlvely little wear takes place and to ellmlnate bending in weak portions of the valve.
Another object of the in Other objects and vention will be advantages ofthe in- 1n part obvlous and 1n part pointed out hereinafter.

Figure 6 isa along the direct-ion of the vertical sectional view taken line 6- 6 of Fig. 5, looking in the Referring to the drawings and more particularly to the embodiment shown in Figs.
1 and 2, the valve comprises a provided with a valve seat A plurality of ports B, in this instance extending radially with respect to the center of the valve seat A. In this instance the valve A is circular in outline On the periphseat ery of the seat A there is provided a flange C'ada ted to seat in the valve opening Ig The flow of shown of a sui fluid through tl controlled by a having a flat lower face.
(not table cylinder. 1e' ports B is adapted to be plurality of valve fingers D The valve fingers D are independent of each other being formed of separate thin pieces of flexible material adapte pressure of the d to bend slightlyfrom the iuid on their lower faces to uncover the ports B. A valve stop plate E mounted on the valve seat A and rigidly attached thereto by means of a bolt F which is provided with curved lower faces G adj acent the valve fingers D, the curvature being approxlmately the natural curvature of the fingers D when raised from the valve seat A by pressure of the fluid beneath.
. The valve fingers D are each provided with a bent-up inner end H which is adapted to be engaged by a coil spring J inserted in an aperture K in the stop plate E at the face adjacent the valve seat A. VThe coil spring J may have a polygonal outline as shown in Preferably the valve fingers D are tapered, belng Wider at their outer ends than at their inner ends to provide space for the fluid passing the valve fingers D from the ports B. Preferablv the stop plate E is formed with fingers L of the same general outline as the valve fingers D and extending radially from the center of the stop plate E over the valve fingers D. The space between the valve stop fingers L allows ample space for the Huid to pass the stop plate E.
'Each of the valve stop ngers L is provided with an aperture O preferably circular to receive coil springs P normally tending to press the valve fingers valve seat A. The springs P are adapted to cushion the valve fingers D as they rise and strike against the stop plate fingers L. Furthermore, `the curvature of the lower face G of the stop plate fingers L causes the flexure of the valve fingers D tending t-o start the fingers D back toward the valve seat A upon the release of pressure beneath.
It the ports B are relatively wide the valve fingers D may be prevented fromcollapsing by means of an inwardly projecting tongue Q with which the fingers D are adapted to contact while lying flat ou the seat A. ln order to prevent sidewise motion of the valve fingers D there are provided pins R inserted in the valve seat A adjacent the outer ends of the fingers D.
In the embodiment shown in Figs.`3 and 4, a valve seat b is provided with a stepped upper face including au inner plane surface c and au outer lower surface or step (l. Each of the steps c and (l is provided with a plurality of ports e and f respectively controlled by a plurality of valve fingers g an D against the j vlz. respectively held in place in substantially the same manner as the valve fingers D. To this end a stop plate y' is prqvided with curved faces c and o overlying the "alve fingers g and h respectively and adapted to imit the raising of said valve fingers. The
inner set of valve fingers g is provided with bent-up inner ends p engaged by a polygonal spring q inserted into an aperture 1' in this stop plate j; and the outer set of valve fingers It is held in position by means of a coil .spring s inserted in a cut away portion t be controlled by substantially rectangular valve fingers 4 having their inner ends 5 bent-up to be engaged by coil springs 6. The raising' of the valve fingers 4 is hmited by the lingers 7 of a back stop 8 mounted on the valve seat 2 and rigidly attached thereto by means of a bolt 9. The under faces l() of the stop plate fingers 7 are preferably curved to fiex the valve fingers 4 upon rising.
'Thus by the above construction are accomplished among others, the objects hereinbefore referred to.
1. A com having a purality of ports, a stop plate mounted on said valve seat having a plurality of apertures directed toward said ports and curved on its lower face, a plurality of valve fingers interposed between said valve seat and portions of said stop plate to control the flow of fluid through said ports, a spring around a portion of said stop plate to engage said fingers at one end of said fingers, and springs in said apertures normally tending to press said fingers against said stop plate.
2. A compressor valve comprising a valve' seat having a stepped surface having a plurality of ports in said steps, a stop plate mounted on said valve seat having curved faces adjacent the ports in said steps, a valve finger for each of said ports adapted to control the flow of fluid therethrough and having an up-turned end, springs between said stop plate and said valve fingers adapted to engage said lingers at their up-turned ends, said stop plate being provided with apertures directed toward said ports and said valve fingers, and springs in said apertures normally tending' to press said fingers against said stop plate.
,In testimony whereof I have signed this specification.
