per se; and" Patented Nov. 24, 1931 n. or v crncaeo; inmnors 'VALVE ronto Application filed. member 2 "This invention relates to a valve, either suction or discharge,= which is particularly adaptedfor compressors, blowing engines, and the H like.- It comprises a seat member, a "stop 5 plate" andan intermediate r eciprocable valve plateitdgthenwith spring means'by which the'valve isurged toward its seat. The present improvements are concerned primarily with the spring means which'permit of an increased volume of air passing through and around the valve} plate due to larger area of the ports therein, and of a 'higher'lift' of the valve plate fromits seat. a A suggestiveembodiment of the invention m is set forth in the accompanyingdrawings wherein 1 r Figure 1; is an axial valve assembly A V p 1 I Fig. 2 is a top plan' View of the-valve plate section through the ail in section on line 8-3 The present valve assemblywhich is adapted' for attachment directly to a compressor wall or to a cage which is carried thereby, includes a seat member A with which-is associated a stop plate B" detach-ablyconnected to the seat as through the medium of-a boltC the head 10 of'whichiimayfrest. against the outer side oflthestop platefas shown. In-
terpo'sed' between these parts i's a distance piece D] which may'also-serve as a centering means for a reciprocable valve plateE in the form of a disk against which a constant pressure is exerted by spring means 21", the disk shaped ports or openings having an' aggrej gate area which, by preference; is the maximumjobtainable with "due regard for safety and strength. The-memberA isformed with a seatcomprising ribs 15 and' 16 extending thereof.
which I have suggested as a convenient means forattaching thexstop plate to the seat member'permitstheseparts to be readily, disconnected whenever desired. The distance piece D which is in the form of a ring or bushing is-disposed with one end against the hub of the seat memberand with its other e'nd against a hub: 17 that is .formedcentrally of the stop plate- .This bushing extends freely through thecenter portion of the valve plate, 1
butioutof contact therewith, so asto offer no frictional'r'es The stop plate which is ofa diameter about the same as the seat memberisprovided with inner and outerdepending annular walls 19 istance to the reciprocations and'20'respectively.1 The loweredgesof these walls terminate. at a predetermineddistance from theseat member,andconstitute an abutment against which the valve. plate strikes when lifted off its seat to the, maximum :distance. lnzsuchhlifted position of the. valjvejplate, air entering through theports between the spokes of the seat membermay pass on around the edges of the valve plate for delivery .to a desired point. The valve plate is normally held .upon; its seat byv a plurality of like -spring: means formed integrally with itself, and tempered to a desired degree oftensioni -l As shown bestin Fig. 2,. the v central portion of-thevalve plateis' out, Out to provide an inner circularfedge adjacent whichjare arms each of which comprise three mainportions which-II will termthe fulcrumsection 20, 'the radial section 21, and the free end sectionr'22. :Each fulcrum arm section which terminates "inva head 23: integral with the valve plate atadistance of from, the
remainingh'eads, is extended around 'inthe same direction in general conformity" with thercircular inner-edge ofthe valve plate.
For the major portion of its length,.as definedrby 'twosho'ulders 2 4,the fulcrum section is ofreduced thickness, thepurpose bei ing to increase the flexibility of the springf at i this! point. Each spring arm which continues through the radial section and thence p V 7 through its free end section .in agradual rise,
upwardly from thehub and'rimn The boltC is in effect fdoubled uponlfitselfso as toppew an turned lip 25 pointed to enter a Cone- 1 socket provided for its reception in the under three contact lips 25 each situated 120 from .9 the others, and each adapted when seated side of the stop plate. 7 I it,
The spring means just described-is "ti1pl1'-'- cated in the construction shown; that is, three: v.
spring arms each alike are provided for the 1 Valve plate, the arms presenting portions close to each other but not overlapping, and'each occupying a-portion ofthe space centrally of the valveplate within an arc ofless than 120, The effect of this arrangement is to provide against the stop; member, to maintain the valve plate centrallyupon its seat. The space; between the freeends' of the arms is ample for the hub 17 of the stopr plate to pass therethr'ough,-so that no friction will occur during reciprocations of the valve plate; The arrangement of the springarms i wall 19'of-the's'top plate. This wall engages furthermore is one which provides forthe maximum areaof openings in the center region otthe plate. It will be noted that the Valve plate springs are confined within an area thatis inside of the-inner. depending with {thevalve plate'just to the outside of thes r'ings (see Fig: 1),
the valve is ofi its-seat, is directed away from the springs past the eute euges of the stop plate.-
The present valve construction is advent tageeas in that the springs being formed in; tegral with the valve plate require noseparate mounting or assembly. Theyare em tirely frictionless, and because-of their. ar-
rangement and disposition are endowed with unusual length, thereby making possible a higher lift of the valve plate with a consef quent increase in capacity.
