One obect of my invention is to provide a novel type of exhaust valve wherein the exhaust ports of the housings are always maintained in alignment without interfering 25.* with the proper movement ofthe inner housin gAnother obect of my invention is toprovide a novel type of housing member which is simple, inexpensive to manufacture, and which lends itself readily` to cooperation with an associated housing to prevent undesirable relative movement therebetween.
- For a more comprehensive understanding of my invention reference may now be had to the accompanying drawings of which:
Fig. 1 is a cross-sectional view of a portion of a compressor cylinder provided with andexhaust valve embodying my invention; an
Fig. 2 is a side elevational view of an outer housing member constructed in -accordance Y with my invention; and
Fig. 3 is a bottom plan view of the housing illustrated in Fig. 2; land Fi 4 is a plan view of an inner housing mem er constructed in accordance withmy invention; and Y Fi 5 is a side elevational view of the housings owninFig.4;and v relation; and
1927. Serial No. 199,442.
Fig. 6 is abottom plan view of the housingillustratcd in Figs. 4 and 5; and
ig. 7 is a perspective view of the inner and outer housings assembled in cooperative 55 Fig. 8 is a bottom plan view of the housings assembled as shown in Fig. 7.
Referring first to Fig. 1, have shown a compressor cylinder 10 provided with a piston 11 and a cylinder head 12. The cylinder head 12 is provided with an exhaust ort 13, the passage of compressed fluid t rough which is regulated b a valve mechanism 14, constructed in accor ance with my invention. The valve mechanism 14 is enclosed within an outlet chamber 15 in a cylinder top 16. A fluid conduit 17 secured to the cylinder top 16 is normally in open communication wit the chamber 15 and serves to connect it to a condensing coil (not shown) of the refriger-l ating system.
The cylinder head 12 is provided with an annular raised ortion 18 immediately surrounding the ex aust port 13, which serves as a valve seat for a suitable valve closing member 19, and with an annular groove 20 immediately surrounding the raised annular valve seat 18.
The valve closing member 19 is a thinilex-` ible metallicdisc and is resiliently held in position upon the seat 18 by means of a' helical compression spring 21. A housing member 22 is provided with a centrall depressed portion 23, the face of which is at and serves as. a stop member for the valve'closing member 19. The depressed portion 23 is provided with a small opening 23a therein, which serves to prevent the formation of a vacuum between the valve closing member 19 and the face of the member 23, when they are in engagement. The housing 22 iswalso provided with a plurality of spaced integral downwardly lprojecting supporting legs 24, the
ends of which are adapted to rest in the groove 2O in the cylinder head 12. Intermediate the 95 legs 24, the housing 22 has a plurality of outwardly ,extendin integral projections 25, for -a purpose to hereinafter explained.
.. The housing22 is .resiliently held in its lowermost position, the ends of the legs L00 24 in the bottom of the groove 20, by means of a helical compression spring 26, the other end ot' which is compressed and held in position by means of an outer housing` 27. The holising 27 is provided with a ralsed central portion 28 which engages one end of the spring 2G and which is provided with a central out-A bolts 33.
lAs best shown in Figs. 7 and 8., the spaces between the spaced legs 24 of the housing 22 serve as exhaust ports from the housing 22 and the spaces between-the spaced vlegs 31 of the housing 27 serve as exhaust ports therefrom. The outwardly extending projections 25 of the housing 22 extend between the legs 31 of the housing 27, thus permitting the housing 22 to move toward and away from the stop portion 30 of the housing 27 but prevent relative rotative movement of the two housings.
From the foregoing description it will be apparent that the housing 22 mayn move freely against the action Iofthe spring 28 toward and away from the valve seat 18 but that the lugs or projections 25 ofthe housing 22 moving between the legs 31 of the member 27 will prevent any rotative movement of the housing- 22, thus retaining the exhaust ports of the housings 22 and 27 always in alignment and always open. f
Athough I have illustrated but a single form of my invention, and have described in detail but a single application thereof, it will be apparent to those skilled in the art that it is not so limited, but that various modifications and changes may be effected therein-` wlthout departing from the s irit of my invention or from the scope o the appended claims. I claim as my invention 1. Ina discharge valve, a valve seat, an independently reciprocable valve closing member adapted to engage said seat, a spring member adapted to engage said valve closin member, a reciprocable housing for sai spring member, and means forlpreventing rotary movement of said housing.
