Specification of Letters Patent.
Application filed September 6, 191%. Serial. No. 788,329.
To (ZZZ 10710721615 may concern".
Be it known that l, Gus'mr Vic roe Kem son, a subject of the King of Sweden, and a resident of ihe city of Philmilelphiu, county of Philadelphia, State of Penn vuniu, have invented ccrtuin new and useful Improvements in Dinphru mValves. of which the following is u specification.
This invention relates to diaphragm valves uud more particularly to valv s of this character which are adapted -:o be. used in connection with pressure gages, and has for an object to provide a valve. whereinlhe construction is such that. the pressure may be controlled or regulated and not permitted to rush into the gage under full head.
.lc has been found in practice um dire phregni valves us heretofore conslructe and as used in connection with or like indicating mechanisms. have. some dread vantages. The principal trouble which llllfi developed in the commercial use oi. such valve mechanism i133 been, especiull where. high pressures are used, thut the :lluid surges into the gage with such force us to deflect the indiczu'ging needle to it grew v l jf e then the uc munber of pou upon the This action soon \lSL'r: the. delicure me ounism to our. of order or unbalanced so rluii i will no; (Hl'l v; indicate. the desired iifliii'iniriinir. s cut invention 1 hure eviscd wherein the foregoing defects overcome and cl'n 1mm, and whereby the pressure fluid may be so thron. l and re! iluted as to render its admission to he :1 gradual one, free from slmcl; but. 1 ing in pressure in such a. munner indicating needle moves promprlv and without vibrulion or osclluriuu to We point indicating the pressure dc it has for u furlher an n novel smieture when, the gage may be relieved uiler been when.
ll 'furlher consists of other novel features of invention. as will be. hereinafter fully discussed in the uccmmmnving specification and claims. I
In the drawin s:---Figure '1. a view in front elevation of u gage and vulve body embodying my invention, certain parts of the latter being removed also to provide in iue presMu-c in a reading has gage in side elevation and ulso showing the valve body in t "unsverse section; Fig. '3 represents a plan of a spacing element eniploy'ed in the valve structure; ondVFig. 4 represents a plan of an uportured disk also embodied in the valve structure.
Similar numerals of reference designate correspondingparts in the drawings.
1 designates the valve body provided with the valve seat 2 which, in tlie present instance, is encircled by a groove 3 serving the purpose of a channel for communication between the valve inlet puss-age or conduit l and the outlet channel 5, the latter serv ing as a means to conduct pressure fluid to the fitting 6 of the gage 7 or like device. The groove 3 also serves at certain times to direct the pressure fluid to an exhaust channel 8, which is controlled in the present instance by a needle valve 9 operable by the lhumh screw 10, the. said valve having a longitudinal groove 9 along which the fluid travels in leaving the channel 8.
