The annular surface 14 is in perpendicular relation to` the'cylindrical wall 11. VThe lower end of ther yhollow member or can'10 is covered by an upwardly.
bowed closure wall 17 of circular outlinelttedpupon and attached to the lower end of the cylindrical wallnll. g
, Ashell 18.0f the valve apparatus is constituted asa cupV shapey member including a cylindrical A.upper portion 19 having its' external surface engaged against 'the "internal surface 16 of the circular wall v413 and its upper end 20 iny 18,',with a lower, outer circular portion 35 of said hollow body seated against the annular shoulder 21, and an an-v nular passageway 3,6 within the hollow body is contiguous with the stem 29 and the conical valve 28 and the endV of said hollow body adjacent said conical valve, but sealed closed adjacent the end of said hollow body opposite the conical valve by said stem 29 and the annular diaphragm 31. Said annular passageway 36 is bounded at its lower end, or end opposite said annular diaphragm 31, by a downwardly and outwardly extending, inwardly facing, annular valve seat 37 disposed at the inner side `of the conical valve 28, and said conical Valve is in spaced relation to the base 24 of the cup shape member or shell 18. A lateral port 38 in the valve stem 29 above the conical valve 28 is contiguous at its exterior end with the annular passageway 36 and at its interior end with a longitudinal porty 39 in said valve stern, and said longitudinal port is contiguous, at a location above the can, with the interior of an outlet nozzle 40 from said valve stem. As shown, the annular diaphragm 31 includes an upperyportion 41 snugly seated in a downwardly facing annular groove 42 in the valve stem 29 thus to cause thel annular passageway 36 to be closed at its upper end. Said annular diaphragm 31A is constituted as a resilient member Apossessing sutli- 3 cient power normally to retain the conical valve 28 engaged against the annular valve seat 37.
A locking element for retaining the conical valve 28 and the annular valve seat 37 in engaged relation is consti' tuted as a nut 43 having an internal thread 44 engaged with an external thread 45 upon an upper portion of the valve stem 29 above the annular diaphragm 31. The nut 43 will be of size to be readily and easily fitted upon the valve stem 29. The conical valve 28 and the annular valve seat 37 can be retained in engagement by turning the nut 43 down against the annular wall 12 of the can, as it is shown in Fig. l, and the valve stem 29 can be released to be vertically movable in the canby turning said nut to position where in spaced relation to the annular wall 12 of said can.
When it is desired to dispense fluid under pressure from the can, the conical valve 28 will be unseated in response to depression of the valve stem 29against resilient action of the annular diaphragm 31. Upon release of saidvalve stem, said annular diaphragm will immediately react to cause said conical valve to be seated against the annular valve seat. When the conical valve is seated, the exterior end of the lateral port 38 is engaged against and closed by the annular valve seat. When the conical valve 2S and the annular valve seat 37 are in separated relation, flow from the can will be by way of the tube 25, the shell 18, the annular passageway 36 and the ports 38 and 39 to the outlet nozzle 40.
The lower surface of the conical valve 28 fixedly supports a valve element constituted asa body 46 and a guide stem 47 loosely slidable in the opening 26 through' the pipe flange 27 upon the base 24 of the shell 18. The body 46 includes a ilat surface 48 at its lower side, in surrounding relation to the guide stern 47 and parallel relation to said base 24, to be engaged against and removed from an annular valve seat 49 provided by the base 24 in surrounding relation to said opening 26. The construction and arrangement will be such that the flat surface 48 will be removed from the annular valve seat 49, as in Fig. 1 of the drawings, when the conical valve 28 and the annular valve seat 37 are in engagement, and that said at surface 48 can be engaged with said annular valve seat 49 in response to inward or downward manual movement of the valve stem 29, thus to preclude flow of iluid under pressure from the tube 25 into the cup shape member or shell 18. The valve stern 29 can be manually actuated from its position where the conical valve 28 and the annular valve seat 37 are engaged to its position where the at surface 48 and the annular valve seat 49 are engaged in any interval of time which may be predetermined thus to cause tlow of a corresponding amount of lluid under pressure from the hollow member or can 10. Flow will commence with separation of the elements 28, 37 and discontinue with engagement of the elements 48, 49,
and upon release of the valve stem 29, the annular diaphragmy 31 will quickly react, aided by pressure of fluid in the hollow member or can, to return the conical valve 28 to position where engaged against the conical valve seat 37.
The only parts of the valve apparatus with which iluid under pressure being dispensed can come into contact are the tube 25, the shell 18, the body 46 and the guide stem 47 of the valve element, the hollow body 30 and the annular diaphragm 31 of the valve-seat-providing and sealing-oll member, and the valve member constituted as the conical valve 28 and the elongated valve stem 29. As shown, all of the parts of the apparatus to be contacted by fluid under pressure are of non-metallic material, thus to insure that there will be no occurrence of electrolytic action. The hollow body 3), the annular diaphragm 31, the valve body 46 and the guide stem 47 are of molded rubber, and the tube 25, the shell 18 and the member comprising the conical valve 28 and the elongated valve stem 29 are of plastic material.
