VALVE Original No. 821,507, dated Kay 22, 1006,

To all whom it may concern:

Be it known that I, WILLIAM H. KLINE, residin at Dunbar, in the count of Fayette and tate of Pennsylvania, (an whose ostofiice address is Dunbar, Pennsylvania) ave invented anew and useful Valve, of which the followin is a full, clear, and exact description,'re erence being had to the accom- 1panying drawings, forming part of this specication. I

My invention relates to valves, and especially to that class of valves ada ted for controlling the flow of fluid un er ressure, wherein the valve is itself controlle( by fluid pressure.

The object of my invention is to provide a valve especially for use in connection with blowing engines or -air-compressors using the well known form of gridiron ort-closure to control the flow of compresse fluid from the compressor to the storage tank, wherein the ridironport-closure is operated b a cyliner and piston. Mgr improved va ve is deflow of acompressed fluid from the com ressor to the valve actuating cylinder an piston so that the ort closure will be open to admit the flow of" uid from the compressor to the tank only when the tension'of the fluid in the compressor becomes equal to or greater than the tension of the stored fluid in the tank. It is well known that in the type of compressor mainly used the ort closure is o erated either mechanica ly and positive through the medium of an eccentric or is opened by the tension of the compressed fluid in the compressor and closed positivel through the medium of the eccentric. 'It is also well known that in compressors where the port-closure is opened by the action of the compressed fluid, the port closure piston is operated as soon as the tension of the fluid becomes sufficient to pass the usual check valve located in the pipe which conducts the fluid from the compressor to the port closure cylinder. such fluid pressure operated port-closure'it I is well known that the port closure is opened before the pressure becomes as great asthe pressure in thestorage tank. .It is desirable that'the ort closure remain-closed until the tension 0 the fluid in the compressor equals the tension of the fluid in the tank, so that In compressors supplied with Specification of Reisaued Letters Patent. leis sued Sept. 22, 1908.

the admitted fluid shall be of a tension similar to that alread stored. My improved valve is held in a c osed state by the tension of the fluid in the tank until the fluid pressure in the compressor becomes equal thereto when it is automatically opened to permit the introduction of fluid to the port closure cylinder and against the piston operating t e ort-closure.

ith these and other objects in view the present invention consists in the combina tion and arrangement of parts, as will be hereinafter. more fully described, shown in the. accompanying drawings, and articularly pointed out in the appended c aims, it

.being understood that changes in the form,

'closures mounted within t e pump body and my improved valve mounted thereon to control the flow of fluid from the pump to the cylinder. Fig. 2 is a side elevation partly in section, showing a compressor engine with the gridiron port-closure for controlling the flow of fluid from the pump to a storage tank and the manner of mounting and operatin my improved valve. Fig. 3 is a detaile lanview; Fig. 4, a detailed section view; ig. 5, a detailed .side elevation of m improved valve, together with a vertica section of the port-closure-operating cylinder and piston. Fig. 6 is adetailed side elevation showing the connection with the throttank 4 is rovided in which is stored the comv pressed uid supplied thereto from the pump 2 through pipes 5.

-- which are closed positively through the medium of the lever 9, connecting rod 10, and eccentric 11. A pipe 12, connectingwith the pump, conducts the compressed fluid to the cylinder 8. Within this pipe 12 I locate my improved valve, consisting of a valve casing A valve 15 1s mounted within the valve casing 13,

adapted to freely reciprocate and to engage the seat 14. Above the reci rocating valve 15, the, casing is rovided wit h achamber 16 and a pipe 17, eading'into such chamber. The pipe 17 is connected with a line pipe 18, connected with and adapted to conduct fluid from the storage tank 4. Above the chamber 16 is rigidly secured to the casing an angular arm 19, upon which is ivotally mounted a' eating valve 15.

A lever 23 is provided with a roller 24 upon one endthereof and pivoted to any-conven- The roller'is so dispose as to contact with and be I operated by a disk 26, rigidly secured to and rotatin with the throttle valve operating hand w eel 27. The end of the lever 23 opposite the roller 24 is connected with the arm 20, so that the closing of the throttle valve will close and hold the valve 15 in such closed position. A by-pass 28 is provided for the passa e of the fluid around the valve and is rovi ed with an ordinary check valve 29, ocated therein.

The operation of my improved valve is as follows; The pipe 12 pierces the wall-of the pump and leads to the cylinder 8. The pi e 18 leads from the storage tank 4 and into t e chamber 16 above the reciprocating valve 15.

piston therein to slidably unseat gridiron port-closure 6 to permit the passage of the compressed-fluid through the port from the It will therefore be seen that no fluid is admitted to the pipe 5 and tank 4 of a less tension than the fluid already contained in the tank. Upon the completion of the stroke of, the piston 3 the port-closure 6 is positively closed fhrough'the'medium of the eccentric 11, rod 10, and lever 9 in the usual manner. With the return of the piston within cylinder 8 to the position to close the port closure 6 the compressed fluid used to operate said piston is usually permitted to escape. In my improved valve the mechanical and positive return of the port-closure 6 to seatforces the fluid within said cylinder through the bypass 28 and check valve 29,

While I have shown and described my valve in connection with a blowing engine or com ress'or, for which use it is primarily inten ed, it is evident that it could as Well be used for any other purpose where. it is desired to control the flow of a fluid and maintain such flow at a tension equal to the tension of'a fluid from a diflerent source. It is also obvious that minor changes in the form and construction of the valve may be made by one skilled in the art without departing from the spirit of my invention.
