VALVE.
Application filed June 28, 1915. Serial No. 85,781.
To all whom. it may concern:-
lie it known that I Ji-isss E. Kerri-in, a citizen of. the United tates, residingin the city of St. Louis and State of Missouri, have invented new and useful Improvements in Valves, of which the following is a specification.
This invention relates to certain new and useful improvements in fluid pressure valves, and has s ecial reference to the production of a nove air valve forum in connection with pneumatic tires, although my invention is not limited to such ap licationa The general object o the invention is to provide a valve which will seat accurately and rapidly, which will respond readily to increase of pressure from either side, and which will be guided in its movements in a manner to insure its travel in right lines with the minimum of friction and wear.
The invention is illustrated in the accompanying drawing, in which Figure 1 is a central vertical sectional view through a tire valve having my improve ments embodied therein, and showing the valve unseatcd; Fig. 2 is a similar view of a portion of said valve showing the valve proper seated; FigfB is a top plan view of the valve proper; *ig. 4 is a view partl in elevation and partly in section of said va ve; and Fig. 5 is a bottom plan view thereof.
Referring now to the drawing, the numeral 1 indicates a valve stem rovided at its lower end with a flange 2 an with a screwthreaded portion 3 provided with a jam nut 4 for securing the valve to the tire, these parts being of the usual or any preferred construction.
Extending centrally through the valve stem is a bore 5 which terminates at its upper end in a valve chamber 6, conoidal in,
shape, the smaller end of the chamber terminating at and coinciding with the upper edge of the bore The upper portion of the chamber 6 presents straight side portions 7 which extend parallel with the axis of the stem 1. Mounted in the chamber 6 is a valve 8 which is also conoidal in shape. The valve 8 is flat on its upper end to provide a seat 9, and in its lower end is provided with a circular recess 10. The numerals 11 indicate a series of moves which are provided on the outer si e of the valve 8 and extend from top to bottom thereof; at the bottom communicating with the recess 10, and
at the top providing an opening through which air may pass. Four of these grooves are shown, but a greater or less number may be employed.
The upper ortion of the valve 8 is substantially of tlie same diameter as the upper or straight portion 7 of the valve chamber 6, so that in its movement it will be guided by such straight portion of the valve chamber. The remaining portion of the valve 8 is of the same configuration as the lower portion of the chamber 6, and of the same dimension so that in the unseating movement it will not only be guided in a right line by the straight portion 7 of the valve chamber, but will automatically settle itself with the recess 10 directly over the top of the bore 5, as shown b Fig. 1, due to the uniform curvature of the wall of the chamber 6 and of the outside of the valve 8. The valve 8 is, of course, of less height than the chamber 6 so that it may have a limited movement in seating and unseating.
The upper ortion of the stem 1 is intoriorly screw-t ireaded and screwed into said upper end is a head'l2 having a central bore 13, the bottom of said head surrounding the bore 13 being flat and forming a valve seat for the valve 8. The head 12 has a screwthreaded extension 14 which is adapted to receive a cap 15 having a projection 16 thereon, as usual, for unseating the valve 8 when desired.
When a pump is attached to the projection 14 and operated the valve 8 will be unseated by the pressure of air from the pump and the air will pass through the bore 13 and through the grooves 11 into the bore 5, and thence into the tire. As soon as the pressure of air on the valve ceases the back pressure of the air from the tire is first exerted on the top of the recess 10 causing the valve to at once be forced outward and seated. \Vhile it is true that a certain portion of the air will tend to pass through the grooves 11 and escape through the bore 13, the tapering shape of the valve 8 offers a sullicient resistance to the free passage of this air through the grooves 11 to cause it also to supplement the action of the air on the recess 10 in raising the valve. As the. valve has only a slight movement in either direction, say about a sixteenth of an inch. it will, in consequence of the action of the air thereon as above described. be seated by Patented June 6, 1916.
the back pressure of the air with the utmost rapidity as soon as pressure is released from its seat, and such back pressure of air will cause the valve to be firmly held to its seat until again displaced in the pumping operation.
I claim:
1. A device of the class described, com: prising a valve casing provided with a conoidal-shaped valve chamber, with bones leading into said chamber from opposite ends thereof, and with a flat valve seat surrounding the bore at the larger end thereof, and a conoidal-shaped valve mounted in said chamber and provided with grooves on its outside extending from top to bottom thereof, said valve being of substantially the same cross dimensions as said valve chamber, but relatively shorter, and the larger end of the valve affording a flat seat corresponding to the seat of said valve chamber.
2. A device of the class described, comprising a valve casing provided with a conoidal-shaped valve chamber, with bores leading into said chamber axially from opposite ends thereof, and with a valve seat at its larger end and surrounding one of said bores, and a conoidal-shaped va ve mounted Copies of this patent may be obtained in in said valve chamber and provided at its lar er end with a seat, in its smaller end wit a recess alining with the bore at the adjacent end of the chamber, and on its outer side with grooves extending from top to bottom thereof and communicating with said recess.
3. A device of the class described, comprising a valve casing provided with a. conoidal-shaped valve chamber, the portion thereof of largest diameter having substan tially straight sides, said casing having bores leading axially into opposite ends of said chamber, the portion of said chamber at the lar er end thereof and surrounding one of sai conoidal-shaped valve mounted in, and of substantially the same shape and diameter as, said chamber, but relatively shorter, said valve being provided at its larger end with a seat, at its smaller end with a recess alinin with the other of said bores, and in its si e with grooves communicating with said recess and extending to the larger end of the valve.
In testimony whereof, I have hereunto set my hand.
