I CHARLES VI'IEK, OF MAYWOOD, ILLINOIS.

VALVE.

Application filed March 17, 1922. Serial No. 544,405.

T 0 all whom it may concern: a

Be it known that I, CHARLES VITEK, a citizen of the Republic of Czechoslovakia, residing at Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Valves, of which the following is a specification.

This invention relates to valves and has particular reference to that type of valve which is adaptable for use as a compression pet cock, so termed, or as an exhaust valve. It is also adaptable for use in connection with any fluid such as air, gas, or water and may be readily employed as a priming cup valve for internal combustion engines.

his the object of this invention to provide a valve of the aforesaid character and one which will be not only simple in construction but positive in operation.

With these and other objects in view my invention consists in the novel construction, combination and relative position of the parts and members hereinafter described and shown in the accompanying drawings, and particularly pointed out in the appended claim.

Referring to the drawing in which like reference characters indicate like or corresponding parts:

Fig. 1 is an elevation of a valve in open position embodying my invention, and Fig. 2 is a vertical cross section of same taken on line 22 of Fig. 3.

Fig. 3 is a plan view of the valve in open position.

Referring to the illustrations, my irnproved valve here shown comprises a stem 10 which is provided with threads 11 for connection purposes with a pipe, tank, engine cylinder or any other apparatus where found useful. The upper portion of the stem 10 is formed with a slightly enlarged head 12. An interior passage 13 extends through the head 12 and stem 10 and is disposed at an angle to the vertical or central axis AB of the valve in a way that its lower end is approximately on the center of the axis AB and its upper end eccentric thereof, see Fig. 2.

The head 12 is provided with threads 14 which are preferably cut on a relatively small pitch to insure a fluid tight contact for the cup cap 15 which consists of an annular cup 15 and a lower interiorly threaded portion 15 separated from the upper cup portion by the horizontal wall 15 which is provided with an opening 16 located eccentrically to the vertical axis A-B and on a radius therefrom to align or register with the interior passage 13 when the valve is in open position as shown in Figs. 2 and 3. It is obvious that when the valve is in open position as shown in Fig. 2, there will be a slight space 1'7 between the ground underside or face of the wall 15 and the top face of the raised wall 12*, bothof which surfaces are ground or faced for contact when the cap 15 is turned to the closed position.

It is also obvious that when the valve cap contact with the small annular raised in 5 tegral portion 12 so that the passage 13 is closed within the cap 15.

If desired, the head 12 can be arranged with a pin stop 18 projecting under the cap 15 and an integral lug 15 can be cast to the under edge of the cap 15 to provide a positive stop for alignment of the .opeuin l6 and passage 13 when the lug 15 an stop 18 contact as in Figs. 1 and 3.

Due to the raised annular integral surfaced wall 12*, a space 17 is provided between the under face of the wall 15 and the top of the head 12, even when the cap is in closed position in tight frictional en g'agement with the surfaced wall 12 raised wall 12 eliminates the surfacing of the entire top of the head 12 and provides a space 17 for small dust or the like, which might otherwise affect the air tight closing of the valve.

I claim:

A valve comprising a pair of screw-connected members, one of said members having a lateral wall and an opening eccentric to its axis of rotation, the other member This Y f if 1,511,692

her surrounding said upper end; of said passage arranged for frictionaleontact with CHARLES VITEK.
