WATER-COO LED'VALV'E.
SPECIFICATION forming part of Letters Patent No. 698,474, dated .April 29, 1902. Application filed October 25,1901. Serial No. 79,946. (No model.)
T0 aZZ whom, it may concern.-
Be it known that I, HERMANN EDGAR Enns, a subject of the King of Great Britain, residing at Nuremberg, Germany, have invented certain new and useful Improvements in Water-Cooled Valves, of which the following is a specification.
The present invention consists of an iinproved Water-cooled valve and comprises the details of construction hereinafter set forth, and particularly pointed out in the claims.
In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.
Figure lis a vertical section through a valve provided with the cooling device, and Fig. 2 is a horizontal section showing the upper water-channel.
The invention may be applied to any class of valve and is particularly advantageous in connection with the outlet-valves of hydrocarbon-engines.
To the body a of the valve the stem b is screwed in the known manner by means of its flange c, the parts being rendered tight by means `of a packing-ring cl. Between the body a and the inner face of the flange c two sets of channels h and t' are arranged, through which the cooling fluid first passes from the center of the valve to the rim along the upper channel and then down the opening 7c to the outer end of the lower channel fi, back through the latter to the center of the valve, and out through the hollow stem b, the inner diameter of which is larger than a tube Z, extending through the interior n of the said stemandY through which the cooling iiuid is fed to the center of the upper channel h. The two sets of channels h and c' may be formed in any desired manner; but it has been found adchannel of a spiral shape, as will be seen from Fig. 2, leading in a set-of coils from the center to therim and being cut in the interior face of the body a of the valve. An intermediate plate e, having a smooth upper face and a channel 75 in-its lower face, is then closed against the ends of the ribs f of the upper out at the stem.
channel, and the flange c closes against the ribs g of the channel of the intermediate plate e, the outer ends of the two channels being in communication one with the other through the vertical port 7s and the center of the lower spiral channel v) being in communication with the interior of the hollow stem outside the feed-pipe Z.
As will be readily understood from the foregoing speciication, the cooling fluid passes through the pipe Z to the center of the upper spiral channel h, along the same, down the port 7.2, and back along the lower spiral t and In its passage the cooling fluid circulates thoroughly over both faces of the valve and will eifectually cool the same.
I claim as my invention 1. In a valve, the combination of a hollow body having a spiral groove therein, an intermediate plate closing said groove, said plate having a similar spiral groove in its base, means for closingsaid similar groove, a port for establishing communication between the `two spiral grooves, and means for causing a flow of cooling liquid through the said spiral grooves, substantially as described.
' t 2. In avalve the combination of a hollow body having a spiral groove therein extending from the center to the rim in a plane parallel to the valve-face, an4 intermediate plate having a smooth face to close the said spiral groovev and having asimilar spiral groove in the opposite face, a hollow valve-stem having a smooth face to close the lower spiral groove and adapted to screw into the hollow valvebody, the interior of the hollow stem being in communication with the center of the lower channel, a Huid-feed pipe within the said hollow stem in communication with the center of the upper spiral channeland a port to establish communication between the outer ends of the said upper and lower channels substantiallyas described and for the purpose specified.
In witness whereof I have hereunto set my hand in presence of two witnesses.
