Application filed my 19,
This inventionrelates in general to provements in the art of circulating fluids, and relates more specifically to an improved circulating system for the cooling fluids 1n the jackets of prime movers such as internal 'An object, of the invention is to provide an improved circulating system which is simple, efiicient and automatic in operation.

circulation of the cooling medium in the jackets of prime movers such as internal combustion engines. A further object of the invention is to provide an improved method of equalizing the temperatures of the cooling water or other medium in acketsor the like, by causing all portions of the cooling medium to constantly travel along a predetermined path, and by supplying and delivering regulable quantities oi the medium to and from the jacket. These and other objects and advantages of the 1nvention will appear from the following description. A clear conception of an embodiment or y the invention and of the operation of systems constructed in accordance therewith, may be had by referring to the drawing accompanying and forming a part oi this specification in which like reference characters designate the similar parts.
The single figure of the drawing illustrates a transversevertical section through V a gas engine cylinder embodying the 1m-- provement. c I
The gas engine cylinder to wh ch the 1nvention h been specifically applied by way of illustration, comprises an inner annular wall 4 having therein a liner 3 which surrounds the combustion chamber 2, an outer wall 5 surrounding and spaced from the 111- ner wall 4 by means of radial ribs 6 to form an annular jacket space 7, and a plurality of inlet and exhaust pockets 8, 9 respect1vely spanning the jacket space 7 adjacent to the The outer wall 5 is rovided with a plurality of core supportlng openings 10 which are normally sealed b means of closure plates. A cooling medium supply pipe 13 communicates with the the bottom of the cylinder, and an e ector 11 is, associated with the discharge end of the supply pipe 13 within the 1926. Serial nojieagsse.
jacket space. The ejector 11 has a perfo rated frusto-conical fluid directing discharge Wall' 12 which is preferably directed tangentially of and Within the annular space 7. A cooling medium discharge pipe 1d communicates with the upper portion of the acket space 7 and has a control valve 15 therein which may be either manually or thermostatically controlled. The end of the d scharge pipe 14 is directed into a final discharge tunnel 16 so asto provide a visible indication of the quantity of water passing through and. from the jacket space.
During normal operation of the cooling system, the' cooling medium, preferably water, enters the jacketspace 7 at the bottom through the supply pipe 13 and the ejector ll and the ejector discharge wall 12 directs the entering Water tangentially with respect to the jacket space 7. The entering water by virtue of its high velocity draws other water from within the jacket through the perforations of thewall 12 and produces a thorough circulation of the coolmg medium entirely about the inner wall 4. By properly setting the control valve 15,the quantity of cooling medium discharged from the jacket space 7 through the pipe 14; may be effectively controlled,
and the temperature of the jacket water may thus be accurately regulated. The inlet of cooling water may obviously be effected through one of the holes 10, if so desired, and several supply pipes 13 and ejectors 11 may be provided in case more rapid circulation of the cooling medium within the jacket, is desired. It will be apparent that the invention provides simple and efficient means for automatically and effectively equalizing the temperatures of the cylinder jacket water, with the aid of the diffuser or ejector 11. This ejector by thoroughly circulating the, cooling water entirely around the inner wall 1 and the liner 3, prevents the formation of local pockets within which undesirably heated water might accumulate.
rious modifications within the scope of the claims may occur to persons skilled in the art.
It is claimed and desired to secure by Letters Patent:
1. In combination, inner and outer walls spaced apart to provide a continuous annular jacket, means for admitting fluid to said jacket tangentially thereof and away from said inner wall, and lllfiflS for controlling the quantity of fluid passing through said jacket.
2. In combination, inner and outer Walls spaced apart to provide a continuous annular jacket surrounding said inner wall, means for admitting fluid to said jacket, an ejector for producing a flow of the admitted fluid through said jacket and entirely about said inner wall, and means for controlling the quantity of fluid passing through said jacket.
3. In combination, inner and outer walls spaced apart to provide a continuous annular jacket, means for admitting fluid to the lower )ortion of said jacket, means for causing said fluid to flow in the same direction entirely around said inner wall throughout said jacket, and means for controlling the delivery of fluid from an upper portion of said jacket.
4. In combination, inner and outer walls spaced apart to provide a continuous annular jacket surrounding said inner wall,
the admitted fluid to travel throughout said jacket and entirely around said inner'wall in the same direction, a discharge pipe for said fluid atthe upper portion of said jacket,
and means for controlling the quantity of fluid passing through said jacket.
6. In combination, inner and outer walls spaced apart to provide a continuous annular jacket surrounding said inner wall, means for admitting fluid to the lower portion of said jacket, an ejector for causing the admitted fluid to travel throughout said jacket and entirely around said inner wall in the same direction, a discharge pipe for said fluid at the upper portion of said jacket,
and means associated with said discharge means for controlling the quantity of fluid passing through said jacket.
In testimony whereof, the signature of the inventor is aflixcd hereto.
