E. OPFERKUCK WATER CIRCULATING SYSTEM FOR INTERNAL COMBUSTION ENGINES Filed June 19. 1922 Nrr sr'rEsA're'r Patented Sept. 4, 1923.
EMIL OPFERKUCIQ OF SPRINGFIELD, OI-IIO, `ASSIGNOR TO THE SUPERIOR GAS ENGINE 'i COMPANY, OF SPRINGFIELD. OHIO, A CORPORATION OF OHIO.
WATER-CIRCULATING SYSTEM FOR INTERNAL-COMBUSTION ENGINES.
Application filed .Tune 19,
To all whom it may concern:
Be it known that I, EMIL OPFERKUCK, a citizen of the United States, residing at Springeld, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Water-Circulating Systems for Internal-Combustion Engines, of which the following is a speci,
ication.
This invention relates to improvements in internal combustion engines of the type in which air for scavenging and fuel mixture purposes is compressed by the working stroke of the piston, and it particularly relates to means forutilizing the compressed air for creating a more effective circulation of cooling water through the water jacket of the engine.
The obje-ct of my invention is to provide, in an engine which employs the thermo-syphon system of circulation for the cooling water,'means for assisting the circultion of the water which consists in utilizing the air pressure created by the piston.
A more specific object of the invention is to utilize this air pressure for the purpose stated in a way which will be extremely simple in character and eective in operation.
'In the drawings, the view is a longitudinal section of so much of an internal combustion engine as is necessary to illustrate the improvements, showing my invention applied thereto. v
The engine shown is of the two-cycle type, 1 representing the cylinder; 2 the hollow piston; 3 the water jacket about the piston; 4 the removable head having the combustion chamber, hot ignition member 5 and fuel nozzle 6; 7 the water jacke-t Jfor the head; 8 a removable chambered plate which communicates with the water jackets 3 and 7; 9 an air chamber about the rear end of the cylinder; 10 an air supply port in which is located a check valve (not shown); 10 an air inlet port leading from ythe air chamber to the cylinder; 12 an exhaust port leading from the cylinder to the water jacket exhaust pipe 13; 14 water supply pipes leading `:from the tank 15 tothe water jacket; 16, and 17 and 18 sections of the water discharge pipe leading from the 1922. Serial No. 569,477.
water jacket to the watery tank and connected by the tees 18 and 19.
Connected with the air chamber 9 `is a vertical pipe 21, the upper end of which communicates with the body 22 of a regulating stop check valve in which 23 represents the valve seat and 24 the valve, the hollow stem 23 of which receives the lower end of a threaded stem which may be adjusted to regulate the opening movement of the valve. Leading from the body 22 is a horizontal pipe 26 which communicates with the tee 19. Communicating with the upper end of the tee 2O is a riser or standpipe 27 having its upper end open to the atmosphere.
The operation of the device is as follows: In the event the parts become too hot, which sometimes happens under certain running conditions of the engine, the valve 22 is releasedfrom its seat by turning out the threaded stem whereupon, upon each working stroke of the piston, which compresses air in the chamber 9, air will be forced through the pipes 21 and 26 and valve body 22 into the water discharge pipe, thus applying air pressure to the water and increasing the rapidity of circulation `thereof, this air escaping Ifrom the riser or standpipe 27. By adjusting the threaded stem 25, the amount of air ypressure may be nicely regulated so as to secure the necessary rapidity of circulation of the cooling water and thereby maintain the temperature of the engine at the most eiiicient degree of heat. The valve 24 acts as a check valve to prevent back pressure and the entrance of water into the air chamber 9.
Having thus described my invention, I claim:
1. In an internal combustion engine, the combination, with the cylinder, of a water jacket, an air chamber located about one end ot the cylinder in which air is compressed upon each working stroke of the piston, a water discharge pipe leading from the jacket, and an air pipe forming a communication between said air chamber and said water pipe, and means for preventing back pressure in said air pipe and for regulating the amount of air passing therethrough.
2. In an internal combustion engine, the
combination, with the cylinder, of a Water jacket, an air chamber located about one end of 'the' cylinder in Wh'ch'air isy compressed*uponA each Work-ing" stokefof the 5 piston, a Water discharge pipe leading from the jacket, and an air pipe forming a cominl'inicationvbetween said airehamber and said Water pipe, and a valve kin said air pipe to prevent back pressure and to regulate fthe amount of Tvail" #passing ytherethrough. y Y' In testimony whereof,
I lhave heeuntol `*set my hand vthis 113th dayl of, June, 1922..
