DUAL TEMPERATURE COOLING SYSTEM FOR MOTORS Filed Feb. 26, 1931 v 'I'hermos'l-wk J b ZBraZaker Patented June 12, 1934 UNITED STATES PATENT OFFICE DUAL TEMPERATURE COOLING SYSTEM FOR MOTORS 8 Claims.
This application is a continuation in part of my pending application Ser. 490,722 filed October 23, 1930.
The object of my invention is to provide an improvement in cooling systems for automobile engines adapted to be controlled by thermostats or automatically in any suitable manner, through the use of dual temperatures.
I attain these and other objects 0! my invention 0 by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of one form of my invention; and
Fig. 2 is a perspective view of another form of my invention.
Like numerals designate like parts in each of the views.
Referring to the accompanying drawing, there is illustrated a cylinder block 1 containing the engine cylinders, around which the water circulates. There is also illustrated a radiator having the usual upper reservoir 3, an intermediate cooler section 2, a vertical partition 5 and a hot section 4 and the usual open cold reservoir 6 at the bottom of the radiator which is in communication with both sections 2 and 4.
I provide a return conduit 7 leading from the radiator to the cylinder block 1 and in connection with this conduit provide a suitable pump 8 which is shown diagrammatically and which may be driven by any suitable means from moving parts of the motor.
I provide a conduit 9 communicating with the motor casing at the rear end thereof and extending to the upper portion of the radiator and communicating with the upper reservoir 3.
I provide a conduit 10 extending from the cylinder head directly to section 4 of the radiator as shown in Fig. 1, and in connection with conduit 10 I provide a suitable thermostat and valve controlled thereby, designated as 11, shown diagrammatically, to control the flow of hot water from the cylinder head to radiator section 4. The thermostat is preferably set to open for operation at a temperature of about 150 F.
In operation the water from reservoir 8 and cold section 2 of the radiator flows downward into the reservoir 6 and thence through conduit '1 into the cylinder block 1 and from the cylinder block; 1 through conduit 9 back to the upper reservoir 3 maintaining a constant circulation.
When, however, the temperature of the water rises in the cylinder head to the predetermined degree for which the thermostat is set, to open 55 the hot water will flow through conduit 10 mm the hot section 4 of the radiator and thence into reservoir 6 and back through conduit 7 to the cylinder block, being cooled by its passage through the radiator. In this form of my invention a dual system of cooling is substantially no maintained.
Referring to Fig. 2, there is illustrated a modification of the invention in which the partition 5 is eliminated and the cold section 2 extends entirely across the radiator. In this form 55 of the invention a less satisfactory control of the temperature of the water circulating in the motor is attainable.
In the form of the invention illustrated in Fig. 2 of the drawing, when the temperature of 7 the water in the cylinder head rises to the predetermined temperature for which the thermostat is set to open, the hot water in the cylinder head will flow through conduit 10 into the upper reservoir 3 and there be mingled with the cool water which has flowed in through conduit!) and cooled thereby, and the water at a cooler temperature will be returned through conduit '7 to the cylinder block. It will be noted that no water passes through the conduit 10 in either form of go the invention until the thermostat operates to open a suitable valve in the conduit; while a constant circulation 01' water is carried on through conduits 7 and 9 to and from the cylinder block and from and to the radiator. When the g5 temperature of the water in the cylinder head (since the hot water will rise to the head of the motor casing), rises to the desired degree for which the thermostat is set, a valve is opened automatically and the water flows through conduit 10 into reservoir 3 and thence through radiator section 4 to reservoir 6 and thence through conduit 7 back to cylinder block 1, thereby automatically controlling the cylinder head temperature oi the cooling system to the degree desired for best combustion results.
It is contemplated that a partition in the radiator be. provided as described as, if and when necessary, but in many radiators each channel is separate and do not require a partition.
What I claim is:-
1. In a dual temperature cooling system for internal combustion motors, the combination of two cooling systems including a cylinder block, a cylinder head, and a radiator, one of said cooling systems comprising the cylinder block having an outlet conduit from its water jacket to one section of the radiator, the other of said systems comprising the cylinder head having an outlet conduit from its water jacket to a separate section of the radiator; the cylinder block and the cylinder head having a common intake conduit from the radiator to the water jacket of the cylinder block.
