FLUID-CONTROLLING MEANS.
Application filed March 7, 1927. Serial No. 173,541
This invention relates to cooling systems for internal combustion englnes and its primary object is to provide a fluid controlling means therefor whereby the circulation of the cooling fluid is automatically controlled in consistency with the temperature of the fluid.
A further object of the invention is to provide a fluid controlling means for the cooling system of an internal combustion engine, which functions independently of the engine speed and controls the circulation of the cooling fluid for the engine in accordance with the temperature conditions.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and. specifically pointed out in the appended claim.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a diagrammatic view illustrating the application of my invention to an internal combustion engine.
Figure 2 is a fragmentary viewshowing the fluid pump thereof.
Figure 3 is a vertical sectional view taken through a portion of the engine and showing the thermostat and its association with the rheostat both ofwhich form. a part of my invention.
' Figure 1 is a sectional view taken. on line 14 of Figure 5.
Figure 5 is a sectional view taken on line 5-5 of Figure 3.
Referring to the drawings in detail the letter A'indicates an internal combustion engine of the usual. construction and B the radiator of the cooling system thereof.
Secured to the front of the engine A and being in communication with the water jacket of the latter and radiator B respectively is the casing 1 ofa fluid pump 2. Passing-through the casing and arrying the blades of the pump 2 is a shaft 3 having fixed to its outer end the fan 4,.and disposed. between the ends of said shaft is a pulley 5 having trained thereabout a. belt 6 which is likewise trained about a similar pulley 7 secured to the shaft of an electric 'motor.8 whereby said motor will operate the pump as will be readily apparent,
The means I employ for-controlling the operation of the motor 8 includes a thermostat 9 mounted in a housing 10 threadedly secured in one side wall of the Water jacket of the engine in a manner whereby the inner portion of the housing 10 will be in. direct contact with the cooling fluid in the water jacket. The thermostat 9 has secured to one portion thereof a rod ll-which is guided by an annular flange 12 formed in the closure member of the thermostat housing and said rod 11 has its'outer end frictionally secured to a link 13 which in turn is pivotally secured to. an arm 1 1 fixed to' the outer end. of a shaft 15 which has securedthereto the lower end of the contact member 16 of a rheostat. The rheostat is in electricaliconnection with the motor 8 through the medium of the conductor 17.
. From the above description and disclosure in the drawings, it will be obvious that the temperature of the fluid in the water jacket of the engine as shown will control the operation of the mot-or 8 due to the thermostat 9 and its operative connection with the rheostat 18 and which will move the contact member 16 with respect to the resistance unit 19 of the rheostat and thereby cause varied operation of the motor 8, it depending of course upon the temperature of fluid in the water jacket. I have also provided a switch 20 arranged in convenient reach of the driver of the motor vehicle as suggested in Figure 1 whereby the current from the battery can be controlled to the rheostat as well as the motor 8 through the medium of the conductors 22, 23 and 24.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it 'to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
VVha-t claim is:
The combination with an internal combustion engine and its cooling system, together with the radiator of the latter, of a fluid pump in communication with the fluid jacket of the engine and radiator respectively, an electric motor supported by the engine, means between said electric motor and pump g I I 1,009,723
