The invention relates to thermostatic control devices for circulatingsystems and is particularly adaptedffor use in regulating the flow of the cooling. medium of an internal combustion engine Thefiiivention has for one of its objects th'e provision of a very simple'construction of control device which is of lightweight and comprises but few parts which may be. readily manufactured and; assembled at a low cost. Other objects of the invention reside in the novel fea tures of construction as more fully hereinafter set forth.
In the. drawings:
Figure 1 is a diagrammatic view of a portion of a motor vehicle including the internal combustion engine. and radiator with my thermostatic control device apph d Figure 2 lsa longitudinal section through the thermostatic control device; Figure 3 is a cross section on the line 3-3 of Figure-2.
applied to a motor vehicle having a watercooled internal combustion engine 1 and the radiator 2, this device being located in the upper water connection between the engine and radiator.
The casing of the thermostatic control devicecomprises the cup-shaped section 3 and ,the cooperating section 4 secured thereto.
The cup-shaped section has th axial opening 5 1n its end surrounded by the cylin' drlcal fiange6 to which an end of one ofthe hose sections of the upper water connection between the engine and radiator issecured by suitable means. The cooperating. casing section 4 comprises the end plate 7 and the intermediate plate 8, the
' end plate having the axial opening 9 with the cylindrical flange 10 surrounding the same and to which anend of one of the hose sections of the upper water connection is securedby suitable means. The intermediate plate 8 is integral withthe end plate 7 and held in spaced parallel relation thereto by means of the integral radial webs 11 extending between the plates. The intermedi- I ate plate is providedfiwiththe radial projections 12 upon its periphervwhich engage intransverse grooves 13 in the inner periphery of the cup-Shaped-sectionB to guide the intermediate plate during the assembly and securing together of the section. With the I arrangement as thus far set 'forth, the en- My thermostatic control device is, shown 'gine cooling medium, such as water, enters the casing-of the thermostatic control device through the opening 9 in the end plate '2", passes through the :radial or transverse pas sage between thefplate 7 and intermediate plate 8 then passes-between the peripheries of the intermediate plate 8 and the shaped section 3'into that portion of the cup-shaped section beyond the intermediate plate and finally out through the opening 5 in the end of the cup-shaped section.
To secure the cooperating section 4 of thecasing to the cupshaped section 3, the end of the inner periphery of thelatter'is chined to forman/ann'iilar shoulder 1% against which the end plate 7 of the coope ating section abuts, this end plate having a press-fit within the machined portion 'to form a water-tight seaL, The shoulder posimedium as its temperature rises and falls;
I have provided the freely'movable annular. thermostatic valve 15 having overlapping ends and mounted upon the cooperating casing' section 4. The adjacent faces of both the end plate 7 and intermediate plate 8 are formed with corresponding annular shoulders16 and 17 respectively forming seats engageable 'by the thermostatic valve.
tits"- As. the temperature of the water entering thethermostatio control device increases, this thermostatic valve expands so that its diameter becomes greater than the diameter of the intermediate plate, at which time a portion of the water is allowed to 'pass through the thermostatic control device. As the temperature of the water increases and t-he" expansion of the thermostatic valve increases, its diameter continues to increase until it lies adjacent to theinner periphery of the cup-shaped section 3, it being guided by means of the radial-projections upon the intermediate plate and the end plate. Since v these radial projections extend into grooves in the cup-shaped section, the thermostatic valve cannot engage between the ends of these radial projections and the inner periphery of the cup-shaped section.
*Both the cupshaped section and the cooperatingsection ot the casing are pretcn ably die cast so-that as'a consequence titre cost of manufacture oat these parts is considerahly decreased. Furthermore, the ma- -chining operations upon both the sections are small in number and very simple, and their assembly may be readily accomplished at a small cost Still another feature is that the Weight of the device is relatively small so that no support other than that afforded by-thehose sections on": the upper Water connection is, necessary. I What I claim as my invention is: -1. In a thermostatic control device, the combination with a casing comprising a secj tion having a passage therein, a second section' secured to said first-mentioned sectioh and having a passage therein extending transversely oi said, first-mentioned passage and adapted to communicate therewith, and

combination with a casing comprising a section having a passage therein and a second section secured to said first mentioned section and comprising an end plate and an 3o; intermediateplate spaced from said end plate and located within said first-mentioned section, said intermediate plate having a portion of its periphery spaced from the nterior periphery of said first-mentioned '35 section, and a thermostaticvalve cooperating with said endand intermediate plates for controlling communication between the I spaceintermediate said plates and'the passage in said first-mentioned section.
3. In a thermostatic control device, the
