ing. an outlet 2min the flanges 22, the'innerperipheral wall- I 2- being provided with resilient strips 25. 1 Centrallyof the element I2 there is provided an outlet port26; an inlet port 21- and azdecongealin tube 2-8: Interposed' between the elements ...I I. and I2 as shown in Figs. 1 and 4 are gaskets 255 having an elongated opening 30 and apertures 31, the openings 30 being in alignment with .the outlets I5 and 24, the apertures dhbeing in alignment with the apertures I5 and 23:; As shown in Fig. 1 the elements II and I2 are fixedly secured by bolts 32- and-nuts 33:
Withinthecasing Iii-there is mounted a plurality of tubes 3&- and IiE- illustrated in Fig. 1, the tubes.' 34 having an end portion sfi that-is of hexangular configuration shown in end-elevationzin. Fig. Tandbeing coveredwith a resilient rubber substance 3'1, forming acushioning means. In. Fig. 8:the tubes 35 have an end portion 38 thatis A of substantially quadrilateralconfigurationasshowninend elevation inFig. 8 and being. covered with .a resilient rubber substance 3 9, forming a cushioning means, the. wall being ofv arcuate configuration to conform to. the arc of the inner peripheral walls ofelements II and I2. The ends 36 and 38 of the tubes 34 and 35 being larger than the diameter ofthetubes provide a uniform spacin of the tubes in the casing IIl.
T n-the assembling ofvthe tubes in the housing as shown in Fig, 6 a tube 35,:is placed in the housing It the wall 40. engagin the resilient strips I7. Next one of the tubes sd is placed in the housing It, the wall M of the end portion 36 engaging thev wall. 62 0f the end portion 38. On the opposite side. of the end portion 36 is placed another. tube 35 the end wall 43 engaging the wall Aid of the end portion 38, the arcuate portions :25 engaging the. resilient strip I'I. Tubes are inserted into the casin until the entire inner area of the elements II and I2 are filled, and at this point the. nuts 33 are tightened and the elements brought together. During the tightening of the bolts the ends of the tubes are squeezed together certain portions of some'of the tube ends engaging the resilient strips I! and 25, thus providing leak proof end walls for the cooler. The tubes 3d and 35 in assembled position are in spaced relation and allow oil passing through the channels I3 and 2i into the openings l8, I9 and 20 to pass around the tubes-34 and 35 to the outlet port 28. From the description of the arrangement of parts it can be seen thatv if one of the tubes 34 01 35.should go.bad,.it is a. simple matter to .replacethe tubeby'simplyrlccs connected by a funnel shaped passage 46 through the casing to the port 4'! controlled by a thermostatic valve 43 which is connected by rectangular passage 49 in fitting '50, to which the outlet 26 is also directly connected, to a discharge conduit from the cooler back to the engine. The thermostatic valve fitting 50 forms no part of the present invention and is disclosed merely to clarify the operation of the present oil cooler.
The hot oil from the engine enters the oil cooler through inlet 21 and thence flows around the channel i3 to and through the openings I8, I9 and 20. If the lubricant within the radiator is congealed to such an extent that the resistance to flow through the radiator between the tubes is greater than the resistance to flow through the decongealing tube 28, the lubricant will take the course of least resistance and flow through the decongealing tube28. Thence the oil will flow through passage 46, port 41, passage 49, and finally to a discharge conduit and back to the engine. The thermostatic valve 48 is normally full open, but starts to close as the radiator becomes warmed-up and the temperature of the oil increases. When outlet port 41 is fully closed by thermostatic valve 48, all hot oil is forced through the radiator (between the tubes) and out through outlet 26, passage ii, and thence back to the enine. Just before the outlet port 41 is fully closed by valve 48, hot oil from the engine enters the discharge conduit back to the engine both from the decongealing tube and from core outlet 26.
