Abstract

1,246,395. Cooling I.C. engines; axial-flow fans. CATERPILLAR TRACTOR CO. Sept.22, 1969, No. 46620/69. Headings F1B and F1C. [Also in Division F2] In an engine cooling system wherein a cooling fan 33 is driven by an engine 11 through a hydraulic coupling 55 supplied with oil from the engine under the control of a thermostatic valve 41 responsive to engine coolant temperature, a centrifugally operated valve 65 fast with the turbine drains the coupling when the fan reaches a predetermined speed. Below a predetermined coolant temperature the valve 41 allows a minimum flow through the coupling 55 to cool the latter. An orifice 57 permitting oil to drain from the coupling 55 and return to the engine through a line 59. Above the predetermined temperature the valve 41 is opened to permit an increased flow of oil to the coupling 55 which is filled to provide a drive to the fan 33. When the fan speed reaches the predetermined value the valve 65 opens against the bias of a spring to drain the coupling 55 and thus limit the speed of the fan.
