Abstract
811,900. Cooling engines. VOITH, G.m.b.H., J. M. March 4, 1957 [March 2, 1956], No. 7110/57. Class 7(2) [Also in Group XIII] In a cooling system for an internal combustion engine, in which hot engine coolant liquid is cooled in passing through a radiator over which cooling air is blown by a fan and in which louvres are provided to regulate the air flow across the radiator, a control device is actuated by the temperature of the engine coolant liquid such that as a predetermined minimum temperature of the liquid is exceeded, firstly the louvres are fully opened and only on a further rise in temperature of the liquid is the fan brought into operation, the fan speed being increased as the liquid temperature rises. When the liquid temperature starts to fall, the fan speed is gradually reduced with the fall in temperature until the fan ultimately is stopped and only thereafter are the louvres closed. In the form shown a fan 5 and louvres 2 are associated with the cooling radiator 1 of a Diesel engine, and are controlled by a thermally sensitive element 13 located in the duct 1c by which hot liquid from the engine passes to the bottom header 1a of the radiator. As the temperature of the liquid in duct 1c rises resultant expansion of liquid in the element 13 acts upon a piston 12 moving the same against the action of a return spring 14. thereby allowing the louvre actuating piston to be acted upon and lifted by air pressure from a duct 21 whereupon the louvres 2 are at once fully opened. Further movement of the piston 12 in the same direction on a further rise in the temperature of the liquid in pipe 1c, causes collar 18 to act on abutment 18a of a sleeve 17 and to move the sleeve in the same direction as the piston is moving. Such movement causes rotational movement of a toothed wheel 19b which moves the scoop tube 10 of a fluid coupling to a position in which the fan commences to rotate. Further movement of the piston 12 then causes an increase in the speed of the fan. If the temperature of the liquid in pipe 1c commences to fall the piston 12 moves in the opposite direction under the influence of return spring 14, the fan speed being decreased and the fan ultimately stopping, before the louvres are closed.
