Abstract

940,475. Liquid cooling systems. SULZER BROS. (LONDON) Ltd. Nov. 11, 1960 [Nov. 24, 1959], No. 39887/59. Heading FIB. A liquid cooling system comprises a fan which is speed-variable independently of engine speed and produces a cooling air flow through a radiator, a radiator by-pass, and a thermostat responsive to the liquid coolant temperature, for controlling both the fan speed and the by-pass flow. Cooling water from a locomotive deisel engine 10, passes via thermostat 21 to radiator 11 and returns via pump 12. The radiator is air-cooled by a hydraulic motor-driven fan 16 supplied from reservoir 19 by pump 18. At low cooling-water temperature a valve 20 controlled by the thermostat 21 in the coolant circuit, opens to by-pass the fan motor 17 to reduce the hydraulic pressure thus stopping or reducing the speed of the fan 16. The pressure change causes a pressure-responsive pilot valve 25 which controls a hydraulic servomotor 15 to open a by-pass valve 14 in the cooling circuit of radiator 11. At higher temperatures, valve 20 is partially closed and increasing hydraulic pressure causes the by-pass valve 14 to close thus causing coolant to circulate through the radiator and causing fan 16 to operate effectively. Specification 897,500 is referred to.
