Abstract

1408880 Hydrostatic transmissions LUCAS INDUSTRIES Ltd 11 Jan 1973 [18 Dec 1971] 58915/71 Heading F2W [Also in Division F1] In a fan drive system in which variable capacity hydraulic motors 3 connected in parallel with a pump 1 drive fans 4, the capacity of each motor 3 is varied by a servo 5 which taps pressure from between a fixed throttle 7 and a throttle 8 which is varied by a temperature sensor 9, so that the motor capcity and thus speed of each fan is varied depending on the temperature at the respective sensor 9. Relief valves 13, 14 maintain a constant pressure in the circuit to the motors 3 and a feed pump 11, a cooler 15 and a filter 12 are also provided.
