    摘要: A fan drive system is provided that is hydraulically controlled having an electrical failure mode wherein midrange operation of the fan drive system is maintained. Accordingly, in the failure mode, a fan drive system hydraulic relief valve is not closed thereby ensuring a degree of operation of the fan drive system even during periods of electrical failure.
