Abstract

PURPOSE:To prevent any cavitation at time of cooling fan racing from occurring by making hydraulic fluid flow into the hydraulic inflow side of a hydraulic motor from a reservoir via check valve at a time when pressure at the hydraulic inflow side of the hydraulic motor for cooling fan driving becomes less than a specified value. CONSTITUTION:Hydraulic pressure out of a hydraulic pump 1 to be driven by an engine or the like is fed to a hydraulic motor 3 driving a cooling fan 4, via a flow control valve 2 being controlled by a control unit 7. In an interval between an inflow port 3a and an outflow port 3b of the hydraulic motor 3, there is provided with a bypass pipeline 105 fitted with a check valve 6 permitting hydraulic fluid to flow into the inflow port 3a from the outflow port 3b. When hydraulic pressure at the side of the inflow port 3a goes down by racing of the cooling fan 4, the hydraulic fluid is fed to the inflow port 3a from a reservoir 9 via the check valve 6.
