Abstract
In a hydraulic system loaded on a working vehicle, an oil pump is fixedly secured to a casing block of a transmission system disposed on a vehicle body as separated from an engine, an input shaft of this oil pump is drivably coupled to an input shaft of the aforementioned transmission system, and a clutch is interposed between the input shaft and a transmission mechanism of the transmission system. Preferably, a control valve is fixedly secured to the oil pump, and a delivery port of the oil pump is directly coupled to an inlet of the control valve. Furthermore, so improved structures of a hydraulic switching valve adapted to be disposed on an outlet side of the control valve is proposed.
