徴とする漁船用油圧源。 A variable displacement pump equipped with a discharge amount control device and a maximum discharge pressure control device is connected to the main engine of a fishing boat, and pressure oil is supplied from the variable displacement pump to a hydraulic actuator mounted on the fishing boat. The variable displacement pump is directly connected to the main engine, and a first pilot circuit for introducing pilot pressure for controlling the discharge amount control device is branched to a discharge circuit connected to the first hydraulic actuator of the variable displacement pump. A second pilot circuit is branched off from a point closer to the variable displacement pump than the branch point, and further leads a pilot pressure for controlling the discharge amount control device and the maximum discharge pressure control device,
A hydraulic power source for a fishing boat, characterized in that a variable orifice and a two-way switching valve are provided in a discharge circuit between branch points of a pilot circuit.
