A pressure control device controls a pressure of fuel supplied from a fuel tank to an engine via a fuel pump. The pressure control device includes a valve device, a first force-applying device and a second force-applying device. The valve device is provided in a path of the fuel from the fuel pump to the engine and comprising a valve and a spring. The valve is movable in an opening direction and a closing direction for permitting and preventing flow of the fuel from the fuel pump to the engine, respectively. The spring applies a first force to the valve in the closing direction. The first force-applying device is operable to apply a second force to the valve in the opening direction depending on the pressure of the fuel supplied from the fuel pump. The second force-applying device is operable to apply a third force to the valve in the opening direction independently of the second force applied by the first force-applying device or independently of the pressure of the fuel used for the first force-applying device.
