Abstract

PURPOSE: To reduce a distance required for piping, by connecting a pump to a high pressure chamber of a pump cylinder through a reversing valve attached to an oil tank, thus communicating the oil tank with a low pressure chamber of the pump cylinder which is connected with a low pressure chamber of the pump.
CONSTITUTION: A hydraulic unit 27 having an oil tank 26 integrated with a reversing valve 25 is connected to a dump cylinder 10 to compose a hydraulic system 24. A high pressure chamber of a pump 29 is connected by means of a high pressure pipe 30 and through the unit 27 to a high pressure chamber 21 of the cylinder 10, while a low pressure chamber of the pump 29 is connected by means of low pressure pipes 31, 45 to a low pressure chamber 20 of the cylinder 10 and also to a low pressure port 34 of the unit 27, respectively. In addition, a return oil passage 35 connecting the reversing valve 25 to the low pressure port 34 is communicated with the oil tank 36 through a communicating passage 36.
