Abstract
PURPOSE: To decrease the number of fluid passages by a method or the like wherein one output port of each of a plurality of direction-switching valves which correspond to each other is connected with one input-output port of each of a plurality of the hydraulic-pressure-operated apparatuses by a common fluid passage.
CONSTITUTION: One output port of each of the direction-switching valves 30W32 in plural is gathered into one common port and then connected with one input-output port of each of the hydraulic-pressure-operated apparatuses 34W36 which branch from the common port and correspond to the valves through a rotary joint 33 by a common pipe line 37. Meanwhile, the other output port of each of the switching valves 30W32 is connected with the other input-output port of the corresponding apparatuses 34W36 through separate and independent pipe lines 38W40. When an operating lever 30a is pressed, pressure oil from a pressure source 20 is passed from the port on the left side of the switching valve 30 through the common port and the common pipe line 37 and makes only the apparatus 34 operate.
