A valve mounting mechanism, for mounting a mount valve on a cylinder tube of a hydraulic cylinder, includes: an attachment structure that attaches the mount valve to the hydraulic cylinder; a connection structure that connects a second end part of a hydraulic pipe, whose first end part is connected to the hydraulic cylinder, to a cylinder port of the mount valve; and an adjustment mechanism that adjusts relative positions of a pipe fastening portion, where the hydraulic pipe is fastened to the connection structure, and the mount valve.

Valve mounting mechanism, hydraulic device, and working machine

A work machine includes an engine, a fluid path via which a fuel oil is supplied to the engine, a first filter provided in the fluid path, a pump provided between the engine and the first filter in the fluid path to suck and output the fuel oil, a second filter provided between the engine and the pump in the fluid path, and a third filter provided between the engine and the second filter in the fluid path.

Work machine

A working machine includes a machine body, an operation fluid tank mounted on the machine body, a hydraulic device to be operated by an operation fluid supplied from the operation fluid tank. A valve unit includes a plurality of control valves to control the hydraulic device. The control valves are arranged along a horizontal direction. A switch valve is to be connected to the control valves. A first tube member includes a first fluid tube to connect the control valve and the switch valve to each other and supports the switch valve above the control valve.

Backhoe

The present invention is aimed to provide a working machine provided with: a condenser unit including a condenser of an air conditioner and a cooling fan for cooling the condenser, the condenser unit being disposed in a side of a cabin; and a protection cover covering above the condenser unit, capable of reducing propagation to an operator side of an air intake sound caused by inhalation of air in the protection cover through an air intake vent when the cooling fan causes a wind. In this working machine, each of air intake vents for taking cooling air into the protection cover is formed in an upper surface side of the protection cover and in each of wall parts oriented in a direction opposite to a direction visible from an operator in the cabin.
