<p>PROBLEM TO BE SOLVED: To provide a hydraulic machine that can be downsized by improving the layout of valves, and a wind power generation device including the same.SOLUTION: A hydraulic machine comprises: pistons; cylinders; oil supply valves 60A for switching the state of supply of hydraulic oil to hydraulic chambers 25 respectively; and oil discharge valves 60B for switching the state of discharge of hydraulic oil from the hydraulic chambers respectively. Each oil supply valve and each oil discharge valve include: valve elements 62A and 62B; movable shafts 63A and 63B connected to the valve elements; and drive parts 64A and 64B configured to move the movable shafts respectively. A first movable shaft, which is one of the movable shaft of the oil supply valve and the movable shaft of the oil discharge valve, is inserted into a through-hole 69 provided in a second movable shaft, which is the other of the movable shaft of the oil supply valve and the movable shaft of the oil discharge valve. The first movable shaft and the second movable shaft are configured to be able to be moved by the drive parts independently of each other.</p> |
