Document Type and Number:
WIPO Patent Application WO/2017/169550
Kind Code:
A1
Abstract:
Provided are a tilt control device that precisely transmits the movement of a spool of a control valve to a driving cylinder and achieves highly precise tilt control and a hydraulic rotation device including same. A tilt control device 1B controls the tilt of a variable displacement type rotation machine. The tilt control device 1B is provided with a housing 1H, a movable member 20, a spool 222, and a first position adjusting mechanism 2. The movable member 20 is connected to the eccentric ring of the rotation machine and allowed to move in the axial direction. The movable member 20 is provided with a connection part 21 and a tubular sleeve part 22. The spool 222 moves in the tubular inside of the sleeve part 22 in the axial direction. The first position adjusting mechanism 2 moves the spool 222 in the axial direction. The movable member 20 and the housing 1H form a driving cylinder that moves the eccentric ring, and the movable member 20 and the spool 222 form a control valve.
