Abstract: A tilt cylinder for tilting an outboard engine has first and second cylinder chambers. A pair of on/off valves is movably disposed in respective fluid passages connected to a hydraulic pump and the first and second cylinder chambers, respectively. The on/off valves are operatively combined with respective shuttle valves which have respective oil passages in facing relationship to the on/off valves, respectively, and respective ball valve bodies for selectively opening the oil passage into communication with each other. When the hydraulic pump is actuated to develop a working oil pressure buildup, one of the on/off valves is opened by the working oil pressure buildup to establish an oil supply passage from the hydraulic pump to one of the first and second chambers, and the other of the on/off valves is opened by the coacting shuttle valve which is moved by the working oil pressure buildup to establish an oil return passage from the other of the first and second chambers to the hydraulic pump. The shuttle valves have respective auxiliary passages communicating with the oil passages, respectively, and the oil supply and return passages, respectively.

Abstract: A power steering device for use with a boat propulsion unit has a hydraulic cylinder unit for angularly moving a steering arm of the boat propulsion unit. A rotary valve mechanism for supplying working oil from a working oil tank to the hydraulic cylinder unit and discharging working oil from the hydraulic cylinder unit to the working oil tank comprises a flat valve body having oil holes defined transversely therethrough and a valve housing assembly housing the flat valve body and having ports defined therein for communication with the oil holes, the ports being connected to the working oil tank and the hydraulic cylinder unit. The power steering device also includes a steering shaft for operating the rotary valve mechanism in response to a steering action. The hydraulic cylinder unit, the rotary valve mechanism, and the steering shaft are integrally joined to each other.
