摘要： A power steering system with which no deterioration in steering feeling occurs when a control flow of working fluid changes. A valve mechanism V is made up of a power cylinder control valve CV for controlling a control flow Q and distributively supplying it to a power cylinder C and a bypass control valve BV connected in parallel with the cylinder control valve CV. The bypass control valve BV is normally closed, but while the control flow Q is increasing over a range of from a minimum flow Q.sub.1 to a maximum flow Q.sub.2 available for generating assist force the bypass control valve opens and returns a part of the control flow Q to a tank so that the pressure difference between the pressure chambers of the power cylinder C rises gently and the driver does not experience a disconcerting feeling such as one of the steering wheel suddenly being taken over.
摘要翻译：一种动力转向系统，当工作流体的控制流动改变时，转向感不会发生劣化。阀机构V由动力缸控制阀CV构成，用于控制控制流量Q并将其分配供给到与气缸控制阀CV并联连接的动力缸C和旁通控制阀BV。旁通控制阀BV常闭，但是当控制流Q从最小流量Q1到可用于产生辅助力的最大流量Q2的范围内增加时，旁通控制阀打开并返回控制流Q的一部分使得动力缸C的压力室之间的压力差轻轻升高，并且驾驶员不会遇到诸如方向盘中的一个突然被接管的令人不安的感觉。

摘要： A control device for automatically controlling a pitch angle of a blade includes a hydraulic oil amount calculation unit and an open ratio setting unit. The hydraulic oil amount calculation unit is configured to calculate an amount of hydraulic oil passing through a blade tilt cylinder valve. The open ratio setting unit is configured to cause the blade tilt cylinder valve to open at a predetermined open ratio when a request for the pitch angle to be changed has been received, to cause the blade tilt cylinder valve to close when the calculated amount of hydraulic oil has reached a predetermined amount of hydraulic oil required for the change of the tilt angle, and to cause the open ratio to be smaller than the predetermined open ratio while a request for a predetermined action necessitating that hydraulic oil be supplied from a main valve is being received.
