摘要： A hydraulic power steering apparatus is provided with a check valve regulating a back flow of a working fluid from a power cylinder mechanism to a hydraulic pump side. A valve element slidably accommodated within a valve body of the check valve has three guide portions protruding to an outer side in a diametrical direction. A valve internal oil path in which the working fluid circulates by a pair of guide portions adjacent in a peripheral direction is formed in the valve element. The guide portion is constituted by a slidable contact portion having a slidable contact surface surface contacted with an inner peripheral surface of the valve body, and a coupling portion coupling a base body portion and the sidable contact portion. A width (W1) in a peripheral direction of the sidable contact surface is larger than a width in the peripheral direction of the coupling portion.

摘要： A damper valve for a hydraulic power steering device is disposed in a hydraulic oil circuit connecting an oil passage changing-over valve in a gear box and left and right oil chambers of a power cylinder. It is provided with a piston valve which is opened by through-flow of hydraulic oil returned back to the oil passage changing-over valve from either one of the left and right chambers of the power cylinder, and a check valve which is disposed in a valve body of the piston valve and which allows only hydraulic oil supplied from the oil passage changing-over valve to either one of the left and right chambers of the power cylinder to flow through the check valve. The piston valve is structured such that a throttle oil passage is formed by through flow of the returned hydraulic oil having an oil pressure of a predetermined value or less, and a fully opened oil passage is formed by through flow of the returned hydraulic oil having an oil pressure of more than the predetermined value. Oil passages for the returned-back hydraulic oil are formed in the valve body of the piston valve.
摘要翻译：用于液压动力转向装置的阻尼阀设置在连接齿轮箱中的油路换向阀和动力缸的左右油室的液压油回路中。设置有活塞阀，该活塞阀由动力缸的左右室中的任一个从油压回流阀返回到油路换向阀的液压油的通流而开启，止回阀配置在活塞阀的阀体，并且仅允许从油路转换阀供应的液压油到动力缸的左室和右室之一流动通过止回阀。活塞阀的结构使得通过具有预定值或更小的油压的返回的液压油的流动形成节流油通道，并且通过流过返回的液压油形成完全打开的油通道，该液压油具有油压超过预定值。返回液压油的油路形成在活塞阀的阀体中。
