    Abstract: Provided is a pump device and a hydraulic actuator that can reduce the number of steps of performance measurement. The pump device includes: a switching valve for switching a flow of oil to a first chamber or a second chamber of a cylinder device, the inside of which is segmented into the first chamber and the second chamber by a piston; an up blow valve (first chamber-side relief valve) that relieves pressure of a first chamber-side flow path connected to the first chamber; and a down blow valve (second chamber-side relief valve) that relieves pressure of a second chamber-side flow path connected to the second chamber.

    Abstract translation: 提供了可以减少性能测量步骤数量的泵装置和液压致动器。 泵装置包括:切换阀,用于将油流切换到气缸装置的第一室或第二室,其内部通过活塞分段成第一室和第二室; 一个减轻连接到第一室的第一室侧流路的压力的上吹阀(第一室侧溢流阀); 以及减轻连接到第二室的第二室侧流路的压力的下吹阀(第二室侧溢流阀)。
