    • A hydraulic device includes a hydraulic pump, valve stack, interface tube, and upper and lower seals. The valve stack has a pressure balanced connecting with an interface tube receiving bore. The interface tube conveys a hydraulic fluid from the hydraulic pump to the valve stack and has an axial bore open at a first end and closed at a second end with an outlet proximal to the second end. The upper seal seals the interface tube in the interface tube receiving bore and is disposed annularly about the interface tube between the outlet and the second end. The lower seal seals the interface tube in the interface tube receiving bore and is disposed annularly about the interface tube proximal to the outlet and between the outlet and the first end. The upper seal and the lower seal balance a pressure of the hydraulic fluid from the outlet.
    • 液压装置包括液压泵,阀组,接口管以及上下密封。 阀组具有与接口管接收孔连接的压力平衡。 接口管将液压流体从液压泵传送到阀组,并且在第一端处具有敞开的轴向孔,并在第二端处封闭,并具有靠近第二端的出口。 上密封件密封接口管接收孔中的界面管,并且围绕出口和第二端之间的界面管环状设置。 下密封件密封接口管接收孔中的界面管,并且围绕接口管环形地设置在出口附近以及出口与第一端之间。 上密封件和下密封件平衡来自出口的液压流体的压力。

    • An actuator is provided. The actuator includes a rod having a socket portion at one distal end of the rod and a swivel cap. The swivel cap includes a base portion having an inner surface and an outer surface and a raised domed portion disposed on the inner surface of the base portion. The outer surface has an origin of the radius at the center of the plane that defines the outer surface of the base portion. The raised domed portion is mounted on the socket portion of the rod and has an origin of the radius on the plane that defines the outer surface of the base portion. A raised region is located on at least one of the raised domed portion or the socket portion. The swivel cap tilts relative to the rod in response to angular misalignment with a load to a tilt angle.
