摘要： 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.
摘要翻译：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。

摘要： A pump that includes a piston moveable along a first axis and an eccentric cam positioned about a second axis, wherein the second axis is substantially perpendicular to the first axis. The pump also includes an actuator positioned adjacent to the cam and configured to move the cam along the second axis. In addition, the pump further includes a cam-adjacent bearing positioned between the piston and the cam, wherein the cam-adjacent bearing remains positioned substantially along the first axis upon movement of the cam along the second axis.

摘要： A piston cartridge having a piston chamber, an inlet port, an outlet port, and a piston moveable between a first position and a second position. Also, the cartridge includes a first barrier positioned between the piston and the inlet port and a first sealing member moveable between the first barrier and the inlet port, wherein the first sealing member seals the inlet port when positioned adjacent to the inlet port but allows the fluid into the chamber when positioned adjacent to the first barrier. In addition, the cartridge also includes a second barrier positioned adjacent to the outlet port and a second sealing member moveable between the piston and the second barrier, wherein the second sealing member seals the outlet port when positioned adjacent thereto but allows the fluid to pass through the outlet port when positioned adjacent to the second barrier.
