    • A cyclone reservoir for separation of an aerated portion of a hydraulic fluid and a related method of making the cyclone reservoir. The cyclone reservoir includes a lower chamber having a generally cylindrical side wall, a return port, and a suction port. An upper chamber is connected to the lower chamber by a neck section that places the interior volumes of the lower and upper chambers in fluid communication with one another. The neck section has a cross-sectional area taken perpendicular to a central axis of the reservoir that is smaller than a cross- sectional area of the lower chamber and the upper chamber at a different position along the central axis. The chambers and neck section may be made as a single-piece part by molding the reservoir by, for example, rotomolding. A reinforcement band may also go around the neck section to connect and support the upper and lower chambers.
    • 用于分离液压流体的充气部分的旋风存储器和制造旋风分离器储存器的相关方法。 旋风储存器包括具有大致圆柱形侧壁,返回端口和吸入口的下室。 上室通过颈部连接到下室,该颈部将下腔室和上腔室的内部体积彼此流体连通。 颈部具有垂直于储存器的中心轴线截取的横截面面积,其小于沿着中心轴线的不同位置的下腔室和上腔室的横截面积。 腔室和颈部可以通过例如滚塑来模制储器来制成单件部件。 加强带还可以绕颈部部分连接并支撑上部和下部腔室。

    • A reservoir (112/212) for a hydraulic pump system includes a reservoir body (140/240), an inner wall (144/244) dividing an interior of the reservoir body into a first pressure chamber (148/248) and a second pressure chamber (152/252), and a one-way valve (156/256) connecting the first pressure chamber and the second pressure chamber. A piston assembly (180/280) forms a first cylinder portion (184a/284a) connected to the first pressure chamber and a second cylinder portion (184b/284b) that is vented. The piston is movable within the cylinder under the influence of a biasing member (192/292) to increase and decrease the overall volume of the first pressure chamber. The piston pressures a piston pump inlet (172/272) connected to the first pressure chamber and maintains a constant pressure within the first pressure chamber under a variety of piston pump operating conditions.
    • 用于液压泵系统的储存器(112/212)包括储存器主体(140/240),将储存器本体的内部分成第一压力室(148/248)的内壁(144/244)和第二压力室 压力室(152/252)和连接第一压力室和第二压力室的单向阀(156/256)。 活塞组件(180/280)形成连接到第一压力室的第一气缸部分(184a / 284a)和排出的第二气缸部分(184b / 284b)。 活塞在偏压构件(192/292)的影响下在气缸内可移动,以增加和减小第一压力室的总体积。 活塞压力连接到第一压力室的活塞泵入口(172/272),并且在各种活塞泵操作条件下在第一压力室内保持恒定的压力。
