摘要： A pump has a large upper chamber containing an outlet, a smaller lower chamber containing an inlet, a flared transition portion between the lower and upper chambers, a driven vertical impeller extending within the chambers and the transition portion, and an aeration device in the transition portion, the aeration device being a projection into the transition portion with an upward slope facing the movement of the impeller therepast and an edge in the direction of rotation of the impeller, and an air valve controlling air flow through a channel leading into the pump at the edge of the projection.

摘要： An aquarium filter tank pump has a housing with a large upper portion and a small lower portion joined by a transition. A motor driven impeller generally conforming to the inside of the housing draws water into an inlet in the bottom of the lower portion of the housing and discharges it through a generally tangential outlet tube extending from the upper portion and containing an adjustable flow constriction control. A bypass tube extends downward from an opening in the transition so that restriction of flow through the discharge tube controlling pump output is balanced by flow through the bypass tube.
摘要翻译：水族箱过滤罐泵具有上部大的外壳和通过过渡连接的小的下部。通常符合壳体内部的马达驱动叶轮将水吸入壳体下部底部的入口，并通过从上部延伸并包含可调整的流动收缩控制的大致切向的出口管将其排出。旁通管从过渡处的开口向下延伸，使得通过排放管控制泵输出的流量的限制通过旁通管的流动来平衡。

摘要： A check valve for use in a tube has a closure element hinged in the tube which nests within one side of the tube in the open position and pivots to substantially block the tube in the closed position. The closure element has a bottom edge and an upward extending edge which intersect at 90 degrees at the diameter of the closure element, the edges meeting the side of the closure element at points disposed one above the other a distance apart greater than the diameter of the tube. A tubular seat with upper surfaces conforming to the edges of the closure element in the closed position may be inserted below it as a press fit in the tube and the closure element may be hinged to the seat.
摘要翻译：用于管中的止回阀具有铰接在管中的封闭元件，其在管的一侧处于打开位置，并枢转以在闭合位置基本上阻塞管。闭合元件具有底部边缘和向上延伸的边缘，该边缘在闭合元件的直径处以90度相交，边缘在闭合元件的一侧彼此上下距离地设置，该距离大于直径管。在封闭位置中具有与封闭元件的边缘相符的上表面的管状座可被插入其下方，压配合在管中并且闭合元件可铰接到座上。
