摘要： A variable displacement pump is compensated to provide a relatively constant predetermined flow of hydraulic fluid under pressure to an open-center hydrostatic steering system, as the speed of the engine driving the pump varies, and a relief valve by-passes the steering system whenever the steering system would normally reduce the flow to hydraulic apparatus connected in series with and downstream of the steering system.

摘要： A filter thermal bypass valve has an opening defining a seat, a thermal actuator including a plunger capable of being forced toward the seat in response to increases in temperature, a spring retainer capable of movement toward and away from the seat, a rod member affixed to the spring retainer and having an enlarged head portion with a valve plate slidable thereon, a first compression spring forces the retainer in contact with the plunger and a second compression spring urges the valve plate against the seat.

摘要： A rotary agitator for use in sealed containers such as drums having a single bung opening. The agitator is provided with a housing which screws into the bung opening and appending from the housing is a rotating hollow shaft having a helical agitator flight or other agitator member which may be inserted through the bung opening. Material from inside the drum or container may be withdrawn upwardly through the hollow shaft and then outwardly through a port in the housing. A check valve is provided in the housing which communicates with the interior of the container in which to allow pressure equalization in the container which may be connected to a source of inert gas or the like to prevent degradation or other harm to the material in the drum which might be caused by ambient atmosphere.
摘要翻译：一种用于密封容器的旋转搅拌器，例如具有单个开口的鼓。搅拌器设置有一个壳体，该壳体螺旋进入开口并且从壳体附加的是一个旋转的空心轴，其具有螺旋式搅拌器飞行或其它搅拌器构件，该搅拌器构件可以插入穿过孔口。从滚筒或容器内部的材料可以通过空心轴向上抽出，然后通过壳体中的端口向外。止回阀设置在壳体中，该容器与容器的内部连通，容许容器中的压力平衡，该容器可连接到惰性气体源等，以防止对滚筒中的材料的劣化或其它损害这可能是由环境气氛引起的。
