Abstract: A relatively low pressure hydraulic control system for a high pressure work output system in which a control valve is selectively actuated to position a variable displacement axial piston pump to control the flow in the work output system and to position a directional valve which controls the direction of work output. In such a system wherein two work outputs are provided, thereby requiring two control valves, a priority valve may be utilized in the low pressure system so that a signal from one of the control valves will always override a signal from the other control valve in controlling the axial piston pump.

Abstract: A seat assembly for use in a variety of vehicles, particularly to isolate an operator from oscillatory movements on the vehicle, the operator''s seat being arranged for movement relative to a remote point located below and in longitudinally spaced apart relation from the seat assembly, preferably by means of forward and rearward links pivotably mounting the seat upon a base structure, the rearward link having an effectively greater length than the forward link. A novel fluid circuit is also provided to resiliently resist movement between the seat and a supporting base structure.
Abstract translation: 一种用于各种车辆的座椅组件，特别是将驾驶员隔离在车辆上的振荡运动中，操作者座椅被布置成相对于位于座椅组件下方并且与座椅组件纵向间隔开的远程点运动，优选地由 向前和向后连接的装置可枢转地将座椅安装在基座结构上，后部连杆具有比前向连杆更有效的长度。 还提供了一种新颖的流体回路来弹性地抵抗座和支撑基座结构之间的运动。

Abstract: An improved vehicle seat wherein a bottom cushion assembly is pivotally attached to a back and resiliently mounted upon a base by an oscillation damping member to control oscillation of said vehicle seat with respect to the base. The back is pivotally joined to the base by substantially parallel links which maintain the back at a constant angle of inclination with respect to the base independent of elevational displacement. A swing link, pivotally connecting the bottom cushion assembly to the base permits the bottom cushion assembly to pivot about an imaginary point forward of the seat approximating the knee joint of an operator to minimize movement of the operator''s feet relative to the vehicle. A hydraulic circuit associated with a hydropneumatic suspension for such a seat includes dual damping capabilities for accommodating both normal and high impact loads on the seat.
Abstract translation: 一种改进的车辆座椅，其中底部缓冲组件通过振动阻尼构件枢转地附接到后部并弹性地安装在基座上，以控制所述车辆座椅相对于基座的摆动。 背部通过基本上平行的连接部枢转地连接到基部，其将背部保持在相对于基部的恒定的倾斜角度，而与高度位移无关。 枢转地将底部坐垫组件连接到底座的摆动连接件允许底部坐垫组件围绕靠近操作者的膝关节的座椅的假想点枢转，以使操作者的脚相对于车辆的运动最小化。 与用于这种座椅的液压气动悬架相关联的液压回路包括用于容纳座椅上的正常和高冲击载荷的双重阻尼功能。
