摘要： A method of automatically setting an auxiliary hydraulic valve's flow rate and returning to that flow rate automatically is disclosed. The work vehicle such as a backhoe has two hand controls, one of which has a button, and the other has a thumb wheel. To set the hydraulic flow rate, one both presses the button one hand control and moves the thumb wheel on the other hand control until the proper flow rate is reached. At this point, both button and thumb wheel are released. This causes the flow rate to be saved in RAM or ROM memory. The flow rate can be varied at any time by rolling the thumb wheel up or down. One can return to the previously save flow rate by pressing the button. Both controls are preferably spring loaded.

摘要： A rotary fluid swivel for use with a cab heating system of a large construction vehicle is disclosed. The cab of the vehicle may be rotated through 360 degrees with respect to the vehicle frame. The cab heating system utilizes heated fluid from an engine mounted within the frame. The heated fluid must pass into the cab to heat the cab and must then be returned back to the engine. The rotary fluid swivel consists of a first fixed boss portion extending upwardly from the vehicle frame and a second spindle portion mounted to the cab. The spindle portion is rotatable about the boss portion and includes several channels. The boss portion includes a central conduit for passage of fluid from the engine to the cab heating unit and an outer conduit for return of the fluid to the engine. Branch conduits extend outwardly from the return line to the channels within the spindle to provide sealing fluid that will also create a fluid bearing and will cool the outer periphery of the boss, thus preventing the boss from deforming to an undesirable extent.
摘要翻译：公开了一种用于大型施工车辆的驾驶室加热系统的旋转流体回转装置。车辆的驾驶室可以相对于车架旋转360度。驾驶室加热系统利用来自安装在框架内的发动机的加热流体。加热的流体必须通入驾驶室以加热驾驶室，然后必须将其返回发动机。旋转流体旋转体由从车架向上延伸的第一固定凸台部分和安装到驾驶室的第二主轴部分组成。主轴部分可围绕凸台部分旋转并且包括多个通道。凸台部分包括用于将流体从发动机通向驾驶室加热单元的中心导管和用于将流体返回到发动机的外部导管。分支管道从返回管线向外延伸到主轴内的通道，以提供密封流体，其也将产生流体轴承并且将冷却凸台的外周边，从而防止凸台变形到不期望的程度。

摘要： A system for automatically moving a stabilizer of a work vehicle is disclosed. A joystick is connected to an electronic controller, which in turn, is connected to valve drivers to drive stabilizer raising and lowering valves. In one mode of operation, the controller is programmed to move the stabilizers up or down at a rate that is proportional to the deflection of the joystick from a neutral position. If the operator holds the joystick in a certain position or range of positions, the controller enters a second mode in which it automatically raises the stabilizers even if the joystick is released. The stabilizer can be placed in a third mode of operation by moving the joystick rapidly back and forth. When the operator does this, the controller is configured to reduce the ramp rate or damping of its response to joystick movement.

摘要： The invention provides a system for regulating pressure equalization in hydraulic mechanisms to suppress oscillation in heavy equipment. The system includes a first and second hydraulic lines, a crossover valve in communication with each of the first and second hydraulic lines, a timing system in communication with the crossover valve, and a motion detector in communication with a heavy equipment component. The motion detector senses a linkage motion and operatively opens the crossover valve, which remains open as directed by the timing system.

摘要： A work vehicle includes a frame, an excavating apparatus movably secured to the frame, an operator's station, and a control system. The excavating apparatus includes a material engaging member and a plurality of actuators having positions for positioning the material engaging member with respect to the frame. The control system controls the positions of the plurality of actuators and thereby the position of the material engaging member. The controls system includes a plurality of manual operator input devices, an operator presence sensor, a control circuit, and an override device. The plurality of manual operator input devices are located at the operator station for providing material engaging member position commands. The operator presence sensor is configured to generate an operator presence signal. The control circuit is configured to receive the operator presence signal, to enable the providing of material engaging member position commands when the operator is disposed at a first operator position and to disable the providing of material engaging member position commands when the operator is away from the first operator position. The override device bypasses the presence sensor and is manually engagable by the operator. The control circuit is configured to enable the providing of material engaging member position commands when the override device is manually engaged.
