摘要： It is designed that an oil pressure signal can be output by operating an operation lever in a twisting direction; a structure can be made simple and its assembly and adjustment are easy; an operation force can be reduced; and a layout is not restricted. It is also designed that when the operation lever is left free after it is twisted, it returns smoothly to the original neutral position. When the operation lever is twisted about the lever axis, the shaft supported by bearings is twisted. The twist of the shaft is converted into the movement in a direction to move the pistons by first and second levers, and the pistons are moved. When the pistons are moved, the oil pressure signal is output from the discharge ports. A disk plate is separated into a first disk plate to which the root of the operation lever is attached and a second disk plate which is tiltably supported by a tilting fulcrum. And, the first disk plate is independent of the second disk plate and twisted about the lever axis of the operation lever.

摘要： The present invention lowers energy loss while at the same time enhancing the responsiveness of a steering control system. When a steering controller is operated rapidly, the aperture area of a steering flow control valve 4 rapidly increases, and the differential pressure (Pp′-PL) across the steering flow control valve 4 rapidly decreases. When the differential pressure (Pp′-PL) across the steering flow control valve 4 rapidly decreases, a flow control valve 6 is biased by the spring force of a spring 6f and quickly moves to the side of a valve position 6b to increase the differential pressure (Pp′-PL) and make it correspond to a set pressure. Thus, the pressure oil of a surplus flow α, which up to this point has been flowing to a discharge oil line 7, is quickly supplied from the flow control valve 6 to a steering hydraulic cylinder 5 via the steering flow control valve 4. Thus, an output Q′ starts quickly relative to an input St.

摘要： A vehicle advances forward while turning to the right when an operating lever is tilted forward and to the right, that is, being operated in a direction intermediate between the forward direction and right-hand direction. Only an output signal of the component corresponding to the forward direction is preserved when the operating lever is released. The component corresponding to the right-hand direction returns to the neutral position, and the signal output is brought to zero. The vehicle therefore moves only forward. The operating position can thus be preserved and a signal output state can be held for a single directional component selected from longitudinal and transverse direction components when operating the operating lever device which is tilted along the directional components in both longitudinal and transverse directions.
摘要翻译：当操作杆向前和向右倾斜时，即在向前方向和右手方向之间的方向上操作时，车辆向右转。当操作杆被释放时，仅保持与前进方向对应的部件的输出信号。对应于右方向的部件返回到中立位置，信号输出为零。因此，车辆只能前进。因此，当操作沿纵向和横向方向上的方向分量倾斜的操作杆装置时，可以保持操作位置并且可以保持从纵向和横向分量中选择的单个方向分量的信号输出状态。

摘要： A high versatility can be obtained, the pipe laying can be configured easily and, by virtue of the fact that a pilot pressured oil is managed, a hydraulic apparatus can be compacted. A differential pressure &Dgr;P between a pressure of the pressured oil on an upstream side and a pressure of the pressured oil on a downward side of operation valves is set to a certain value by a front-to-rear differential pressure stabilizer. As a result, flow rates Q1, Q2 of the operation valves are determined univocally in accordance with opening surface areas (opening amounts) A1, A2 of the operation valves, irrespective of load fluctuations, that is to say, a fluctuation of &Dgr;P. When one of operation members are operated, the opening amount A2 of the other operation valve correspondent with the other operation member is changed in accordance with an operation amount S1 of that operation member, and the other hydraulic actuator correspondent with the other operation valve is driven.

摘要： The aim is to improve operability in vehicles such as skid steer loaders and to reduce the burden on the operator. It is made easy to switch between a first operation pattern wherewith only one operation apparatus of two operation apparatuses is used in driving two actuators, and a second operation pattern wherewith the two actuators are driven using both of the two operation apparatuses. It is made possible to hold operation positions, and to release held positions, whether with an operation lever apparatus that is capable of operation in only one directional component or with an operation lever apparatus that is capable of operation in two directional components in the forward and backward direction and in the left and right direction. When a change to a first combination is designated by a pattern switching lever, the first combination (first operation pattern) is switched to by switching means. This effects correspondences between operation direction signals output from one operation apparatus of two (left and right) operation apparatuses and the drive directions of left and right running actuators. It is thereby made possible to drive left and right running bodies by operating one of the operation levers (the left operation lever). When a change to a second combination is designated by the pattern switching lever, the second pattern (second operation pattern) is switched to by the switching means. Thereby correspondences are effected between the operation direction signals output from the left operation apparatus and the drive directions of the left running actuator, and correspondences are effected between the operation direction signals output from the right operation apparatus and the drive directions of the right running actuator. It is thereby made possible to drive the left and right running bodies by operating both the left and the right operation lever. When a switching valve is switched to a valve position, and the operation lever has been operated so as to tilt, the operation lever is held in that tilted position. And when the switching valve is switched to another valve position, the operation lever holding condition is released.
