摘要： A rotary actuator includes a central housing; an output shaft that extends through the central housing; a vane that is mechanically coupled to the output shaft and divides the central housing into a first chamber and a second chamber; and a flow control mechanism that is moveable within the central housing and including a high pressure port and a low pressure port for communicating hydraulic fluid into and from the first and second chambers. The flow control mechanism is moveable to position the high pressure port and low pressure port relative to the first chamber and the second chamber for communication of the hydraulic fluid, thereby generating a pressure differential across the chambers. The vane rotates within the central housing in response to the pressure differential, and rotation of the vane drives the output shaft. A motor is configured to receive control signals to drive the movement of the flow control mechanism.

摘要： Example embodiments may relate to a robotic system that includes a hydraulic actuator and an electric actuator both coupled to a joint of the robotic system. Operation of the actuators may be based on various factors such as based on desired joint parameters. For instance, such desired joint parameters may include a desired output torque/force of the joint, a desired output velocity of the joint, a desired acceleration of the joint, and/or a desired joint angle, among other possibilities. Given a model of power consumption as well as a model of the actuators, the robotic system may determine operating parameters such as hydraulic and electric operating parameters as well as power system parameters, among others. The robotic system may then control operation of the actuators, using the determined operating parameters, to obtain the desired joint parameters such that power dissipation in the system is minimized (i.e., maximizing actuation efficiency).

摘要： An electro-pneumatic tool drives a fastener into a workpiece by energizing an electric motor to drive a first piston and generate compressed air in a first cylinder. The compressed air is then supplied to a second cylinder and causes a second piston to move and drive the fastener into the workpiece. After the first piston has passed through its top dead center, braking is applied to the first piston according to one or more braking parameters. Then, if a control unit determines that the first piston has come to a stop at a position that is outside a predetermined range about the bottom dead center of the first piston, one or more of the braking parameters is changed in a subsequent fastener driving cycle to cause the first piston to stop closer to its bottom dead center after conclusion of the subsequent fastener driving cycle.

摘要： A lifting mechanism is disclosed which is operated hydraulically and is configured to be mounted or used on a mobile working machine. The lifting mechanism or its hydraulics have a relieving pressure limiting valve which can be regulated as a function of the ground profile. For this purpose, a directly or indirectly measuring sensor arrangement is provided. Furthermore, a method is disclosed which serves for regulating a relieving pressure of a lifting mechanism of a mobile working machine. The method has the following steps (i) detection of the ground profile via a sensor arrangement, and (ii) limitation of the relieving pressure of a relieving line by setting an opening pressure of an electronically activatable proportional relieving pressure limiting valve via a control unit as a function of signals from the sensor arrangement.

摘要： A spool for a servovalve. The spool includes a first end land and a second end land. The spool includes an intermediate land having a first side and a second side opposite the first side. The intermediate land is positioned between the first end land and the second end land in a spaced-apart, axially aligned relationship such that a first annular space is defined between the first end land and the first side of the intermediate land and a second annular space is defined between the second end land and the second side of the intermediate land. The intermediate land further includes at least one fluid passageway formed in and extending through the intermediate land from the first side to the second side to establish fluid communication between the first annular space and the second annular space to provide a fluid pressure feedback between the first and second annular spaces.

摘要： A control device for the position control of a hydraulic cylinder unit has a controller which receives a set and an actual piston position and determines a preliminary manipulated variable based on the difference of the set and actual positions. A linearization unit multiplies the variable with a linearization factor and outputs it to the valve control unit so that the piston is adjusted at an adjustment speed. The linearization unit determines the factor dynamically as a function of the actual piston position and of working pressures that prevail at both piston sides. The linearization factor is determined such that a ratio of the adjustment speed to the difference of the set and actual positions is independent of the actual position and the working pressures. In the specific case where the controller is configured as a P controller, the order of the controller and the linearization unit can be reversed.
摘要翻译：用于液压缸单元的位置控制的控制装置具有控制器，其接收组和实际活塞位置，并且基于设定位置和实际位置的差确定初步操纵变量。线性化单元将变量与线性化因子相乘并将其输出到阀控制单元，使得活塞以调节速度被调节。线性化单元根据实际的活塞位置和两个活塞侧面的工作压力动态地确定该因子。确定线性化因子，使得调整速度与设定位置和实际位置的差值的比率与实际位置和工作压力无关。在控制器配置为P控制器的具体情况下，可以颠倒控制器和线性化单元的顺序。
