摘要： An apparatus includes a plurality of pneumatic linear actuator modules, a dynamic actuator linkage, and a static actuator linkage. Each of the plurality of pneumatic linear actuator modules includes a static portion and a dynamic portion. The dynamic portion is movable in a linear fashion relative to the static portion. The dynamic actuator linkage connects the dynamic portion of each of the plurality of pneumatic linear actuator modules to a moveable portion of a device. The static actuator linkage connects the static portion of each of the plurality of pneumatic linear actuator modules to an immoveable portion of the device. A number of pneumatic linear actuator modules one less than the plurality of pneumatic linear actuator modules are able to provide linear actuation to the device. Each of the plurality of actuator modules is configured to selectively couple and decouple to the dynamic actuator linkage and the static actuator linkage.

摘要： A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

摘要： A machine press is provided in which at least one hermetically sealed hydraulic drive unit is switchable from a working mode, in which a base pressure above ambient pressure is continually exceeded, into a rest mode. To this end, in parallel with a pressure converter, to the high-pressure side of which a pressure store and a raising working chamber of a cylinder piston unit are connected, a bypass is provided, having a first blocking valve that is controllable by a control unit and, in its blocking position, blocks the through-flow direction from the high-pressure side of the pressure converter to the low-pressure side. Furthermore, the low-pressure side is connectable to a lowering working chamber via a second blocking valve controllable by the control unit. The pressure output of the hydraulic unit is connectable to the raising working chamber via a third blocking valve controllable by the control unit.

摘要： An electropneumatic positioner for a pneumatic actuator to operate a control device of a processing plant can include two modular pneumatic slots and a pneumatic control output. The two modular pneumatic slots can engage with a respective modular pneumatic component. The two pneumatic slots and the pneumatic components can be modularly matched to one another such that their respective pneumatic interfaces merge into one another when a pneumatic slot is engaged. The pneumatic control output can output a pneumatic control pressure signal to the pneumatic actuator. The two modular pneumatic slots and the pneumatic control output can form a pneumatic series connection.

摘要： An example robot includes movable members, a hydraulic system including at least (i) hydraulic actuators configured to operate the movable members, and (ii) a source of hydraulic fluid, and a controller. The controller may be configured to: determine a task to be performed by the robot, where the task includes a plurality of phases; cause hydraulic fluid having a first pressure level to flow from the source to the hydraulic actuators for the robot to perform a first phase of the plurality of phases of the task; based on a second phase of the task, determine a second pressure level for the hydraulic fluid; and adjust, based on the second pressure level, operation of the hydraulic system before the robot begins the second phase of the task.

摘要： It is challenging to detect end of stroke for hydraulically actuated, reciprocating piston pumps for a variety of reasons. When the pump pressurizes a process fluid to a 10 relatively low pressure the magnitude of hydraulic fluid pressure is not as distinct compared to the magnitude of a pressure drop across a shuttle valve employed to detect end of stroke, which makes detecting the end of stroke event difficult. A method is disclosed for detecting end of a piston stroke in a hydraulic motor comprising a reciprocating piston with a shuttle valve. The method comprises 1 detecting end of piston stroke when a magnitude of a rate of change of hydraulic fluid pressure is substantially greater than a magnitude of a mean rate of change of hydraulic fluid pressure over said piston stroke; and noise in a hydraulic fluid pressure signal is substantially negligible.
摘要翻译：由于各种原因，检测液压致动往复式活塞泵的行程终点是很困难的。当泵将过程流体加压到10个相对较低的压力时，与用于检测中风结束的梭阀相比，液压流体压力的大小与压差的大小相比不显着，这使得检测到中风事件结束难。公开了一种用于检测液压马达中活塞冲程结束的方法，该液压马达包括具有梭阀的往复活塞。该方法包括：当液压流体压力的变化幅度大大大于在所述活塞行程上的液压流体压力的平均变化率的大小时，检测活塞行程的末端; 并且液压流体压力信号中的噪声基本上可以忽略不计。
