Abstract: An electrohydraulic system having an adjustment device for a valve includes a drive apparatus, a control apparatus, and a preloading apparatus. In the event of a fault, the energy stored in the preloading apparatus can be transferred to the control apparatus such that a rotational motion of the control apparatus begins, which leads to the adjustment of the valve. The preloading apparatus comprises at least one elastic element, which is arranged adjacent to a control shaft of the control apparatus, is stationarily connected to the control shaft, and applies a torque to the control shaft.

Abstract: A filter adaptor joins a canister filter to a hydraulic manifold block. The adaptor includes a hexagonal tool-receiving portion, an outflow passageway and one or more inflow passageways. The outlet flow passageway extends between opposed ends of the adaptor, and is used to direct filtered fluid from the filter to the manifold block. The inlet flow passageway(s) extend between the one end and a sealed region of the adaptor, and are used to direct fluid from the manifold block to the filter. The adaptor includes auxiliary ports formed in the tool-receiving portion that communicate with the inlet flow passageways and permit monitoring thereof.

Abstract: A hydraulic circuit includes a prime mover that is configured to generate an oscillating flow of hydraulic fluid, and an actuator that is driven by the prime mover and configured to provide oscillating motion and to be connected to a load in each direction of the motion. The hydraulic circuit also includes a reclamation device that is disposed in the hydraulic circuit between the prime mover and the actuator. The reclamation device captures and stores a portion of hydraulic fluid displaced from the actuator during a transition between opposed motions, where the portion of hydraulic fluid corresponds to an amount of hydraulic fluid equal to a volume of fluid required to compensate for compression of fluid within the hydraulic circuit due to system pressure and load pressure. The stored fluid is used by the circuit in a subsequent motion.

Abstract: A physical effect (optical effect), which may be observed in solar irradiance as shading due to a cloud passing overhead may be approaching a given location (e.g., a location at or proximate a solar power generator), has been discovered. This optical effect takes place prior to an occurrence of a solar obscuration event by the cloud, and thus this optical effect may be effectively sensed and processed in apparatuses, systems and methods to predict the occurrence of a solar obscuration of the power generator.
