    摘要: According to one aspect of the invention, a hydraulic system includes a controller connected to an operator interface, a pump operable in a first direction for supplying pressurized fluid, and a load-holding valve connected between the pump and a port for connection to an actuator. The load-holding valve may be controlled by the controller and operative in a first position to allow flow to the actuator to operate the actuator against a load and operative in a second position to block load-induced return flow from the actuator to the pump. The controller may be configured to receive a requested actuator stop, to control the first valve to move to the second position in response to the requested actuator stop, to monitor a first system condition in response to the requested actuator stop, to evaluate the monitored system condition with a prescribed criteria, and to determine whether or not to initiate a back-up control routine based on the evaluation.

    摘要: The position controller for a pneumatic field device comprises a current-pressure transducer system having at least two I/P-transducers creating separate pneumatic control signals. Microelectronics creates at least two electrical control signals for the I/P-transducers. A pneumatic signal switching valve has at least two pneumatic inputs for the at least two pneumatic control signals, a pneumatic output for transferring a pneumatic control signal to a working chamber of the pneumatic field device and an electrical switch signal input. The pneumatic signal switch valve comprises a first switch position which blocks a first of the at least two pneumatic control signals and a second switch position which blocks a second of the pneumatic control signals.

    摘要: A hydraulic valve arrangement, in particular a control valve arrangement, of a hydraulic machine, in particular a hydraulic pump, includes at least one valve with a valve body penetrated by a pressure medium passage. The pressure medium passage has a minimum cross section that gives rise, in normal operation, to a control pressure downstream of the minimum cross section in accordance with a pressure acting at a pressure port of the valve. The minimum cross section is arranged close to a pressure medium passage mouth which is arranged upstream or is configured to be subjected to the high pressure. A hydraulic machine arrangement, in particular a pump arrangement, includes the hydraulic valve arrangement.

    摘要: A control device for controlling a hydraulic consumer, is equipped with a distributing valve having a control pressure chamber and a control slide that can be displaced against the force of a spring by the build-up of a control pressure in the control pressure chamber. A pilot control valve controls the supply and discharge of control fluid into and out of the control pressure chamber. A release device is used to drive the control fluid out of the control pressure chamber, bypassing the pilot control valve.
