    摘要: A system and method for controlling a valve increases the availability of a control valve assembly used in a control process. A pair of positioners are arranged in a high-availability configuration and individually coupled to a controller. A first positioner includes an output coupled to a switch and a second positioner includes an output coupled to the switch. The operating state of the first positioner is monitored and the output of the first or second positioner allowed to pass through the switch to the control valve is dependent upon the operating status of the first positioner.

    摘要: A hydraulic system for utility vehicles, in particular agricultural tractors, with a regulated hydraulic pump (1) is disclosed for prioritised pressure medium supply to internal and external pressure medium consumers (6, 11, 12), which are fed via load sensing spool valves (20, 26), the external pressure medium consumers (11, 12) being supplied with pressure medium via a priority valve (17). In the case of known utility vehicles the lowest priority is assigned to the internal pressure medium consumers. Situations are known however, when operating an air seeder for example, in which it is not expedient with the pressure medium supply to give preference to the internal pressure medium consumers over the external because the power capacity of the hydraulic system is not then exploited to an optimum. Short supply to such implements leads to a negative influencing of the work pattern.
    In order to improve the work quality of an implement driven by an external pressure medium consumer, it is proposed that priority can be selectively assigned to the internal (6) or the external (11, 12) pressure medium consumers.
    It is thus possible for the driver, in order to ensure optimum operation of the utility vehicle in critical situations, to give priority to external pressure medium consumers. In this way during operation of an implement for dispersion of substances, seed for example, over a wide area, better work quality can be attained, as a reduced supply and thus slower function of the internal power lift are accepted for example.

    摘要: The invention relates to a bus module (15) comprising an electric circuit arrangement which evaluates address data and user data from data telegrams transmitted to the data bus (11) and which controls a fluidic valve (16) which is determined by address data and which corresponds to the user data of the data telegram. The aim of the invention is to maintain a low current load of the bus module, in particular during the control of hydraulic valves (16). After the reception of user data in the form of a switching command for a fluidic valve (16) connected to the bus module (15), the electronic circuit arrangement supplies, in a continuous manner, the fluidic valve (16) with a power supply voltage (Uv) which is determined by the address data during the time of interconnection having a predetermined duration. After completion of the interconnection time, the electronic circuit arrangement supplies the power supply voltage (Uv), in pulse width modulated form having a predetermined pulse- duty factor (T%), to the fluidic-valve (16). Only if the bus module (15) has received user data in the form of a disconnection command for the previously connected fluidic valve (16), the electronic circuit arrangement does not provide any more power supply voltage (Uv) to the fluidic-valve (16).

    摘要: A booster pilot valve (10) operable at ultra low power levels is provided. The booster valve (10) includes a movable spool (160) capable of directing a fluid flow (170) to at least two different paths (118, 119). The booster valve (10) may be coupled to a piezotronic three-way valve (40), which controls the movement of the spool (160) by redirecting a main fluid flow (170) along different paths to create a force on the spool (160). The piezotronic valve (40) is capable of actuation at very low power levels such as might be provided by a Profibus PA or other Bus system.
