摘要： The invention relates to a controlled three-way proportional valve unit comprising: a valve assembly with two individual valves; an actuating device actuating valves of the valve assembly; and a control unit acting upon the actuating device and having a control signal input, the valves of the valve assembly being designed as poppet valves arranged on opposite sides and having counter-rotatable valve spindles. The valve spindles are prestressed relative each other in opposite directions by a prestressing element such that, when the actuating unit is inactive, a first poppet valve is open and the second poppet valve is closed. The actuating device comprises an actuator common to both poppet valves, acts upon the two valve spindles and changes the position of the valve spindles counter to the effect of the prestressing element.

摘要： A proportional valve is provided having a pilot control valve that can be controlled by means of a control signal and having a booster valve that can be actuated by means of the pilot control valve. The proportional valve has a compressed-air connection for connecting a compressed-air supply, a working connection, and an air-removal connection. The booster valve has three valve elements, which are arranged one after the other and can each be moved in an axial direction against a spring force.

摘要： The invention relates to a fluidic actuator comprising a drive element (2) that can be supplied with a pressure fluid and a two-stage proportional position controller (3) controlling the supply with pressure fluid to the drive element, said actuator comprising an electro-fluidic pilot stage (10) of the position controller, exactly one electromechanical transducer (14) and exactly one proportional valve (16) actuated by said transducer and having a pressure fluid inlet (18), a control pressure outlet (19) and a discharge outlet (20). A fluidic power stage (11) of the position controller comprises two poppet valves (24, 25) having associated pressure-to-distance converters that are supplied by a common control chamber (34) which is connected to the control pressure outlet (19) of the pre-stage (10).

摘要： A drive unit is provided, particularly a drive unit for operating flow-control valves, comprising a housing, an electrical input, an electromechanical converter assembly, a mechanical output, and an electronic controller. The controller comprises an input unit having at least one pushbutton, which penetrates the housing and can be depressed against the action of a restoring device, and comprises a contactless switch that is actuated by the at least one pushbutton. A mechanical stop independent of the switch itself is associated with the position of the pushbutton that actuates the switch.
