The device has a container, a nozzle arrangement, a conveyor device, a high-voltage source, a processor for processing measurement values, data and/or reference values, a storage device and a transmitting and receiving unit for transmitting the measurement values, data and/or reference values to an external data processing device and/or for receiving further measurement values, data and/or reference values from the external data processing device.

Abstract: The invention relates to a method and to a delivery apparatus for carrying out the method, wherein the delivery apparatus comprises an eccentric screw pump having a rotor-stator unit with an outlet, a drive unit, a control device and a delivery section, and wherein the delivery apparatus comprises at least one pressure sensor and a characteristic-variable detection device.

Abstract: An operating method for a conveying device with an eccentric screw pump for conveying viscous construction materials comprising sensing a pressure of the construction material at an outlet of the eccentric screw pump when the eccentric screw pump is running and automatically switching off the eccentric screw pump if the pressure exceeds an upper limit value, otherwise continued operation of the eccentric screw pump. The method includes sensing a characteristic variable of the running eccentric screw pump and comparison of the characteristic variable with a first comparison variable, which is characteristic of operation with an open dispensing device and/or with a second comparison variable, which is characteristic of operation with a closed dispensing device, and switching off the eccentric screw pump if operation with a closed dispensing device is detected, otherwise continued operation of the eccentric screw pump.

Abstract: The invention relates to an electrostatic atomizer for liquids, in particular, cosmetics, the atomizer comprising a housing, an electrical energy source, an activation mechanism, control electronics, a high-voltage source, a liquid tank, a delivery device and atomizer nozzles. The delivery device is arranged here between the liquid tank and the atomizer nozzles, the delivery device being connected to the liquid tank by a first line and the delivery device being connected to the atomizer nozzles by a second line, so that the delivery device sucks liquid out of the liquid tank and delivers it to the atomizer nozzles.

Abstract: A method for operating a hand-held spray device, wherein in a first step a target orientation of the spray nozzle relative to the operator control unit is defined, and wherein during operation a rotation of the spray device, brought about by manual movement of the spray, through a z swinging angle, about a z axis which is orthogonal with respect to the longitudinal axis and/or through a y swinging angle about a y axis which is orthogonal with respect to the longitudinal axis and orthogonal with respect to the z axis, by a single sensor and wherein the z swinging angle and/or the y swinging angle engage as interference variables in a closed-loop control circuit and make available closed-loop control variables in such a way that the spray nozzle retains its target orientation by means of closed-loop control of the swinging mechanism.

Abstract: A paint spraying unit for generating a shaped paint jet, including a paint nozzle positioned in a gap, wherein the paint nozzle includes a needle with a needle head that deviates from a rotationally symmetrical cross sectional design and a paint outlet opening that deviates from a rotationally symmetrical cross sectional design. The needle head is displaceable in relation to the paint outlet opening along a longitudinal axis of the needle for controlling a needle valve formed by the paint outlet opening and the needle head. The needle head, with the paint nozzle in a closed position with reference to the longitudinal axis, closes the paint outlet opening in a positive locking manner. In this connection, the needle head and/or the paint outlet opening is/are formed by a material with elastic properties at least in a surface region with which the two components come in contact.

Abstract: A liquid tank for an electrostatic atomizer for liquids is provided, including a receiving space for a liquid and a delimiting wall delimiting the receiving space with respect to the surrounding area. The liquid tank further includes a self-closing valve connecting the liquid tank to the atomizer.

Abstract: The invention relates to a method for controlling an electrostatic atomizer for liquids, the atomizer comprising a liquid tank and a delivery device for liquid from the liquid tank, a high-voltage source and also at least one atomizer nozzle for the atomization of liquid, the at least one atomizer nozzle being connected to the high-voltage source. Here, the voltage and/or the current intensity at at least one of the atomizer nozzles are detected by sensors of control electronics and/or the voltage and/or the current intensity at the high-voltage source are detected by sensors of the control electronics.
