摘要： A spray nozzle, especially for spraying water in fire prevention systems, has a housing in which there is a vortex chamber into which a first channel into which a first channel for supplying water opens essentially tangentially at a distance from the axis of the vortex and which has a first outlet orifice coaxial with the axis of the vortex. The spray nozzle also has a second outlet orifice arranged inside the vortex chamber so it is coaxial with the first outlet orifice and is located at the end of a second channel that is coaxial with the axis of the vortex. The second channel has an enlarged area upstream from the second outlet orifice, where the cross-sectional area at right angles to the axis of the channel increases in the direction of flow. furthermore, the cross-sectional area of the second channel at right angles to the axis of the channel does not decrease further downstream from the enlargement as seen in the direction of flow. The second outlet orifice is positioned so close to and upstream from the first outlet orifice that a low pressure zone is formed in the enlarged area, distributing the flowing water to form a spray cone that comes out of the second outlet orifice and spreads out inside a spray cone coming out of the first outlet orifice. This yields a uniform fire extinguishing effect and the width of the spray created by the spray nozzle is increased. The spray nozzle according to this invention is simple and inexpensive to manufacture.

摘要： The invention relates to a method for the determination of the electrical work in systems in which the voltage is switched. At preset times for this purpose current values are measured and interpolated between the measurement. With the help of the switched voltage a classification of each interpolated current path is performed. The interpolated current value is then multiplied or integrated by the voltage value/values between the preset times respectively for the determination of the work. Along with the electrical work moreover in accordance with a further method similarly the electrical power in such systems can be determined.

摘要： A method for regulating a charging state of an energy accumulator for a vehicle with a hybrid drive includes detecting a driving speed variable value of the vehicle and determining a nominal charging state of the energy accumulator as a function of the driving speed variable value by a control unit, detecting an actual charging state of the energy accumulator, comparing the actual charging state with the nominal charging state by the control unit, switching on an energy consumer by a charging state regulator, for at least partially discharging the energy accumulator when the actual charging state exceeds the nominal charging state, tabulating a first nominal charging state value as a function of the driving speed variable value by a characteristic curve, in order to determine the nominal charging state of the energy accumulator, and adapting the characteristic curve by the control unit when the vehicle is braked.
