  • Patent number: 11697115
    Abstract: A dispensing device which has a dispensing channel extending between a supply opening and an output opening into the course of which a pump, a selection valve and a dispensing valve are connected. The selection valve is also connected to a pressurised air source. The dispensing device allows a dispensed output of a fluid, wherein a buffer channel portion is filled by the pump in a pump dispensing phase, to which buffer channel portion pressure is applied from the pressurised air source during a pressurised air dispensing phase such that a precise fluid output is subsequently possible by clocked actuation of the dispensing valve until the target fluid amount has been reached.

  • Patent number: 11660593
    Abstract: Fluid assembly for use in a fluid system, having a control module including a processing unit for processing control commands into individual electrical control signals with individually adjustable control signal levels and a control signal level electrically connected to the processing unit, with a power unit, which has a power module for converting the control signals into individual electrical control currents as a function of the control signal levels and an output interface electrically connected to the power module, wherein the processing unit is designed to provide a first group of control signals in a first time interval which can be individually predetermined for each control signal and to provide a second group of control signals in a second time interval which can be individually predetermined for each control signal and follows the respective first time interval, wherein the first control signal and the second control signal are selected in such a way that the control currents in the first time in
