Abstract: A throttle unit, in particular of a blow moulding device, includes a throttle and a position sensor. The throttle has an actuator and a drive unit including an electric motor for changing a position of the actuator. A throughflow cross section in a throughflow channel of a fluid can be changed by changing the position of the actuator. The drive unit is arranged at a first end of the actuator. The position sensor monitors the position of the actuator directly. The throttle unit makes it possible to set and adjust the throttle automatically in an accurate but nevertheless cost-effective manner.

Abstract: A jet regulator for a fitting for dispensing boiling water is provided. The jet regulator includes a substantially cylindrical housing with an inlet opening and an outlet opening, and a swirl creating portion, arranged in the region of the inlet opening, with a substantially helically extending flow guide for rotationally accelerating a stream of water flowing through, an expansion zone, following the swirl creating portion, in which the rotationally accelerated stream of water can flow under the action of centrifugal force in the region of the housing inner wall, and a guide portion, in which the rotational movement of the stream of water is decelerated and the latter is guided in a longitudinal direction.

Abstract: A solenoid valve has an electromagnet with a coil, an RFID tag for identifying the solenoid valve, and an antenna for unidirectional or bidirectional communication with the RFID tag. The antenna is the coil of the electromagnet. Using the coil of an electromagnet for communication with an RFID tag permits inexpensive quality assurance when using solenoid valves, in particular in blow moulding machines.

Abstract: A filter device for filtering drinking water, having a connection device on which a receiving part for connection of a filter cartridge is pivotably mounted. The receiving part has a wall which is at least sectionally rotationally symmetrical and forms a convex sliding surface at which inflow and return channels for water to be filtered that lead to a filter connection open. The wall bears sealingly against an inner wall, curved coaxially therewith, of the connection device, and connection openings for an inflow and return of the water to be filtered open out at the inner wall. The receiving part is pivotable into a working position, in which mouths of the inflow and return channels lie sealingly over the connection openings, and into a changeover position, in which the filter cartridge can be removed from and/or inserted into the receiving part, and the wall of the receiving part sealingly closes off the connection openings for the inflow and outflow of the water to be filtered.

Abstract: In a connection device for coupling a gas pressure container provided with a connection coupling there is provided a guide device which is pivotable about a pivot axis between first and second pivoted positions, wherein the guide device includes an opening for inserting the gas pressure container in an insertion direction extending radially with respect to the pivot axis. A plug nipple is rigidly arranged on the connection device and projects into an inner region of the guide device such that the longitudinal axis of the nipple extends radially relative to the pivot axis and is situated parallel to the insertion direction in the first pivoted position of the guide device. The gas pressure container possesses a connection coupling with a rotationally symmetrical valve body having a coupling opening for receiving the plug nipple.

Abstract: A method for adapting a control menu of an extraction unit (10) for drinking water (11) to a network (12), having the steps of: connecting a new device (14), wherein the extraction unit is connected to one or more devices using communication technology to form a network (12), in particular in the form of a bus system; transmitting a physical address of the new device (14) into the network (12) to the extraction unit (10); creating a new device register with the physical address of the new device (14) in the controller of the extraction unit (10); and automatically adapting the control menu of the extraction unit (10) to the new device register, with the result that the new device (14) can be controlled via the extraction unit (10). An extraction unit for carrying out such method is also provided.
