Abstract: A shower jet outlet nozzle includes a hollow chamber (1), a lateral wall (2) delimiting the hollow chamber transversely to a nozzle longitudinal axis (DL), and a bottom (3) delimiting the hollow chamber in the direction of the nozzle longitudinal axis on an outlet side, which bottom is made of an elastic material and in which a jet outlet opening structure (4S) including one or a plurality of jet outlet openings (4) and having an open initial configuration, wherein the bottom is configured with the jet outlet opening structure thereof, under the effect of a shower fluid operating pressure in the hollow chamber, to deform in an elastically resilient manner and thereby to steadily increase an opening cross-section of the jet outlet opening structure with increasing shower fluid operating pressure within a normal operating pressure range.

Abstract: A sanitary fitting including a water conduit channel. The sanitary fitting illustratively further includes an insertion duct extending into the water conduit channel and including a user-accessible insertion opening, and an insertion plate including at least one sanitary utility element and exhibiting, in a flow-through region in which the plate has flow-through capability from its one plate main side (H1) to its other plate main side (H2), a smaller plate thickness (PD) as compared to its lateral plate dimension (PL), the insertion plate being insertable in a lateral insertion direction (SL) into the insertion duct via the insertion opening and extractable from the insertion duct counter the insertion direction. The insertion duct remains stationary in an operating position, when the insertion plate is inserted or extracted, and the insertion opening remains user-accessible in the stationary operating position of the insertion duct.

Abstract: An apparatus for diagnosis of a communication channel, wherein a communication signal serves for data transmission and is a frequency-modulated signal. The apparatus includes a receiving circuit, which serves for receiving the frequency-modulated signal. The receiving circuit includes a monitoring unit, which serves for determining a signal parameter of the frequency-modulated signal. The receiving circuit also includes a demodulator, which serves to demodulate the frequency-modulated signal. The receiving circuit also includes a signal processing unit, which is connected with the demodulator and with the monitoring unit, wherein the signal processing unit, at least at times, serves for evaluating the signal parameter of the frequency-modulated signal determined by means the monitoring unit and, at least at times, for evaluating the demodulated signal.

Abstract: A shower device according to the invention includes a shower head housing having a jet disk and a multiplicity of jet outlet openings. The jet outlet openings are divided into multiple groups of jet outlet openings. For each group of jet outlet openings, a distinct chamber is formed in the shower head housing. A water inlet can for example be connected by means of a change-over valve to in each case one of the chambers fluidic in parallel. The two chambers are arranged consecutively in the shower head housing. The water exiting the rear chamber as viewed relative to the jet disk can for example pass through the front chamber in a sealed channel or as a jet, which passes through a larger opening of the jet disk.

Abstract: A shower head according to the invention comprises a rotor with a closing plate which bears against a jet disk with jet passage openings and, when the rotor is rotated, alternately opens and closes said jet passage openings. Pulsed massage jets are generated at the outlet of the jet passage openings as a result. A further jet outlet disk with jet out let openings is arranged downstream of said jet disk, with said jet outlet openings being aligned axially opposite the jet passage openings of the jet disk. Ventilation chambers are arranged between the two disks, said ventilation chambers being connected to the outside of the shower head. The pulsed jets are ventilated downstream of the jet passage openings as a result.
