Abstract: The invention relates to a valve (1) for a sanitary fitting, at least comprising: a valve unit (2) with a valve housing (3) and with an inflow connection (4) and an outflow connection (5) for transferring the fluid supplied via the inflow connection (4), wherein the inflow connection (4) and the outflow connection (5) are switchably connectable to each other by the valve unit (2), wherein the inflow connection (4) and the outflow connection (5) are fluidically separated from each other in a first position of the valve unit (2) and are connected to each other in a second position; and a pushbutton housing (6) which is connected to the valve housing (3) and has an actuating button (7) for switching the valve unit (2), wherein the actuating button (7) is held in a starting position (8) by a first holding mechanism (9); wherein, starting from the starting position (8), a second holding mechanism (12) of the valve unit (2) can be actuated by shifting of the actuating button (7) by a first distance (11) along
Abstract: A nut (1) for securing a sanitary faucet (2) to a support (3), comprising: a base body (4) with a plurality of threaded lugs (5), which can be adjusted in a radial direction (7) when a nut (1) is pushed onto a thread (6) of the sanitary faucet (2), and a twist lock (8), which can be rotated between a locking position (9) and a release position (10) and which is secured to the base body (4), wherein the twist lock (8) locks the threaded lugs (5) in the locking position (9).
Abstract: A functional unit (1) for a shower toilet (2), having at least the features listed below: at least one shower device (3) for dispensing a liquid; a liquid heater (5) for heating the liquid; and a limescale filter (6) for filtering the liquid. Additionally, a shower toilet (2) having such a functional unit (1).
Abstract: The invention relates to a plumbing fixture (1) for a shower system (2), at least comprising a supply line (3) for supplying at least one liquid towards an outlet (4) of the plumbing fixture (1); a first connection (5) to the supply line (3) for switchably connecting the supply line (3) to a compressed-air line (6); wherein a liquid present in the supply line (3) can be purged through the outlet (4) via the compressed-air line (6).
Abstract: A water faucet having an adjustable cartridge for the infinitely variable mixing of a cold-water flow and a hot-water flow to form a mixed-water flow, having a first adjustability, and having an operating lever, which is connected to the first adjustability via a transmission mechanism such that the mixing ratio of cold water and hot water can be set by a temperature setting motion of the operating lever, the temperature setting motion being a rotary motion about an axis of rotation, the transmission mechanism having a stop, which limits a movement of the first adjustability in the direction of more hot water at a threshold setting, the stop being designed such that the operating lever is brought into an unlocking position by an unlocking motion deviating from the temperature setting motion, such that further movement in the direction of more hot water is made possible beyond the threshold setting.
