The fixture housing (10) has a fixed housing part (16a) which is surrounded by a shell element (18) pivotable about the axis (17). A connection piece (58), in which a guide bush (66) is inserted, projects forwardly from the shell element (18). The guide bush (66) defines, together with the inner wall (58'') of the connection piece (58), the shell space (78), which is connected to the atmosphere by means of the passage (90). In addition, the shell space (78) is flow-connected by means of the ventilation passage (92) to the annular duct (94) which is flow-connected by means of the ventilation conduit (100) to the ventilation opening (102) of the safety device (46). The water supplied through the feed pipe (44) is mixed in the control cartridge (42) and flows through the safety device (46) arranged downstream thereof and the pipe (52) into the hose (54) to the spray head (60). In conditions permitting a backflow of water into the feed pipe (44), the safety device (46) prevents this backflow and ventilates the pipe (52) and the hose (54) by freeing the ventilation opening (102). Any water escaping through the ventilation opening (102) during this process is conveyed through the ventilation duct (104) into the depression (130) of the sink (26). …<IMAGE>… |
