Internal housing for a sanitary fitting and sanitary fitting

摘要

Abstract The internal housing (12) according to the invention for a sanitary fitting has a receiving opening (14) 5 intended to receive a control cartridge (16). The receiving opening (14) is bounded along its circumference by a wall (20) and at its lower end by a base (22) In order to supply water to the control cartridge (16), the internal housing (12) has an inlet 10 opening (26) passing through the base (22) . A discharge opening (40) for the discharge of the water flowing out from the control cartridge ,(16) also passes through the base (22). In order to ensure a leak-tight transition between the internal housing (12) and the control 15 cartridge (16) , an inlet seal groove (57) open on its upper side and completely surrounding the inlet opening (26), and a discharge seal groove (60) open on its upper side and completely surrounding the discharge opening (40) are formed in the base (22). The inlet 20 seal groove (57) is intended to receive an inlet seal element (54') and the discharge seal groove (60) is intended to receive a discharge seal element (54'') that consequently bear on the one hand against the internal housing (12) and on the other hand against the 25 control cartridge (16).
