A fixture apparatus having a combined shut-off valve and check valve comprising a valve body (6) slidably disposed on a regulating stem (2) provided with a regulating means (3) for engagement with a valve seat (5) in the fixture housing (1), and a mixing valve (9, 17), to be coupled into a cold water inlet pipe and hot water outlet pipe to a hot heater of the compressor type. The fixture housing (1) has two passages with inlet and outlet openings for, respectively, cold water and hot water, and a transverse passage (20) therebetween with the outlet opening (12) for cold water to the hot water heater therein, said transverse passage (20) also constituting a section of the cold water passage. The valve seat (5) for the combined valves is formed by a narrowed area provided in the transverse passage (20) between the cold water inlet (4) and the cold water outlet opening (12). The valve body (6) is resting in spring loaded contact against the valve seat (5). The interior end (2c) of the stem (2) is provided with a carrier (10) for the valve body (6). A valve body (10a) is disposed on the stem (2) outside of the carrier (10) to engage with a valve seat (18a) on a narrowed area (18b) in the transverse passage (20) between said cold water outlet opening (12) and the mixed water outlet opening (19). Manual regulation and optional closing of the flow of cold water and thereby regulating of the hot water temperature are obtained. |
