Control cartridge for a single-lever mixer fitting
Реферат: In a plumbing assembly, a control cartridge for a single-lever mixer fitting is small enough to be installed into the mouth region of a discharge arm. The shut-off elements include a first control disk, which is fixed to the fitting housing and a second control disk, which can be rotated by an actuating lever. The control disks preferably consist of ceramic and have, in each case, two through-passages, one each for cold and hot water. Upon rotation of the fitting, first the cold-water through-passage and then hot-water through-passage are released, and, subsequently, the cold-water through-passage is throttled. With exclusively one rotary movement of the lever, the following flow conditions result: cold - mixed - hot. The resulting water through-flow remains at least approximately constant after achieving the maximum cold-water through-flow.
