Abstract
Abstract A valve for a water faucet or the like of the type which when actuated does not have a part that rises, and which valve includes a rotary sealing plate against which spring-loaded seals cooperate to seal the valve when the plate is turned to the ''''off'''' position. The valve includes a cartridge which has a stem formed as one piece along with the rotary valve and which also has a sleeve in which the stem rotates, the sleeve also being formed as one piece and providing a seat for the spring-loaded inlet seals.
