Single handle mixing valve.

摘要

The monoblock faucet comprises a faucet body (1) with its corresponding outlet pipe (2), including inside the body (1) a cartridge that determines the cold water and hot water distributing means , the cartridge being operated by a top external handle (3) provided with tiltable movement to open the faucet and provided with rotary movement between the limit positions that will correspond to the maximum cold water position and the maximum hot water position. The particularity of the faucet is that the handle (3) is mounted in such a way that in the maximum cold water limit position its longitudinal axis corresponds to the longitudinal axis of the pipe, in such a way that opening from said position will prevent the hot water heater from igniting, since it is far away from the position in which the outflow of hot water starts. It has, likewise, been foreseen that the holes of the body of the faucet that communicate with those that the cartridge must have to distribute the cold water, hot water or mixture thereof, in accordance with the positions of the handle and thereof of the cartridge, are tilted and the symmetric axis thereof is out of phase with regard to the symmetric axis of the pipe, an amplitude approximately half that determined between the two limit positions of the operating handle, so that it is also achieved that the maximum cold water position corresponds to the one in which the symmetric axis of the handle coincides with the one of the pipe. The faucet is completed with a flow adjustment device mounted transversely on the pipe, a device which consists of a screw that can be turned from the outside in order to place it in any position between a maximum flow limit and another minimum flow limit.
