Abstract
The water discharge device (faucet) is provided with a pullout spray head (2) that may be pulled down from the curved pipe (3) and which spray head is provided with a discharge mouthpiece (5). A switching valve (8) is arranged within said spray head (2) whereby said switching valve (8) is positioned in a housing (7) that is dimensioned in such a manner that it may be grasped by the user with one hand. Said switching valve (8) may be actuated by an operating lever (6). Said operating lever (6) is a bail (U-shaped lever) that is pivotably mounted on a water-guiding part (24) and which in turn is connected to a switching arrangement (28) mounted in said housing (7) with which a valve member (9) of the diverting valve (28) may be moved in its longitudinal direction during movement of the bail (6). Said bail (6) is arranged in such a manner that it may be operated with the thumb of the hand that is grasping said housing (7). Said valve member (9) may be preferably moved by means of a cam (17) of said switching arrangement (28). The device may be operated ergonomically in a very simple manner.
