Abstract: The lever valve for fixing in or at a body of the sanitary fixture, comprises an adjusting lever (3), sleeve (2) arranged in a valve housing, a resilient locking element (6) and retaining lug (7) intended at the adjusting lever. The adjusting lever is led out of the valve housing and is held at a swivel axle by the sleeve arranged in the valve housing. A control variable for a valve member is determined by a pivotal motion of the adjusting lever in a swiveling path of the sleeve. The resilient locking element acts radially to the swivel axis. The lever valve for fixing in or at a body of the sanitary fixture, comprises an adjusting lever (3), sleeve (2) arranged in a valve housing, a resilient locking element (6) and retaining lug (7) intended at the adjusting lever. The adjusting lever is led out of the valve housing and is held at a swivel axle by the sleeve arranged in the valve housing. A control variable for a valve member is determined by a pivotal motion of the adjusting lever in a swiveling path of the sleeve. The resilient locking element acts radially to the swivel axis and is intended as a limiting stop element during swiveling motion of the adjusting lever. A recess (22) extends over half of the length of the swiveling path, also extends from the exterior frontal side of the sleeve up to a region close to the swiveling axis, and is formed in the two sidewalls of the swiveling path. In each recess, the locking element is arranged with a retaining cam lobe, which cooperates with the retaining lug. The locking element is pressed against the retaining lug by a helical spring, which supports itself at the bottom of the recess in the proximity of the swivel axis. The helical spring is held by a blind hole in the locking element. The cross section of the locking element is formed approximately as a circular section. The chord of the circular section forms a part of a sidewall in the swiveling path. At the side lying opposite to the sidewall, a cylindrical convexity is intended within the helical spring region and an appropriate cylindrical concavity is intended in the recess. The locking element exhibits a lateral guidance surface, which exhibits a length that corresponds to 0.6-0.9 times the length of the recess from the frontal surface of the sleeve up to the bottom of the recess. A niche for the admission and support of the helical spring, is formed in the bottom of the recess. A lateral supporting surface is formed in the recess. The locking element is supported by a contact surface at the supporting surface. A notch is arranged besides a retaining lug, concentric to the swivel axis and is formed on the locking element, into which a tooth-like structure joins a ratchet. The notch extends itself along a part of the swiveling region of the adjusting lever. The retaining lug is arranged perpendicular to the center axis of the adjusting lever and is arranged at a bar, which is formed at a ring element or at an electrical insulation sleeve. The locking element and/or the ring element is manufactured with the bars from plastic in the injection molding process.
