Tank valve, in particular for a vehicle fuel tank; the body of that valve consists of two parts fixed to each other with cylindrical inlets connected with atmosphere and with the tank respectively; and inside the body, a moving component is located in the shape of a mushroom loaded by a spring, characterized in that between the parts (1, 2) of the body, a rigid and tight wall (10) is located, which divides the body in two parts; this wall is outfitted with a central aperture (12) and a number of side apertures (18) located on the circle having the same axis as the central aperture (12); besides, the wall includes concentric in relation to the aperture (12) ring-like protrusions (20, 22, 23); two of those protrusions (22, 23) are located on the same side of the wall (10), the protrusion (20) is located on the other side of the wall (10); the mushroom-shaped part (13) is located in the central aperture (12) of the wall (10); on the leg of the mushroom-shaped element (13), a plate (14) is located, and one end of a spring (15) contacts the plate (14), and the other end contacts the plate (16) located on the leg of the mushroom-shaped element (13); the plate (16) is flat from the wall (10) side; whereas the central aperture (12) in the wall (10) and in the plate (16) has bigger diameter than that of the diameter of the leg of the mushroom-shaped element (13); whereas the area of ring [à]<IMAGE>
