ABSTRACT A valve for the addition of water to electrochemical accumulator batteries and for maintaining the flow of liquid at a constant level. A membrane (24) in a valve body (12) is biased by means of a spring (26) against a wall (28) arranged concentrically with an inlet orifice (16), said wall creating an inner chamber (30) of circular cross-section and an outer chamber (32), which is of annular cross-section and is connected to an outlet connection (18) via a constricted orifice (20). A spindle (34) at the centre of the membrane passes freely through the inlet orifice and exhibits outside the latter a conically enlarged part (36), the cross-sectional area of which increases in proportion to the distance to the inlet orifice, serving as a valveseat, and which is intended to provide a seal when the spring yields to the membrane.
