Abstract

An improved autonomous well valve (1) having a body (2) that constitutes an actuator for opening and closing of first and second valves (34, 44), the body (2) having an body axis (26) of symmetry, and where the body (2), that in operation is submerged, has an effective density that is equal or greater than the density of a first fluid and less than the density of a second fluid, and where the body (2) is placed in a housing (8), the housing (8) having a housing axis (24) of symmetry, where that at least two first valves (34) that are designed to allow flow between the inside and outside of the housing (8), are distributed about the body axis (26) and mechanically connected be- tween the body (2) and the housing (8), and where the body axis (26) at the first valves (34) is restricted from moving above the housing axis (24).
