Float-controlled valve array having redundantly acting float bodies

A float-controlled valve array, comprising a valve module with a duct, a valve seat formation penetrated through by the duct, and a valve body formation, where the valve body formation is displaceable relative to the valve seat formation between a closure position in which the duct is closed through physical abutment of the valve body formation against the valve seat formation, and a passage position in which the valve body formation is arranged with a separation from the valve seat formation such that flow through the duct is possible, where the valve array further comprises a first float body with a first buoyancy volume section and a second float body with a second buoyancy volume section, where the first float body is articulated in a swiveling manner at a first joint and where the second float body is articulated in a swiveling manner at a second joint such that in normal operation each float body is moveable along a buoyancy axis parallel to the gravitational direction between a sinking position and a buoyancy position, where the first and the second float body is each coupled in such a way with the valve body formation that the valve body formation is in the closure position when at least one of the float bodies is in the buoyancy position, and is in the passage position when both float bodies are in the sinking position, wherein when regarding the two float bodies in their respective sinking position as a reference state, the respective buoyancy volume sections of the two float bodies are arranged with separation from one another which is orthogonal to the buoyancy axis, where in a body separation region between the two buoyancy volume sections there is located at least one joint.
