US Patent 12023691 Fluid switching valve with pressure difference subjectable valve closure bodies

A fluid switching valve comprising a valve housing, an inlet area, a first outlet and a second outlet out of the valve housing, a first fluid connection, a second fluid connection, a counter pressure chamber, a first valve unit, a second valve unit and a user-operable switching body for switching the valve closure bodies between their closed position and their open position. Here, the counter pressure chamber is fluid-connected through an inlet link duct to the inlet area. The valve units each have a valve closure body, which is movable between a closed position and an open position for the respective fluid connection and is arranged so as to be subjectable to fluid pressure on the one hand via the inlet area and on the other hand via the counter pressure chamber. The switching body is switchable between different operating positions by a switching movement. The counter pressure chamber is fluid-connected through a first blockable outlet link duct to the first outlet, and through a second blockable outlet link duct to the second outlet.
