A diverter valve includes a fixed body (11) with a central inlet connection (12) and several outlet ducts (17) circumferentially spaced about the inlet connection. A rotatable valve member (21) has a center inlet duct (25) in fluid connection with a radially spaced outlet (27) that can be rotatably moved to be aligned with a selected outlet ducts (17) or misaligned to be in a shut off position. The inlet connection (12) and outlet (27) house sealing elements that provide sealing against leakage for the respective ducts.

1. A valve device being operably interposable between a flow control device and at least one fluid delivery unit that can be supplied under the control of said device, said valve device characterized by:a fixed body with an inner facing surface that has an inlet connection and at least one outlet connection radially spaced from said inlet connection; a rotatable valve member having a respective facing surface that is rotatable about a common axis with the inlet connection to selectively open and close fluid connection between said inlet connection of the fixed body and one of the at least one outlet connection of said rotatable member; one of the fixed body and rotatable valve member houses a first sealing member sealingly biased against said facing surface of the other of said fixed body and rotatable valve member, said rotatable member having an internal conveyance duct that has an inlet opening on its surface co-aligned with the inlet connection in said fixed body and said axis of rotation and having an outlet radially spaced the same distance from said inlet of said rotatable member as said at least one outlet in said fixed member is spaced from said respective inlet connection; one of and said at least one outlet in said fixed body and said outlet in said rotatable member contains a respective second sealing member biased against a surface of the other of said rotatable member and fixed body; further characterized by the respective second sealing member in one of the rotatable valve members or fixed body when completely misaligned from any of the outlets in the other of the rotatable members or fixed body and sealingly closes said duct from said outlet in said fixed body to form a stop valve; an outer O-ring sealing ring about said second spring biased sealing member to prevent cross flow as the second spring biased sealing member crosses over an outlet during rotatable operation of said rotatable valve member; said fixed body having a least two outlets at its inner facing surface both being equally spaced from said inlet in said fixed body; said respective sealing member positioned at the outlet end of said duct and biased to abut the inner facing surface of said fixed body; said first sealing member seated in said fixed body and sealingly biased against said surface of said rotatable member about said inlet opening; and said sealing members are made from elastomeric material and are biased by a respective spring.
