VALVE APPARATUS FOR CONTROLLING THE FLOW OF FLUIDS IN TWO TEMPERATURE CONTROL CIRCUITS, COMPENSATING TANK APPARATUS WITH SUCH A VALVE APPARATUS, AND A TEMPERATURE CONTROL CIRCUIT APPARATUS WITH SUCH A COMPENSATING TANK APPARATUS

Abstract:

A valve apparatus is provided for controlling the flow of fluids in two temperature control circuits and includes an actuator, a valve housing with a first receiving chamber and a second receiving chamber, a direct ball valve having the first receiving chamber with at least a first and a second fluid port, wherein a first ball device with a first passageway is rotatably mounted in the first receiving chamber, wherein the first ball device is coupled to the actuator and is directly actuatable by the actuator, and an indirect ball valve having the second receiving chamber with at least a third and a fourth fluid port, wherein in the second receiving chamber a second ball device with a second passageway is rotatably mounted, wherein the second ball device is coupled to the first ball device and is thus actuatable by the direct ball valve and indirectly actuatable by the actuator.
