摘要

A 4-way valve for selectively connecting two liquid supply lines separately to a container. The valve comprises a housing forming four chambers each provided with an inlet/outlet connection and each connected by means of connecting channels with two adjacent chambers. Each chamber is provided with a rotary slide displaceable between a first operating position in which the slide closes one of said connecting channels of the chamber and a second operating position in which the slide closes the other of said connecting channels of said chamber. The slides are operationally coupled to each other in such a way that in each operating position two connecting channels are closed at two ends and the other two connecting channels are open in order to obtain a double sealing of said closed connecting channels.
