WIPO Patent Application WO/2016/142060

A3

The invention relates to a sanitary change-over valve (1) comprising a valve housing (2) which has a valve inlet (3) and two selectively controllable valve outlets (4, 5), a valve piston (6) that can be moved from a first switch-over position, in which the fluid is conducted via a flow path passing through a first valve outlet (4), into a second switch-over position, in which the fluid is conducted via a flow path passing through a second valve outlet (5), as soon as the stretch of the second flow path leading from the change-over valve (1) has been released. The valve piston (6) is designed as a hollow body, through which the fluid is conducted by means of at least one piston inlet (9) positioned on the piston circumference in the course of at least one of the flow paths. The change-over valve according to the invention is characterised in that the fluid conducted by means of the at least one piston inlet (9) is led, in the course of the second flow path, through a first piston outlet provided on the piston end face facing away from the piston head (10), and in that a flow throttle (12), a flow-control valve (11) or a check valve is provided in the first piston outlet.
