Problems solved by technology
However, the switching valve previously known from EP 1 664 957 B1 cannot be adapted to the different requirements of different applications, especially also in the low-pressure range
Furthermore, the previously known switching valves are relatively complex in construction and require a corresponding space requirement

Embodiment Construction
[0046] exist Figures 1 to 26 The sanitary switching valve 1 is shown in different embodiments and application examples. The switchover valve 1 is used here to be inserted into the water pipe in order to allow water to flow selectively from one of the water outlets or from the other water outlet when required. The sanitary switching valve 1 has a valve housing 2 with a valve inlet 3 and two selectively controllable valve outlets 4 , 5 . A valve piston 6 is displaceably guided in the valve housing 2, which valve piston can figure 1 shown in the first transition position and figure 2 movement between the second transition positions shown. in accordance with figure 1 In the switching position of the water is directed through a flow path through the first valve outlet 4, while in accordance with figure 2 In the second switching position of , the section of the second flow path extending from the switching valve 1 via the second valve outlet 5 is opened and for this purpose ...

The invention relates to a sanitary change-over valve comprising a valve housing which has a valve inlet and two selectively controllable valve outlets, a valve piston 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, into a second switch-over position, in which the fluid is conducted via a flow path passing through a second valve outlet, as soon as the stretch of the second flow path leading from the change-over valve has been released. The valve piston is designed as a hollow body, through which the fluid is conducted by means of at least one piston inlet 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 characterized in that the fluid conducted by means of the at least one piston inlet 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, and in that a flow throttle, a flow-control valve or a check valve is provided in the first piston outlet. The invention also relates to an assembly comprising the change-over valve of this type.
Description
technical field [0001] The invention relates to a hygienic switching valve comprising a valve housing with a valve inlet and two selectively controllable valve outlets, said sanitary switching valve comprising a valve piston, the The valve piston is movable from a first switching position in which fluid is directed through a first flow path through the first valve outlet to a second switching position in which fluid is directed through a second As soon as the section of the second flow path of the second valve outlet that continues from the switching valve is opened, the fluid is guided through this second flow path, wherein the valve piston is formed as a hollow body, and the fluid passes through at least one valve arranged on the circumference of the piston. The piston inlet is guided through the hollow body in the course of at least one of the flow paths. [0002] The invention also relates to a sanitary subassembly comprising a switching valve of the type mentioned at the...
