A valve for a device for administering a liquid medicine, the valve comprising:
- a valve body which has an inner space for receiving a liquid, wherein the valve body comprises:
- a liquid inlet and
- an opposite liquid outlet, which both open out into the inner space;
- and
- a plurality of microchannels is arranged in the inner space, said plurality of microchannels extending in the connection direction between the liquid inlet and the liquid outlet;
- wherein
- the liquid inlet is configured to feed liquid medicine to two or more microchannels of the plurality of microchannels simultaneously;
- and
- the plurality of microchannels comprise:
- a grid made of parallel, rod-shaped boundary elements or the grid comprises several parallel layers of the parallel, rod-shaped boundary elements that are arranged offset to one another,
- in which, a longitudinal length of the parallel, rod-shaped boundary elements that is perpendicular to the connection direction between the liquid inlet and the liquid outlet and extends from an inner side of a side wall bordering the inner space of the valve body in a direction to an opposite side wall, without reaching this, such that a spacing between the parallel, rod-shaped boundary elements and the respectively opposite side wall is formed.
