Abstract
The invention relates to a valve (10, 40, 60, 80, 100, 120, 150, 210), comprising a first valve element (12, 42, 62, 82, 102, 122, 152, 212) and a second valve element (14, 44, 64, 84, 104, 124, 154, 214), wherein the first valve element comprises a first carrier part (13, 43, 63, 83, 103, 123, 153, 213) which is made of plastic material and a first surface element (16, 46, 66, 86, 106, 126, 158) which is made of silicon or silicon oxide and is fastened to the first carrier part, and the second valve element comprises a second carrier part (15, 45, 65, 85, 105, 125, 155, 215) made of plastic material and a second surface element (18, 47, 67, 87, 107, 127, 159, 218) which is made of silicon or silicon oxide and is fastened to the second carrier part. The valve elements are arranged such that the first and second surface elements are seated in a planar manner against each other at least partially along an abutment surface, wherein the valve elements can be moved relative to each other in at least one direction parallel to the abutment surface of the surface elements. The first surface element has at least one first opening (20, 20′, 50, 70, 70′, 90, 90′, 110, 130, 130′, 162) and the second surface element has at least one second opening (22, 22′, 52, 52′, 52″, 72, 72′, 92, 92′, 112, 112′, 132, 132′, 163, 222), wherein the valve elements can be moved relative to each other in the at least one direction parallel to the abutment surface in at least one first position, in which the at least one first opening and the at least one second opening are in fluid connection with each other, and at least one second position, in which the at least one first opening and the at least one second opening are not in fluid connection with each other. The invention further relates to a device (200) comprising such a valve, to a use of the valve in a device, and to a micropump (400, 900), a nebulizer system (700) and a dosing/mixing device (500) comprising such a valve.
