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.

Abstract: The invention relates to a peristaltic system (50), which comprises at least two pumps (30, 30?) that can be separately actuated, each pump comprising a pump chamber (14) suited for receiving a fluid, a pump element (16) suited for suctioning and displacing a fluid into and from the pump chamber (14), two check valves (12, 12?), one of which (12) is in fluid connection with an inlet of the pump chamber (14) and the other (12?) is in fluid connection with an outlet of the pump chamber (14), and a valve (18) which is closed in the idle state of the pump (30, 30?) and in fluid connection with the check valves (12, 12?). The peristaltic system (50) further comprises a container (40) suited for receiving a fluid, the container being in fluid connection with an inlet of the one pump (30?) and with an outlet of the other pump (30) and flexibly designed at least in some regions such that the volume of the container depends on the volume of a fluid that is received.

Abstract: The invention relates to a chamber, in particular a pump chamber, comprising a plate-shaped first half (10) and a plate-shaped second half (12). The first and second halves are connected to one another by a closed connecting seam (20) in a surface-to-surface relation, and at least one half has at least one aperture (14) lying within the connecting seam. Furthermore, at least the second half is thermally deformed within the closed connecting seam in such a manner that it is formed to bulge relative to the connecting surface with the first half such that a hollow space (30) is formed between the first and second halves. In a second aspect, the invention relates to a pump having a configuration as described above. In a third aspect, the invention relates to a method for producing a chamber as described above.
