Valve, in particular for a component in microfluid technology

摘要

The invention relates to a valve, in particular for a component in microfluid technology, comprising valve bodies (1, 2) which have surfaces (6, 7) intended for contact with each other and which can be moved relative to each other by displacing the contact surfaces (6, 7), wherein channels (4, 5) for the inflow and outflow of a fluid open into one (6) of the contact surfaces (6, 7) and a depression (9) for forming a connection between the channels (4, 5) is provided in the other contact surface (7). According to the invention, a flexible separating film (10), which can be stretched into the depression (9) to form the connection, is arranged between the contact surface (6, 7).

主权项

1. A valve for a structural element of microfluid technology, comprising: valve bodies having matching surfaces for mutual contact while displacing the contact surfaces parallel to each other, wherein ducts for inflow and outflow of a fluid end in one of the contact surfaces and an indentation for formation of a connection between the ducts is provided in the other of the contact surfaces, which other contact surface borders the indentation all around; and a flexible separating film arranged between the contact surfaces and sealing openings of the ducts in a closed valve position, wherein the connection is formed by aligning ends of the ducts with the indentation and expanding the flexible film into the indentation, thereby forming a flow cross section, and wherein the connection is sealed by pressing the flexible film between the contact surfaces all around the indentation.
