Abstract
A two-component rotary valve for controlling the fluid flow through a fluid conduit, the rotary valve being injection-moulded in two steps with no need for assembly after the injection moulding procedure. The rotary valve comprises a valve house with a plug inside it, and the rotary valve has sealing means in the form of local variations in the radius of the plug and house along their lengths. Thereby, a rotary valve is obtained which does not require a viscous sealant, such as silicone, to eliminate the risk of leakage, when the valve is open.
