Abstract
A one-way restrictor is provided which is configured like a lip valve and includes a bypass flow channel. The bypass flow channel is formed by an at least one opening which is located between an intake and an outlet and can be covered, at least partially, by the sealing element of the valve. By way of a control member the sealing element can be moved relative to the opening in such a way that the cross-section of the opening covered by the sealing element can be adjusted.
