Abstract

The unidirectional flow restrictor comprises a first channel (102) between a fluid pipe (100) and throttle member (103) and a second channel (104) between the throttle member and an appliance (101), connected by a third channel (105) with a non-return valve (113). The second channel consists of an axial bore of larger cross-section than the throttle cross-section. The first channel includes a radial opening (102b) leading into the second channel in the region of the throttle member. The third channel leads into the second between the throttle member and the appliance. The non-return valve consists of a deformable ring concentric to first or second channel.
