Flow restrictor with safety feature
First Claim
1. A flow restrictor (101) comprising:
- a flow channel (130) formed between at least a first member (110) and a second member (120) arranged in engagement with each other, the flow channel having an inlet end portion (131) in fluid communication with an inlet (112) opening and an outlet end portion (132) in fluid communication with an outlet opening (113), the flow channel comprising a generally U-formed portion (135) with a pair of opposed first and second channel portions (136, 137), and a safety channel (140) arranged between the opposed first and second channel portions, the safety channel comprising an end portion (142) in fluid communication with an exterior space relative to the flow restrictor.

Abstract
The present invention relates to flow restrictors suitable for the controlled transfer of fluid from a first compartment to a second compartment. More specifically, the invention relates to a safety arrangement reducing the risks associated with diminished flow resistance through the flow restrictor. In a first aspect the present invention provides a flow restrictor comprising a flow-restricting channel formed between at least a first member and a second member arranged in contact with each other, the flow channel being arranged to form at least one generally U-formed portion with a pair of opposed first and second channel portions, and with a safety channel arranged between the opposed first and second channel portions. The safety channel provides a fluid communication with an exterior space relative to the flow restrictor.
