Abstract
The invention relates to a valve (1) for mounting to a surface (2) and for use in a flow path, which flows through said surface (2), for permitting flow in said flow path in a first direction and for preventing flow in said flow path in a second direction being opposite to the first direction. The valve (1) comprises: one or more ports (21) defined by a plurality of lips (22), wherein each lip (22) is resiliently deformable from a first position, in which the lips (22) are in contact with one another in order to close the respective port (21), to a second position, in which the respective port (21) is opened in order to permit flow in the first direction, and one or more contacting structures (30) arranged to mechanically contact the surface (2), when the valve is mounted to the surface (2), such that the one or more contacting structures (30) bias the lips (22) into the first position.
