Abstract: Valve comprising a body (2), a centred butterfly (1), mounted with the ability to rotate inside the body (2) from an open position revealing the passage to a closed position covering said passage, and a seal (3) arranged inside a housing which is delimited by the seat and by a face, opposite the seat in the closed position, of the butterfly, the seat and the face converging towards the inside in the axial direction. The seal (3) moves freely in the housing.

Abstract: In this pump, the angle between the imaginary tangent plane to the lip and passing through the axis and an imaginary straight line, perpendicular to the axis and passing through the point furthest from the axis of intersection of the upper surface of a finger with the lateral leading surface of this finger, is between 110 and 140°.
