Abstract: A suction nozzle assembly, comprising a tube coupled to a pressure sink at a distal side thereof, a nozzle, a resilient element which couples said nozzle to a proximal side of said tube and a deformable housing which bridges a gap between said proximal side of said tube and said nozzle. Optionally, a pressure equalizer, for example, a through aperture, is formed in said nozzle.

Abstract: A filtering member is provided including a frame defining a fluid path between an outer face of the frame and an inner face thereof, the fluid path includes a first and a second protruding portions extending between the outer face and the inner face defining a filtering volume therebetween, at least one of the first and a second protruding portions is tapered such that a cross section of the filtering volume increases towards the inlet face; a filtering media disposed in the filtering volume and configured such that when fluid flows from the outer face towards the inner face density of the filtering media is higher than density thereof when fluid flows from the inner face towards the outer face.
