Abstract
A mechanical filter includes a pouch with a double-walled envelope housing a shock-absorbing material in the form of a gel displaceable under pressure. The envelope, of selected geometry, is mainly formed of a thin film of synthetic thermoplastic material, whose physical properties are selected to prevent breakage during displacement of the gel.
