CA 2728425

A filter assembly comprises a filter housing (23) into which a filter element is insertable. A core element (38) is provided extending within the housing (23). The filter assembly comprises a coupling assembly (200) that is insertable into the housing (23), the coupling assembly (200) comprising a leaf spring (201) having a span larger than an internal diameter of the filter housing (23), such that when the leaf spring (201) is inserted into the filter housing (23) the outer edge of the leaf spring (201) engages an inner surface of the filter housing (23) and the leaf spring (201) bulges in the direction of insertion of the leaf spring into the housing, preventing removal of the leaf spring, in a direction opposite to the insertion direction, from the filter housing (23), the coupling assembly (200) comprising a connecting part for connecting the core element (38) to the coupling assembly (200).

Linvention concerne un ensemble de filtre qui comporte un boîtier de filtre (23) dans lequel un élément de filtre peut être inséré. Un élément central (38) sétend à lintérieur du boîtier (23). Lensemble de filtre comprend un ensemble de couplage (200) qui peut être inséré dans le boîtier (23), lensemble de couplage (200) comportant un ressort à lame (201) qui a un pas plus grand que le diamètre interne du boîtier de filtre (23) de sorte que lorsque le ressort à lame (201) est inséré dans le boîtier de filtre (23) le bord externe du ressort à lame (201) engage une surface interne du boîtier de filtre (23) et le ressort à lame (201) se bombe dans la direction de linsertion du ressort à lame dans le boîtier, ce qui empêche la sortie du ressort à lame, dans une direction opposée à la direction dinsertion, du boîtier de filtre (23), lensemble de couplage (200) comportant un élément de raccordement destiné à raccorder lélément central (38) à lensemble de couplage (200).
