Patent AT-E401115-T1: [Translated] FILTER SNAPPER

A device for applying an axial compressive force to a fluid contamination detection system comprising a cup joined by a frangible connection to a filter ring, the force being sufficient to break the frangible connection and collapse a portion of the ring into the cup without damaging the ring. The device includes a stop element and a platform and an actuating mechanism for reciprocally moving the platform relative to the stop element. In a first position, the distance between the platform and the stop element is greater than the axial length of the detection system when the cup and the filter ring of the funnel are connected to each other, and in a second position, the distance between the platform and the stop element is less than the axial length of the detection system when the cup and the filter ring of the funnel are connected to each other.
