Baukastensystem zum Aufbau von Filterelementen unterschiedlicher Baugrößen

摘要

The invention relates to a modular system for putting together different sized filter elements, especially filter elements having different lengths, more particularly filter devices for hydraulic fluids, comprising a support tube (11, 13) that defines an inner cavity in the corresponding filter element, said tube being surrounded by a filter mat that is substantially cylindrical and that matches the different dimensions and having passages to let the fluid pass through. The filter elements also comprise at least one coupling member (5) enabling connection on the end side of a corresponding support tube to an additional support tube having a location (7) on the end side for interacting with and locking on the coupling member (5). Each coupling member (5) is embodied as an attachment plug element with a crown consisting of interspaced tabs (27) extending in axial direction and hooks (29) for snapping on the location (7) of the attached support tube.
