FILTER DEVICE FOR THE FILTRATION OF FLUIDS

摘要

The filter device (10), provided for the filtration of fluids, comprises two interconnected material structures (14, 16) forming a filter unit (12). The two material structures (14, 16) are mechanically stable, at least one of the two material structures (14, 16) being elastically deformable. The two material structures (14, 16) are connected to each other at opposite connecting sites, with one (16) of the material structures forming an arch between the connecting sites. This arch has been generated by elastic deformation of the respective material structure (16) so that this material structure (16) is mechanically biased. A stretching movement of this material structure (16) is prevented by the connection of this material structure (16) to the other material structure (14) which in turn is of substantially plane configuration and is tensioned. Each thus constructed filter unit (12) offers high stability against the forces generated by the fluid flow so that a filter element (10) comprising such filter units can be inserted without additional constructions or elements which maintain the arched structure of the curved one material structure (16).
