The invention relates to a filter press for filtering suspensions that comprises a plurality of filter plates (1M, 1K) that can be displaced in parallel with respect to one another. In a filtering position, said filter plates can be compressed to a package that comprises a filter chamber (23) between respective two filter plates (1M, 1K), said chamber being provided with at least one filter cloth (7M, 7K). In a discharge position, adjoining filter plates (1M, 1K) can be moved apart by a discharge distance (3) so that the filter cake adhering to the filter cloth (7K) can be discharged. Every filter chamber (3) is correlated with at least one filling element (2) for feeding the suspension to the filter chamber (23). The aim of the invention is to prevent leakages in the zone of the peripheral sealing edge, to guarantee an unimpaired filter capacity during feeding and to facilitate operation of the filter press without an external supply line and outgoing connection lines. To this end, the filling element (2) is disposed on a joining piece (5) that extends outside a plate level and within a sealing edge (27) on the periphery of the filter plates (1M, 1K) and that can be linked with a filter plate (1M). In the filtering position, the filling elements (2) form a suspension supply channel (22) that extends through the filter plate package and are sealingly wedged between adjoining filter plates (1M, 1K).
