DEVICE FOR FILTERING A FLUID, PARTICULARLY A LIQUEFIED PLASTIC

摘要

Disclosed is a device (1) for filtering a fluid, comprising a housing (2), a fluid feed channel (3), a fluid discharge channel (4) and a filter carrier (5) which can be moved between two positions in order to hold at least two plate-type filters (8). The filter carrier is embodied in the form of a pin (5) which can be arranged in a fluid-tight axially displaceable manner in a bore (6) of the housing, wherein the end area (10) of the fluid feed channel (3) facing towards the pin (5) and the beginning area (11) of the fluid discharge channel (4) facing away from the pin (5), when seen in the direction (24) in which the pin (5) is displaced, is expanded and the axial length of the expanded end area (10) of the fluid feed channel (3) and the expanded beginning area (11) of the fluid discharge channel (4) Is such that it corresponds to the sum (X) of the axial length of a single through opening (7) and to the axial length of a single intermediate section (12) of the pin (5) existing between two adjacent through openings (7), wherein the axial length of all intermediate sections (12) is identical.
