摘要： A filter device, particularly for filtering melt-type fluids, such as polymer melts, includes at least one filter disk having two filter disk halves connected to each other by their edges and provided with filter material on their exterior surfaces. The filter disk halves are held apart by a supporting device delimiting a substantially free hollow area between them, through which a fluid can flow freely. Inwardly, they delimit an outflow opening for the melt-type filtered fluid. The supporting device has individual supporting cams of substantially equal outer dimensions and arranged in several groups. Separated from each other, the supporting cams extend radially outwardly form the outflow opening, are rigidly connected to at least one of the two halves, and traverse the hollow area in such a way as to rest against the other filter disk half. This results in a filter device which is economical to produce and which has enhanced filter performance when in operation. It is suited particularly to filtering melt-type liquids, such as polymer melts, under high pressure.
