A dirt filter for thermoplastic media has a barrier member within a filter chamber which, in case of an axially symmetrical arrangement with respect to the flow axis, has the basic shape of a double cone. The barrier member defines a barrier gap for the flowing media within the filter chamber. The barrier gap can be widened to a cleaning gap as a result of a displacement of the barrier member. An adjusting member, can be provided which includes an adjusting element, which is mounted in a reception member so as to rotate around its longitudinal axis. The rear end of the adjusting member can be constructed with hexagon wrench faces, which are accessible from the outside of the housing.

A dirt filter for semifluid thermoplastic media comprising a housing for a filter chamber hollowed out from said housing; means for opening the housing; a flow axis; a barrier member disposed in the filter chamber, which barrier member is adjustable in its position by sliding along the flow axis from a filtering position to a cleaning position and vice versa; a feed line inlet hollowed out from the housing, which issues into the filter chamber; a discharge line hollowed out from the housing, which is led out of the housing on a side which is opposite to a side of the barrier member, having the feed line inlet; an annular slot disposed between a surrounding area of the barrier member disposed coaxially to the flow axis and to an oppositely disposed inner wall of the filter chamber, the annular slot being part of the flow connection between feed line inlet and discharge line; in the filtering position of the barrier member the annular slot is a blocking slot, which is narrower than the diameter of the dirt particles to be retained so such particles cannot pass through; when the barrier member is in the cleaning position clearance between the barrier member and chamber wall is greater than the diameter of the dirt particles retained by the blocking slot so the particles can pass through; an adjustment member accessible from the outside for adjusting the position of the blocking member from its filtering position into the cleaning position and vice versa; a guide body adjoining the end of the blocking body on the side disposed toward the feed line inlet; a bead provided at the guide body and protruding outwardly in a radial direction relative to the flow axis and matching a guide recess of the housing when the barrier member is displaced in the direction of the flow axis and where the adjustment member is coupled in a force transmitting way at the circumference of the bead; channels distributed along the circumference of the bead of the guide body for flow through of semifluid thermoplastic media, where the passage width of the channels is larger than the passage width of the blocking slot.
