ABSTRACT:
The present invention solves the problem of clogging in the case of an apparatus for conducting a pasty mass, preferably sausage meat, under feed pressure through a tube, which carries said mass and the interior of which communicates via an annular groove and an annular gap with an external supply means for a lubricant which is to be forced under high pressure between the inner wall of the tube and the surface of the pasty mass, said problem being solved in such a way that an inner annular recess of the tube has arranged therein a sleeve-shaped sliding piston, the end face of which is acted upon by the lubricant in an annular groove, said sliding piston being adapted to be axially displaced within said inner annular recess against the force of a pretensioned spring in such a way that, in the case of low lubricant pressure, it closes the annular gap by means of an annular shoulder provided on the end face and protruding axially beyond the the annular groove in said end face and that, in the case of high lubricant pressure, it opens said annular gap so that no sausage meat can penetrate into the annular gap in the case of pressure fluctuations in the lubricant.
