ABSTRACT:
A vane pump for conveying pasty masses, in particular sausage meat, comprising a pump housing and a rotor, which is eccentrically arranged within the pump housing and which is caused to rotate. Radially continuous vanes are supported on the rotor in a radially displaceable manner that define angular conveying cells with the wall of the pump housing and cooperate with the wall to produce a sealing effect. An adjustable pressure piece is mounted in a radial recess in the wall of the pump housing, the pressure piece replacing the contour of the wall of the pump housing with its surface which faces the vanes. Adjustment of the pressure piece adjusts the pressure applied to the vanes in a radial direction in the pressure area of the pump prior to its outlet.
