    摘要： The invention relates to a threaded spindle machine comprising: a metal middle housing part (12) arranged between housing end caps (24) and forming a fluid chamber (16) for receiving a plurality of threaded spindles mounted in the housing end caps (24); an insert (18) adhered into the middle housing part, which forms a wear-resistant running surface for the threaded spindles on the inner wall of the fluid chamber (16) and defines an adhesive gap (20) with the inner surface of the middle housing part (12); and at least one filling channel (26) leading from an outer surface of the middle housing part (12) to the adhesive gap (20), characterised in that the filling channel (26) extends from an end of the middle housing part (12), which is adjacent to a housing end cap (24).

    摘要： The invention relates to a sealing arrangement on a pump shaft, comprising: a restrictor section (18) which is arranged along the shaft (16) and divides a high-pressure chamber (12) of the pump from a sealing chamber (20); a seal (22) arranged on the shaft (16) and between the sealing chamber (20) and a low-pressure chamber (30); a restrictor leakage line (34) leading from the sealing chamber (20) to the exterior; and a seal leakage line (42) leading from the low-pressure chamber (30) to the exterior. The sealing arrangement is characterised in that a section of the seal leakage line (42) runs through the interior of the restrictor leakage line (34).
