Abstract
In a device for delivering and conveying paste-like substances, like sausage stuffing, for the purpose of dosing or the dosed filling into sausage cases, the stuffing located in the pump chamber, based on its compressibility, is pre-compressed in order to reach a uniform substance density required for exact dosing. For the purpose of limitation of the pre-compression pressure occurring in the processing of substances of less compressibility, the bottom part and/or the cover part of the pump casing are provided with a sealing recess which enters the latter and are also supported against springs in a resilient manner.
