Abstract
The invention concerns a vane pump for conveying bulk substances, in particular meat pastes, having a housing (4) with an inlet (6) and an outlet (10) for the bulk substance. Disposed inside the housing (4) is a rotor (14) displaying a rotatably-journaled, central driving element (16) and several moving vanes (20a to j), which are arranged on the central driving element, in its direction of rotation (C), one behind the other and at an angle to the direction of rotation (C), and commonly surrounded by a limiting wall (24) of the housing (4) running about in the direction of movement (C) of the vanes (20a to j), with the limiting wall (24) forming conveying chambers for picking up (accommodating) bulk substances and, with rotation of the driving element (16), being moved in sequence past the inlet (6) and the outlet (10). Control means are provided for the defined approach of the vanes (20a to j) toward the limiting wall ( 24), up to a minimum distance, through means of which is achievable a sufficient degree of sealing without bodily (physical) contact between the vanes (20a to j) and the limiting wall.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
