Abstract
Abstract A hydraulically operating sausage-filling-and turn-off-machine, which comprises a rotating feeding pump adapted to feed filling material. A hydraulic motor with a settable feeding duration drives intermittently the feeding pump for portioning of the filling material. A rotation servo-valve controls the hydraulic motor. An electric control motor is provided, and a portioning drive is driven by the electric control motor and coupled with said rotation servo-valve, whereby the feeding duration of said feeding pump and the portioning size, respectively, is determined by a settable drive value.

Claim 1
Independent Claim
79 words
Hydraulically operating sausage-filling-and turn-off machine, comprising a rotating feeding pump adapted to feed filling material, a hydraulic motor with settable feeding duration driving intermittently said feeding pump for portioning of said filling material, a rotation servo-valve controlling said hydraulic motor, an electric control motor, and a portioning drive driven by said electric control motor and coupled with said rotation servo-valve, whereby the feeding duration of said feeding pump and the portioning, respectively, is determined by a settable drive value.
Claim 2
Dependent Claim
79 words
Hydraulically operating sausage-filling-and turn-off machine, comprising a rotating feeding pump adapted to feed filling material, a hydraulic motor with settable feeding duration driving intermittently said feeding pump for portioning of said filling material, a rotation servo-valve controlling said hydraulic motor, an electric control motor, and a portioning drive driven by said electric control motor and coupled with said rotation servo-valve, whereby the feeding duration of said feeding pump and the portioning, respectively, is determined by a settable drive value.
Claim 3
Dependent Claim
31 words
The machine, as set forth in claim 1, which includes a second hydraulic motor for driving said turning-off machine, and a servo-valve having a drive and controlling said second hydraulic motor.
Claim 4
Dependent Claim
32 words
The machine, as set forth in claim 1, which includes abutment means, and said abutment means limiting adjustably and mechanically a predetermined distance for securing the portioning size in said portioning drive.
Claim 5
Dependent Claim
24 words
The machine, as set forth in claim 1, which includes an infinitely variable settable transmission drive disposed between said portioning drive and said servo-valve.
Claim 6
Dependent Claim
39 words
The machine, as set forth in claim 1, which includes a reversing drive means disposed between said electric control motor driving said portioning drive and said servo-valve for preventing a return of the portioning drive into a starting position.
