Claims
- 1. A device for closing a plurality of digestion vessels the openings of which are in each case covered by a cover, comprising
a plurality of positioning spaces for the digestion vessels, the positioning spaces being able to be distributed in a circumferential row and being accessible from outside, and a plurality of closing devices for pressing the covers against the vessels, wherein further positioning spaces are arranged to be offset inwardly from said positioning spaces.
- 2. A device according to claim 1, wherein
the inner positioning spaces are located on a diametrical line which extends between the two adjacent outer positioning spaces.
- 3. A device according to claim 1, wherein
at least two outer positioning spaces and at least one inner positioning space are arranged on one carrier segment.
- 4. A device according to claim 3, wherein
the carrier segment has a common closing device for its positioning spaces.
- 5. A device according to any of claims 1 to 4, wherein
in each positioning space a resilient pressure-generating means (8) for pressing the cover against the vessel is provided and/or a venting device which automatically opens at an internal pressure which exceeds a given value is provided.
- 6. A carrier segment for closing a plurality of digestion vessels the openings of which are covered in each case by a cover, comprising a positioning space above which is arranged a closing device for pressing the cover against the vessel, two opposed side faces of the carrier segment extending in a wedge configuration, characterized in that the carrier segment has at least three positioning spaces, two positioning spaces being arranged on each side of a median of the wedge configuration in the divergent portion of the carrier segment, and one positioning space being arranged in the narrow portion of the carrier segment, the carrier segment having a support column which extends upwardly between the positioning spaces and supports the closing device.
- 7. A carrier segment according to claim 6, wherein
a common closing device is provided for the digestion vessels.
- 8. A carrier segment according to claim 6 or 7, wherein
the support column links a base carrying the positioning spaces and an upper part comprising the support device, the base and/or the upper part having a wedge-shaped configuration.
- 9. A device for closing a plurality of digestion vessels the openings of which are in each case covered by a cover, comprising a plurality of positioning spaces for the digestion vessels, the positioning spaces being distributed around a central support column, wherein
a common closing device is provided for the digestion vessels which is vertically displaceable by means of a screwing part which is journalled in the end portion of the support column is provided, and wherein a roller bearing which takes up an axial screwing force is arranged between the common closing device and the screwing part.
- 10. A device according to claim 9, wherein
the screwing part is a nut which is screwed on to the support column.
- 11. A device according to claim 10, wherein
the closing device has a horizontal disc of a more resistant material than the other material of the closing device and the roller bearing is arranged between the disc and the screwing parts.
- 12. A device for closing a pot-like digestion vessel the opening of which is covered by a cover, comprising
a pressure-applying plunger, a screwing part arranged coaxially with the pressure-applying plunger, a resilient pressure-generating means arranged between the pressure-applying plunger and the screwing part, wherein the screwing part and the pressure-applying plunger fit around one another in a socketed arrangement.
- 13. A device according to claim 12, wherein
an annular wall which fits over the pressure-applying plunger and which is preferably integrally connected to the screwing part extends from the screwing part.
- 14. A device according to claim 12 or 13, wherein
an annular seal is arranged between the annular wall and the pressure-applying plunger.
- 15. A device according to claim 14, wherein
the annular seal is formed by a sealing ring of resilient material which is mounted in an annular groove in the inner circumferential surface of the annular wall or in the outer circumferential surface of the pressure-applying plunger.
- 16. A device for closing a pot-like digestion vessel the opening of which is covered by a cover, comprising
a pressure-applying plunger, a screwing part which fits over the pressure-applying plunger in the manner of a cap and which has in its lower edge portion a screw thread by means of which it can be screwed to an abutment which surrounds the digestion vessel, wherein the abutment is formed by a supporting ring which is fixed to the digestion vessel at the circumference thereof.
- 17. A device according to claim 16, wherein
the digestion vessel has a flange at its edge and the supporting ring is fastened to the outer circumferential surface of the digestion vessel and/or fits under the flange and/or is formed on the flange.
- 18. A device according to claim 16 or 17, wherein
the resilient pressure-generating means is formed by one or more disk springs stacked one on top of another or by a helical spring.
- 19. A device according to claim 16 or 17, wherein
a position-indicating marking is arranged between the screwing part and the abutment.
- 20. A device for closing a pot-like digestion vessel, the opening of which is closable by a cover which preferably can be braced against the cover by means of a closing part, wherein
the cover has passing through it an outlet channel which is closed by means of a valve which automatically opens the outlet channel at an internal pressure in the digestion vessel which exceeds a given value.
- 21. A device according to claim 20, wherein
the outlet channel extends axially, in particular coaxially, from inside to outside and the valve has a valve body which is larger than the outlet channel and is preloaded against the edge of the outlet channel by means of a spring.
- 22. A device according to claim 21, wherein the edge is formed by the stepped face of a widened portion of the outlet channel.
- 23. A device according to claim 22, wherein
a section of the outlet channel branches off in the cover above the stepped face.
- 24. A device according to any one of claims 21 to 23, wherein
a valve body spigot which fits into the outlet channel with a small clearance for movement projects downwardly from the valve body.
