Abstract

A description is given of a filling system for the metered delivery of a lubricant, comprising a container for receiving the lubricant, wherein a rod interacts with the container, is mounted movably with respect to it and forces the lubricant out of an outlet opening arranged in the container. The invention also relates to cartridges for use in the filling system. One of the underlying objects of the invention was that of providing a filling system which can be supplemented by simple workshop means and enables the operator to fill up a lubricating system in a vehicle effortlessly within a short time. This object is achieved by a filling system in which the rod is rotatably mounted with respect to the container and turning of the rod in a predetermined direction of rotation brings about a reduction in the storage volume in the container or a handheld device and in which the rod has means for establishing a rotationally fixed connection with an adaptable turning tool.

Claims

1. A filling system for the metered delivery of a lubricant, comprising:

a container for receiving the lubricant wherein a rod interacts with the container, is mounted movably with respect to it, and forces the lubricant out of an outlet opening (4) disposed in the container;

wherein

the rod is rotatably mounted with respect to the container, and rotation of the rod in a predetermined direction of rotation brings about a reduction in the storage volume in the container or a manual device; and

the rod has means for establishing a rotationally fixed connection with an adaptable rotating implement.

2. The filling system according to claim 1;

wherein the container comprises a cartridge inside which a displaceable piston is disposed;

wherein the rod is in the form of a spindle.

3. The filling system according to claim 2;

wherein the spindle inter-engages with a thread disposed in the cartridge.

4. The filling system according to claim 2;

wherein the piston and spindle are together of unit construction.

5. The filling system according to claim 2;

wherein the lubricant is disposed on the side of the piston which is directed toward the spindle.

6. The filling system according to claim 3;

wherein the outlet opening and the thread are on the same side of the cartridge.

7. The filling system according to claim 2;

wherein the cartridge is inserted into a manual apparatus wherein the spindle inter-engages with a thread disposed in the manual apparatus, and in that the end of the spindle presses against the piston.

8. The filling system according to claim 2;

wherein the lubricant is disposed on the side of the piston which is directed away from the spindle.

9. The filling system according to claim 3;

wherein the outlet opening is disposed in the side of the cartridge which is opposite to the thread.

10. The filling system according to claim 1;

wherein the container comprises a lubricant bag inserted into the manual apparatus, and the rod is in the form of a spindle which inter-engages with a thread disposed in the manual apparatus, wherewith the end of the spindle is in the form of a piston.

11. The filling system according to claim 1;

wherein the container comprises a cartridge inside which a piston is displaceably disposed;

wherein a region (segment) of the rod inside the cartridge is in the form of a spindle, and the piston is guided with the aid of a thread on the spindle.

12. The filling system according to claim 11;

wherein the rod is radially mounted in opposite end walls of the cartridge, and is held axially with respect to the cartridge.

13. The filling system according to claim 11;

wherein the lubricant is disposed between the piston and the outlet opening.

14. The filling system according to claim 11;

wherein the piston is held on its periphery to prevent it from rotating.

15. The filling system according to claim 2;

that wherein the piston is moved in the axial direction by rotating the spindle.

16. The filling system according to claim 1;

wherein the container is comprised of a lubricant bag which is inserted into a manual apparatus and is fixed to the rod at an attachment side.

17. The filling system according to claim 16;

wherein the lubricant bag has an outlet opening on its side opposite to the attachment side.

18. The filling system according to claim 1;

wherein the rod is in the form of a first toothed shaft, and the container comprises a lubricant bag, wherewith the teeth of the first toothed shaft inter-engage with the teeth of a second toothed shaft, and at least one insertion side of the bag is inserted between the toothed shafts.

19. The filling system according to claim 18;

wherein the side opposite to the insertion side has an outlet opening.

20. filling system according to claim 1;

wherein the outlet opening is adapted to be connectable to a lubricant hose.

21. The filling system according to claim 20;

wherein the lubricant hose has a lubricant nipple connection on its end.

25. The cartridge for use in a filling system according to claim 1;

wherein the cartridge comprises a piston and a spindle which engages the piston, wherewith the spindle engages a thread in the cartridge and on its end bears means for providing a rotationally rigid connection with an adaptable rotational implement.

26. The cartridge for use in a filling system according to claim 1;

wherein the cartridge comprises a rod which extends exteriorly of the cartridge on at least one end, which rod interiorly of the cartridge has a region (segment) in the form of a spindle and has a piston disposed in said segment, which piston has a thread, and said rod also has on (or associated with) its end means for providing a rotationally rigid connection to an adaptable rotational implement.

27. The cartridge according to claim 26;

wherein guide means are disposed on the interior side of the peripheral wall which guide means prevent the rotation of the piston in the circumferential direction.

28. The cartridge according to claim 25;

wherein a breakage site is provided in the transition region between the piston and the spindle.

29. Use of a filling system and/or a cartridge according to claim 1 for filling of a lubrication system for a truck or the like.

22. A filling system for metered delivery of a lubricant, comprising:

a container for receiving the lubricant, wherein a piston which is movably mounted with respect to said container interacts with said container, which piston forces the lubricant out of an outlet opening disposed in the container;

wherein an opening with a connecting flange is formed in the container on the side thereof which is opposite to the side of the piston directed toward the lubricant.

23. The filling system according to claim 22;

wherein a pressure cylinder can be connected to the connecting flange.

24. The filling system according to claim 23;

wherein the pressure cylinder is a CO₂ cartridge.
