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 cartridge for use in a filling system, comprising:

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, wherein when the spindle is rotated, the piston is moved in the direction of an outlet opening causing a lubricant to be expelled from the outlet opening, wherein a predetermined breaking point is provided between the piston and the spindle, so the piston shears off from the spindle as soon as the piston is disposed at an end of an axial excursion next to the outlet opening.

2. 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 segment in the form of the spindle and has the piston disposed in said segment, which piston has a thread, and said rod also has on its end a structure for providing the rotationally rigid connection to the adaptable rotational implement.

3. The cartridge according to claim 2;

wherein a guide is disposed on the interior side of a peripheral wall which prevents the rotation of the piston in a circumferential direction.

4. A cartridge for use in a filling system, comprising:

a piston and a spindle which engages the piston, the cartridge having an end wall having an outlet opening, wherein the spindle engages a thread in the end wall of the cartridge which bears the outlet opening, wherein when the spindle is rotated, the piston is moved in the direction of the outlet opening causing a lubricant to be expelled from the outlet opening, and wherein a breaking point is provided between the piston and the spindle that separates the piston from the spindle when the piston is disposed at an end of an axial excursion next to the outlet opening.
