The invention relates to a device for pressurising a closed compartment 5 containing a pressure medium such as oil, grease, a plastic mass or similar, and where the pressurising means consists of a removable standard 19 which is stationary, mounted in a part 8 of a machine member or similar, and in which a part 22 forms a stationary pressure piston 22. The pressure piston 22 cooperates with a movable cylinder 24 which contains a surplus of pressure medium and which can be screwed in over the piston 22. The standard has an axial canal 26 which cooperates with the closed compartment 5 to be pressurised, and by drifting in the movable cylinder 24, 25 over the pressure piston 22, the pressure medium is pressed through the axial canal 26 and pressurises the closed compartment 5. The standard 19 is adequately mounted in an internally threaded hole 16 in the machine member 8, and the cylinder 25 is constituted by an internally threaded hole in a screw 24. The standard 19 has a smaller diameter than the threaded hole, such that the screw 24 may be screwed down around the piston part 22 of the standard. <IMAGE> |
