<p>THE INVENTION RELATES TO A DRIVE (1) FOR A COFFEE BREWING DEVICE (2), COMPRISING: A FIRST GEARWHEEL (10) COMPRISING AN INTERNAL THREAD (11), VIA WHICH SAID FIRST GEARWHEEL (10) IS PIVOT-MOUNTED TO AN EXTERNAL THREAD (21) OF A GUIDE CYLINDER (20), SO THAT THE FIRST GEARWHEEL (10) CAN BE MOVED ALONG A CYLINDER AXIS (22) OF THE GUIDE CYLINDER (20) IN RESPONSE TO A ROTATION; A SECOND GEARWHEEL (30), WHICH FOR THE PURPOSE OF DRIVING THE FIRST GEARWHEEL (10) ALONG THE CYLINDER AXIS (22), ENGAGES WITH SAID FIRST GEARWHEEL (10); A HOUSING (50), IN WHICH THE FIRST GEARWHEEL (10) IS ACCOMMODATED; A BREWING PISTON (40), WHICH IS COUPLED TO THE HOUSING (50), SO THAT SAID BREWING PISTON (40) CAN BE MOVED TOGETHER WITH THE FIRST GEARWHEEL (10) ALONG THE CYLINDER AXIS (22) . THE DRIVE (1) COMPRISES A LINEAR GUIDE (80) FOR GUIDING THE HOUSING (50), WHICH RUNS AT A DISTANCE PARALLEL TO THE CYLINDER AXIS (22) AND WITH WHICH THE HOUSING (50) IS ENGAGED IN SUCH A MANNER THAT A MOVEMENT OF THE HOUSING (50) OPPOSITE TO THE LINEAR GUIDE (80) IN A RADIAL DIRECTION TO THE CYLINDER AXIS (22) IS PREVENTED, WHEREIN AN AXIS OF ROTATION (32) OF THE SECOND GEARWHEEL (30) IS ARRANGED IN A PROVIDED DISTANCE RELATIVE TO THE LINEAR GUIDE (80).</p> |
