<p>The drive (1) has a gear wheel with an inner thread, over which the gear wheel is rotatably supported on an external thread (21) of a guide cylinder (20). Another gear wheel (30) is engaged with the former gear wheel for driving the former gear wheel along a cylinder axis (22). A linear guide (80) is provided for guiding a housing (50) which runs at a distance parallel to the cylinder axis and with which the housing remains in contact such that a movement of the housing in a radial direction to the cylinder axis opposite the linear guide is prevented. An independent claim is also included for a coffee brewing device with a damping element.</p> |
