Patent ID: 8733232

Claim:
A drive for a brewing device, comprising: a first gearwheel defining an internal thread, via which said first gearwheel is pivot-mounted on an external thread of a guide cylinder, so that the first gearwheel is configured to move along a cylinder axis of the guide cylinder in response to a rotation; a second gearwheel configured to engage with said first gearwheel to drive the first gearwheel along the cylinder axis; a housing, in which the first gearwheel is accommodated; a brewing piston, which is coupled to the housing, so that said brewing piston is configured to move together with the first gearwheel along the cylinder axis; and a linear guide configured to guide the housing, which runs at a distance parallel to the cylinder axis and with which the housing is engaged such that the housing is configured to perform a linear movement along the linear guide and a movement of the housing opposite to the linear guide in a radial direction to the cylinder axis is prevented, wherein the second gearwheel defines an axis of rotation arranged in a provided distance relative to the linear guide.
