Abstract: An insulated cooler unit that produces cooled air is disclosed. The cooler unit includes, within a thermally-insulated housing chamber, an inlet for introducing air to be cooled, an outlet for exiting of cooled air, an air heat exchanger for cooling air, a first fan. The cooler unit additionally includes a first track member having a first channel member, at least one first sliding member configured to slide within the first channel member. The first fan is connected to the first sliding member and is slidably mounted in the first track member by the at least one first sliding member, and is capable of being slidably moved over a portion of a first length of the first track member.

Abstract: A rotor unit comprises a rotor cylinder which is fastened to a shaft and is rotatably supported via an external bearing. A gear motor is arranged in the interior, which gear motor drives a first double gear wheel in both rotating directions (a, b) via its power take-off shaft and a pinion. The double gear wheel is supported on a disk and a bearing plate in a freewheel bearing and engages with a second double gear wheel. In one rotating direction (b), the freewheel bearing locks the toothed wheel, so that the latter, rigidly together with the disk, is carried along by the pinion. In this way, the second double gear wheel engages serially with one intermediate gear in each instance, wherein every such engagement is exactly positioned by means of a ball catch. In the other rotating direction (a), the motor in each instance turns a number wheel via the aforementioned gears and accordingly sets e.g. one digit of the postage meter machine's value stamp.
