Abstract: A coffee machine for the preparation of pressure-extracted coffee with a low particle content is provided. The coffee machine differs from known machines for pressure-extraction of coffee by comprising a filter element for reducing the particle content of coffee, which filter element is disposed downstream of the percolating sieve and is connected fluidically to the percolating sieve and to the outflow. By means of the filter element, coffee extracted by pressure in the percolating unit can be filtered before dispensing the outflow so that suspended particles and emulsified oils of a specific size are separated from the coffee by the filter element and a new coffee is produced. In addition, the coffee machine can prepare standard pressure-extracted coffee since the coffee from the percolating unit can also be guided past the filter element, i.e. need not flow necessarily via the filter element to the outflow.

Abstract: The present invention relates to an oil separator for separating oil and/or oil mist from a gas. An optimum separation performance is hereby achieved with normal volume flow of the gas (A) but also in the case of an increased volume flow (A) or a blockage of the oil separator, the ventilation for example of a crankcase is ensured and observance of a maximum pressure loss is ensured. For this purpose, two oil separation elements (10a to 10d and 10e to 10h) are disposed one behind the other in the volume flow (A), the spacing of which from each other is variable.

Abstract: An air treatment module, in particular for thermal treatment of air to be introduced into the vehicle interior of a vehicle, includes a support arrangement to be fixed to a vehicle, a fan arrangement supported by the support arrangement, a first heat exchanger arrangement, supported on the support arrangement, for thermal treatment of air forwarded by the fan arrangement, further including a heating device and a second heat exchanger arrangement receiving heat from the heating device, the heating device and the second heat exchanger arrangement being supported on the support arrangement.
