Abstract: An air outlet, in particular for heaters or air conditioning units for recreational vehicles like campers or caravans, having a main housing, a flap suitable to seal the air flow channel in the main housing and a coupling mechanism. The main housing forms an air flow channel and the coupling mechanism couples the flap to the main housing in a movable manner such that the flap can be moved with respect to the main housing between a closed state, in which the flap seals the air flow channel, and an opened state, in which the flap does not seal the air flow channel. The coupling mechanism is configured such that the flap conducts a rotating and sliding movement with respect to the main housing when being moved between the closed state and the opened state.

Abstract: The embodiments relate to a self-supporting articulated-arm cassette awning, in particular for motor homes or trailers, comprising articulated arms (20) that are pivotable at awning arm joints or shoulder joints (10), and brackets or shoulders (II) for connecting the entire awning (100) to the vehicle by means of fastening elements and for receiving joint pins (I) in an insertable, in particular, slidable manner and for at least limiting the twistability of joint pins (I) of those parts of the awning arm joint or shoulder joint that are fixed to the vehicle. Desirable is a compact, continuously variable twisting arrangement for the joint pin which, at the same time, is capable of absorbing the high torques of the extended awning.

Abstract: A centrifugal separator for separating non-gaseous particles from a gas flow having a separator housing enclosing a rotor with a raw gas inlet, a clean gas outlet, and a particle outlet. A circumferential wall encloses the rotor. A raw gas flow is guided axially into the rotor. A clean gas flow is guided out of the rotor and then between the rotor and the circumferential wall to the clean gas outlet. The rotor comprises particle separation elements so that particles separated from the gas flow are centrifuged onto the circumferential wall. The circumferential wall particles are guided to the particle outlet via at least one particle guide trough running diagonal to the rotor axial direction on the interior of the circumferential wall. A radius of each trough as well as the distance between the rotor and the circumferential wall decreases in the direction of the clean gas flow.

Abstract: A crankcase ventilation apparatus of an internal combustion engine of a motor vehicle, including an oil-mist separator for the separation of oil from the crankcase ventilation gas of the internal combustion engine and including an assembly for the return of lubricating oil from the oil-mist separator to an oil pan of the internal combustion engine. The oil-mist separator includes at least one preliminary separator and at least one fine separator, wherein the preliminary separator is connected to the oil pan via a first oil return flow passage allowing a continuous flow of oil there through during operation and wherein an oil collection chamber is provided downstream of an oil outlet of the fine separator, said oil collection chamber being connected to the oil pan via a second oil return flow passage which is equipped with a check valve to discontinue the flow of oil during operation.
