Abstract: A mixer, which forms the core part of an air-conditioning assembly of a rail vehicle, has two inlets, an outlet, and a central region between the inlets and the outlet. A first inlet is connected to a fresh air supply, and a second inlet is connected to a circulating air supply such that fresh air and circulating air reach the central region, where the circulating air is mixed with the fresh air to obtain supply air. The central region is connected to the fresh air inlet via an opening, which forms a transition region between the fresh air inlet and the central region. The transition region contains a profiled section with a wing-shaped cross-section in the transition region where the supplied fresh air generates negative pressure along the transition region, and the circulating air is suctioned into the central region of the mixer with a boost from the negative pressure.

Abstract: A ventilation module for a rail vehicle contains a housing having an air inlet, an air outlet, a dust discharge opening, a first cleaning station in an upper region of the housing, a cyclone separator which has a dust outlet and a cyclone air outlet. A second cleaning stage is disposed in a central region of the housing, which is arranged underneath the first cleaning stage such that air from the cyclone air outlet can reach the second cleaning stage. A dust discharge channel is connected to the dust outlet and is arranged in the central region. A dust discharge fan is set up to extract air and dust from the dust discharge channel and to remove the same through the dust discharge opening. A machine room fan is arranged in a lower region of the housing and is set up to extract air through the second cleaning station.

Abstract: A rail vehicle or locomotive includes a machine compartment, a cooling air flow system supplying the machine compartment, and a separating device separating particles from the air flow. The separating device includes a cyclone separator, a raw air channel feeding a raw air flow with particles to the separator and a clean air channel leading a clean air flow away from the separator. The separator has a box-shaped housing having a plurality of cyclones penetrating the housing for separating particles from the raw air flow into the housing and a discharge opening discharging separated particles from the housing. The discharge opening is connected to a constricted section of a Venturi nozzle suctioning an exhaust air flow having discharged particles. The Venturi nozzle is connected to the raw air channel by a branching side channel. The vacuum at the discharge opening suctioning the exhaust air flow is compact and economical.
