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.
