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.

First claim

The invention claimed is:

1. A rail vehicle or locomotive, comprising:
a machine compartment;
a cooling air system for supplying said machine compartment with a cooled air flow; and
a separating device for separating particles from the air flow, said separating device including a cyclone separator, a raw air channel leading to said cyclone separator for feeding a raw air flow laden with particles, said raw air channel having a side channel branching off from said raw air channel, a clean air channel leading away from said cyclone separator for leading away a clean air flow, and a Venturi nozzle having a constricted section, said Venturi nozzle being connected through said side channel to said raw air channel;
said cyclone separator including a box-shaped separator housing having a plurality of separator cyclones penetrating said separator housing for separating particles from the raw air flow into said separator housing and a discharge opening for discharging separated particles from said separator housing; and
said discharge opening being connected to said constricted section of said Venturi nozzle for suctioning away an exhaust air flow to which discharged particles have been added.
