Sound-insulated compressor arrangement for use in railway vehicle, has ventilator unit discharging exhausted cooling air and designed as radial ventilator to bypass cooling air flow in fitting area
The arrangement has a compressor unit (1) compressing an ambient air, and a drive unit (2) for production of a rotation movement mounted in the compressor unit. The compressor unit and the drive unit are accommodated in a sound-absorbing fitting area with ventilation openings, whose ventilator device is assigned for the production of a cooling air flow. A ventilator unit (10) designed as an axial ventilator supplies fresh cooling air, and another ventilator unit (20) designed as a radial ventilator discharges an exhausted cooling air to bypass the cooling air flow in the fitting area.
