Vehicle cab with a pressurised interior

摘要

The invention relates to a vehicle cab in an atmosphere loaded with pollutants, having a system (9) for supplying the cab interior with respirable air which is set to a cab internal pressure above the ambient pressure, and having at least one sensor (10) which detects the state of the air flow in the atmosphere surrounding the vehicle cab (4) and is connected to the system (9) so as to influence the cab internal pressure. The intention is to improve the capability of adjusting the cab internal pressure. To achieve the object it is provided that the sensor be constructed as a transmitter (10, 13) which measures at least the pressure of the air flow in conjunction with the direction of the air flow, or the pressure of the air flow in conjunction with the speed of the air flow, or the pressure of the air flow in conjunction with the direction of the air flow and the speed of the air flow. <IMAGE>
