Abstract
A compressor system for a vehicle includes a compressor driven by a drive motor of the vehicle and a suction air conduit for supplying air that has already been precompressed by a turbocharger of the drive motor to the compressor. A mechanism is disposed in the suction air guide for reducing the flow cross-section. The mechanism is able to limit the charging pressure of the already precompressed air supplied to the compressor. A method for controlling a compressor system having a turbocharged compressor limits a charging pressure of the already precompressed air to an adjustable maximum value.
Claims18
A compressor system for use in a vehicle having a drive motor, the compressor system comprising:
- a compressor drivable by the drive motor of the vehicle;
- a suction air conduit supplying to the compressor precompressed air from a turbocharger of the drive motor;
- and
- a flow cross-section reduction mechanism operatively disposed in the suction air conduit, said flow cross-section reduction mechanism limits a charging pressure of the precompressed air supplied to the compressor,
- wherein the compressor is configured to further compress the air precompressed by the turbocharger and supply the further compressed air to a compressed air conditioning system which removes oil, moisture and dirt particles from the further compressed air, said compressed air conditioning system being separate from the drive motor.
A method for operating a compressor system of a vehicle having a drive motor and a turbocharger, the method comprising the acts of:
- driving the compressor via the drive motor;
- supplying air that has already been precompressed by the turbocharger of the drive motor to the compressor via a suction air conduit;
- limiting a charging pressure of the already precompressed air supplied to the compressor via a flow cross-section reduction mechanism operatively disposed in the suction air conduit;
- the compressor further compressing the air precompressed by the turbocharger;
- supplying the further compressed air to a compressed air conditioning system;
- removing oil, moisture and dirt particles from the further compressed air by the compressed air conditioning system, wherein said compressed air conditioning system is separate from the drive motor.
