Definitions
- the present invention relates to a screw compressor for a commercial vehicle having at least one housing and at least one Luftölabscheider-Halter arranged on the housing.
- Screw compressors for commercial vehicles are already known from the prior art. Such screw compressors are used to provide the necessary compressed air for, for example, the braking system of the commercial vehicle.
- Oil circuit is connected via a thermostatic valve.
- the oil cooler is here
- Heat exchanger having two separate circuits, wherein the first circuit for the hot liquid, so the compressor oil is provided and the second for the cooling liquid.
- a coolant for example, air
- Water mixtures can be used with an antifreeze or other oil.
- This oil cooler must then with the compressor oil circuit through pipes or
- Hoses are connected and the oil circuit must be secured against leaks.
- This external volume must also be filled with oil, so that the total amount of oil is increased. This increases the system inertia.

- Aiuminiumgepuse has.
- Screw compressor can be prevented or does not occur at all.
- a screw compressor for a utility vehicle is provided with at least one housing and with at least one arranged on the housing Nursingölabscheiderhalter, wherein the Luftölabscheider holder is made of non-corrosive material and wherein a relief valve is provided, which is arranged in Gutölabscheider holder, by means of the interior of the screw compressor is pressure relieved.
- the invention is based on the idea that the relief valve, whose connections and its surroundings are known to attract moisture precipitation, are arranged at a location in the screw compressor at which corrosion can not take place. In this context, it is envisaged that
- the non-corrosive material at least partially consists of aluminum or at least partially consists of an aluminum alloy.
- a simple production for example, by casting or chip method allows.
- sufficient stability is achievable.
- Aluminum alloys are also useful as suitable non-corrosive materials.
- the relief valve may be connected to the air inlet of the screw compressor. This is a simple construction for pressure relief of
- Screw compressor provided.
- the cross-sections of the air inlet are also well suited to provide a pressure relief.
- connection of the relief valve with the air inlet of the screw compressor at least partially outside of
- Air inlet inside the housing of the screw compressor avoided.
- a simple and reliable connection, which can also be appropriately serviced or provided with spare parts, is thereby possible.
- connection of the relief valve with the air inlet of the screw compressor at least partially by a
- Plastic tube is formed. This is a simple and reliable non-corrosive connection between the relief valve and the air inlet is formed.
- the plastic tube can also be outside the housing of the
- the relief valve can be connected to the atmosphere via the air inlet. This enables a simple and reliable pressure reduction via the air inlet from the relief valve.
- the housing consists of a different material than the Luftölabscheider holder. This allows a more cost-effective and easier production, since it is not absolutely necessary, all components of the screw compressor and not all the housing components of the To manufacture screw compressor made of non-corrosive material. Suitable materials in each case, which also meet the cost requirements, can thus be selected. The cost of the screw compressor can thereby be favorably influenced.
- the housing may be made of a cast material, in particular cast iron. As a result, a simple and inexpensive production is possible.

- the housing 20 is filled with oil 22.
- Air inlet side is on the housing 20 of the screw compressor 10 a
- Inlet port 24 is provided.
- the inlet nozzle 24 is designed such that an air filter 26 is arranged on it.
- an air inlet 28 is provided radially on the air inlet pipe 24.
- a spring-loaded valve core 30 is provided, designed here as an axial seal.
- This valve insert 30 serves as a check valve. Downstream of the valve core 30, an air supply channel 32 is provided, which supplies the air to the two screws 16, 18.
- an air outlet pipe 34 is provided with a riser 36.
- a temperature sensor 38 is provided, by means of which the oil temperature can be monitored.
