Embodiment Construction

[0021] figure 1 A screw compressor 10 in the sense of an exemplary embodiment of the invention is shown in a schematic sectional view.

[0022] The screw compressor 10 has a fastening flange 12 for mechanically fastening the screw compressor 10 to a drive (not shown in detail here) in the form of an electric motor.

[0023] However, an input shaft 14 is shown via which the torque is transmitted from the electric motor to one of the two spindles 16 and 18 , namely the spindle 16 .

[0024] Screw 18 meshes with screw 16 and is driven by screw 16 .

[0025] The screw compressor 10 has a housing 20 in which the essential components of the screw compressor 10 are accommodated.

[0026] Housing 20 is filled with oil 22 .

[0027] An inlet connection 24 is provided on the housing 20 of the screw compressor 10 on the air inlet side. The inlet connection 24 is designed in such a way that an air filter 26 is arranged on the inlet connection. Furthermore, an air inlet 28 is arranged...

Abstract

The invention relates to a screw compressor system (100) for a utility vehicle, comprising at least one screw compressor (10) and at least one control and / or regulation unit (110) for controlling andregulating the screw compressor (10). Said control and / or regulation unit (110) is designed such that the screw compressor (10) is prevented, for a determined period of time, from re-starting after being stopped.

Description

technical field [0001] The invention relates to a screw compressor system for a commercial vehicle comprising at least one screw compressor and at least one open-loop and / or closed-loop control unit for open-loop and / or closed-loop drive control of the screw compressor. Background technique [0002] Screw compressors for commercial vehicles are known from the prior art. Screw compressors of this type are used to supply the necessary compressed air, for example, to the brake systems of commercial vehicles. [0003] However, the compressed air demand of the brake system fluctuates depending on the operating state of the commercial vehicle, so that the screw compressor is periodically stopped or restarted in response. [0004] If the operating conditions of the commercial vehicle require that the screw compressor be started shortly after the screw compressor has been stopped, an increased pressure can already build up in the screw chamber within a short time after the screw co...
