Problems solved by technology

[0005] Furthermore, this external volume must be filled with oil, which also increases the total amount of oil
This increases the inertia of the system
In addition, the oil cooler has to be mounted and fastened mechanically, ie either via a surrounding bracket set or via a separate bracket, which requires additional fastening means and installation space

Embodiment Construction

[0021] figure 1 A schematic cross-sectional view of a screw compressor 10 according to an embodiment of the invention is shown.

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

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

[0024] The screw 18 meshes with the screw 16 and is driven via it.

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

[0026] The housing 20 is filled with organic oil 22 .

[0027] On the air inlet side, an inlet connection 24 is arranged on the housing 20 of the screw compressor 10 . The inlet connection 24 is designed here such that an air filter 26 is arranged thereon. Furthermore, an air inlet 28 is arranged radially on the air inlet connection 24 . ...

Abstract

The invention relates to a screw compressor for a utility vehicle comprising at least one female screw (16), at least one male screw (18) that meshes with the female screw (18), and at least one screwcompressor drive which drives the female screw (16).

Description

technical field [0001] The invention relates to a screw compressor for commercial vehicles comprising at least one female screw, at least one male screw meshing with the female screw and at least one screw compressor driver. Background technique [0002] Screw compressors for commercial vehicles are known from the prior art. Such screw compressors are used to supply the necessary compressed air, for example, for the brake systems of commercial vehicles. [0003] In this connection, in particular oil-filled compressors, in particular also screw compressors, are known for which the task of regulating the oil temperature is addressed. This is usually achieved by providing an external oil cooler, which is connected via a temperature control valve to the oil-filled compressor and to the oil circuit. In this case, the oil cooler is a heat exchanger with two separate circuits, wherein the first circuit is provided for the hot fluid, ie compressor oil, and the second A circulatio...
