Problems solved by technology

[0005] Furthermore, this external volume must be filled with oil, thereby also increasing the total amount of oil
Therefore, the inertia of the system increases
In addition, the oil cooler must be mounted and fastened mechanically, either by a nearby holding device or by a separate holding device, which requires additional fastening means and also requires installation space

Embodiment Construction

[0027] figure 1 A schematic sectional view of a screw compressor 10 in the sense of an embodiment of the invention is shown.

[0028] The screw compressor 10 has a fastening flange 12 for mechanically fastening the screw compressor 10 to an electric motor, not shown in detail here.

[0029] However, an input shaft 14 is shown, via which the torque of the electric motor is transmitted to one of the two spindles 16 , 18 , namely the spindle 16 .

[0030] The screw 18 meshes with the screw 16 and is driven via it.

[0031] The screw compressor 10 has a housing 20 in which the main components of the screw compressor 10 are arranged.

[0032] The housing 20 is filled with oil 22 .

[0033] On the air supply side, an inlet connection 24 is provided on the housing 20 of the screw compressor 10 . The inlet connection 24 is designed in such a way that an air filter 26 is arranged thereon. Furthermore, an air inlet 28 is provided radially on the air inlet connection 24 .

Abstract

The invention relates to a screw compressor (10) for commercial vehicles, having at least one housing (20), at least one oil splash baffle (100) and at least one seal (104), said housing There is at least one housing shell (20b) and at least one rotor housing (20a), wherein an oil sump is present in the housing (20) in an assembled state, wherein, with respect to the assembled state, the seal (104) is arranged between the housing cover (20b) and the rotor housing (20a) and protrudes from the oil sump, wherein the seal (104) seals the housing cover ( 20b) and the interior of the rotor housing (20a) are at least partially separated from each other, and wherein the oil surge baffle (100) is substantially above the screw compressor (10) with respect to the assembled state In the case of a horizontal orientation and in the case of a substantially horizontal orientation of the oil sump, it is oriented substantially parallel to the upper horizontal level of the oil sump.

Description

technical field [0001] The invention relates to a screw compressor for commercial vehicles, the screw compressor having at least one housing, at least one oil splash baffle and at least one seal, the at least one housing having at least one housing A main body and at least one rotor housing, wherein an oil sump is present in the housing in the assembled state. Background technique [0002] Screw compressors for commercial vehicles are known from the prior art. Such screw compressors are used, for example, to supply the necessary compressed air for the brake systems of commercial vehicles. [0003] In this connection, in particular oil-filled compressors are known, in particular also screw compressors, in which the task of regulating the oil temperature is present. This is usually achieved by providing an external oil cooler, which is connected to the oil-filled compressor and the oil circuit via a thermostatic valve. The oil cooler is here a heat exchanger with two separa...
