Problems solved by technology

[0005] Furthermore, this external volume must be filled with oil, so that the total amount of oil also increases
This increases the inertia of the system
In addition, the oil cooler must be mounted and fastened mechanically, either by means of a surrounding mounting or by means of a separate mounting, which requires additional fastening means but also requires installation space

Embodiment Construction

[0020] figure 1 A screw compressor 10 in the sense of an exemplary embodiment of the invention is shown in a schematic sectional view.

[0021] The screw compressor 10 has a fastening flange 12 for the mechanical fastening of the screw compressor 10 to an electric motor, not shown in detail here.

[0022] 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 .

[0023] The screw 18 meshes with the screw 16 and is driven via it.

[0024] The screw compressor 10 has a housing 20 in which the essential components of the screw compressor 10 are accommodated.

[0025] The housing 20 is filled with oil 22 .

[0026] On the air supply side, an inlet connection 24 is provided on the housing 20 of the screw compressor 10 . In this case, the inlet connection 24 is designed such that an air filter 26 is arranged thereon. Furthermore, an air inlet 28 is provided radially on the air...

Abstract

The invention relates to a screw compressor (10) for a utility vehicle comprising an air filter (26) with an intake port (24) and an air supply channel (32) for supplying air to the screws of the screw compressor (10), the intake port (24) is arranged between the air filter (26) and air supply channel (32) and comprises a pocket groove (100) which can maintain the oil.

Description

technical field [0001] The invention relates to a screw compressor for a commercial vehicle, comprising an air filter, an inlet connection and an air supply channel for supplying air to a screw of the screw compressor. Background technique [0002] Screw compressors for commercial vehicles are already known from the prior art. Such screw compressors are used to provide the necessary compressed air, for example, for the braking system of a commercial vehicle. [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 arises. This is usually achieved by having an external oil cooler which is connected to the oil-filled compressor and the oil circuit via a thermostatic valve. In this case, the oil cooler is a heat exchanger with two separate circuits, wherein a first circuit is provided for hot liquid, ie compressor oil, and a second circuit is provided for cooling liq...
