Embodiment Construction

[0020] figure 1 A schematic cross-sectional view of a screw compressor 10 according to an embodiment of the invention is shown.

[0021] 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.

[0022] 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 .

[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 main components of the screw compressor 10 are accommodated.

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

[0026] 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. In addition, an air inlet 28 is arranged radially on the air inlet connecting pi...

Abstract

The present invention relates to a screw compressor (10) for a utility vehicle, comprising at least one housing (20) and a relief valve (80), wherein the relief valve (80) comprises a spring-loaded closure mechanism (100) with at least one spring (102) and at least one closure element (104), the spring (102) having a spring force which is dimensioned such that it actuates the closure element (104) when a predefined minimum pressure above the atmospheric pressure is reached.

Description

technical field [0001] The invention relates to a screw compressor for commercial vehicles having at least one housing and a pressure relief valve. Background technique [0002] Screw compressors for commercial vehicles are known from the prior art. Such screw compressors are used to supply the compressed air required, for example, for the braking system of a commercial vehicle. [0003] In this respect, in particular oil-filled compressors, in particular also screw compressors, are known in 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 thermostat valve to the oil-filled compressor and 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 the compressor oil, and the second circuit is provided for the cooling fluid. As cooling fluid, air, water mixtures with antifreeze or ...
