Problems solved by technology

[0004] However, a conflict of objectives arises when using such devices for supplying compressed air, namely a short filling time (charging time, Auffüllzeit) is required which requires a compressor with a high supply capacity

Embodiment Construction

[0039] figure 1 A schematic diagram of a device 10 for supplying compressed air according to the prior art is shown. In this example, a two-stage piston compressor 20 is used for generating the compressed air, which is driven by an electric motor 23 . The compressor 20 has a first compression device 21 and a second compression device 22 . In this exemplary device 10 for supplying compressed air, ambient air is sucked in through an air filter 11 and supplied via an air supply line 24 to a first compression device 21 . Compressed air at a first pressure is generated during the subsequent flow through the first compression device 21 . The first pressure of the compressed air is about 3.3 bar (absolute) in the device 10 .

[0040] Compressed air at a first pressure is introduced into the second compression device 22 via a connecting line 25 . An intermediate cooling device 12 is provided on the connecting pipe 25 , and the intermediate cooling device cools the compressed air i...

Abstract

The invention relates to a device for compressed air supply, in particular for a rail vehicle, which is operable in a normal mode and an auxiliary air mode. According to the invention, the device hasa compressor having a first compression device and a second compression device, wherein the compressed air can be conducted through a connection line from the first compression device to the second compression device. The connection line is functionally connected to a switching mechanism by means of which the connection line can be connected to air under environmental pressure in the auxiliary airmode.

Description

technical field [0001] The invention relates to a device and a method for supplying compressed air, in particular to rail vehicles, having a compressor with a first compression device and a second compression device connected to the first compression device via a connecting line. Background technique [0002] Devices for supplying compressed air are used in rail vehicles, in particular for supplying compressed air to braking systems of rail vehicles. For auxiliary units, such as pantographs, often smaller auxiliary air compressors are used, supplied for example from the vehicle battery of the rail vehicle for auxiliary compressed air for the servo drives of the pantographs or similar mechanisms electrical energy. The electrical energy of the vehicle battery is sufficient to electrically drive this auxiliary air compressor, which is of a small design, so that sufficient compressed air can be generated for the auxiliary air supply. However, a disadvantage of such a device fo...
