Problems solved by technology

However, such a solution is quite bulky and has only a limited sound dampening effect
[0006] In addition, the mufflers known from the prior art have the disadvantage that condensate contained in the compressed air freezes in the muffler, thereby possibly blocking the outlet of the compressed air to the outside

Embodiment Construction

[0029] according to figure 1 , a double-chamber air drying equipment includes two drying containers 1a and 1b, these drying containers operate alternately in two states, namely a dry state and a regeneration state, to ensure the continuous flow of moist compressed air dry.

[0030] While the main air flow in one of the drying vessels 1a is being dried, the desiccant in the other drying vessel 1b is regenerated by reverse operation. These state phases are carried out via a switching valve 2 in accordance with the commands of the electronic control unit 3 . On the outlet side of the on-off valve 2 a silencer is connected via a line 4 . To this end, the line 4 engages an inlet opening 5 on the silencer housing. This inlet port 5 is used to feed in the condensate-containing compressed air to be discharged from the air drying plant. The sound attenuation device is used to dampen the outflow noise acoustically and at the same time to reliably discharge the condensate contained i...

Abstract

A sound suppressor device for an air drying unit of a compressed-air supply system having a sound suppressor housing on which is arranged an inlet opening for the supply of condensate-laden compressed air to be discharged from the air drying unit and at least one outlet opening for the discharge of the condensate-laden compressed air to the outside, wherein the inlet opening issues into at least one pre-chamber of the sound suppressor housing, which pre-chamber issues into post-chambers which are connected in parallel and which are arranged around a heating rod arranged centrally in the sound suppressor housing.

Description

technical field [0001] The invention relates to a muffler device for air drying equipment of a compressed air supply system, which comprises a muffler housing, on which an inlet and a discharge are arranged, and the inlet is used for inputting air The compressed air containing condensate discharged from the drying equipment, the discharge port is used to discharge the compressed air to the outside. Background technique [0002] The field of application of the invention mainly relates to rail vehicles, the compressed air supply system of which is mainly used to provide braking pressure for vehicle braking. In order to generate brake air that is as dry as possible, the compressor-driven compressed air supply system for the preparation air includes an air drying device that extracts compressed air from the outside Contains moisture away. For this purpose, in rail vehicle construction mainly single-chamber and double-chamber air dryers are used, which extract the moisture from...
