Definitions
- the invention relates to a silencer for compressed air devices according to the preamble of claim 1.
- DE 42 37 630 A1 discloses a compressed-air venting device which has a main air path guided from an inlet of a housing to a discharge via noise-damping means and an auxiliary air path provided parallel to it and which consists of a first part-passage starting from the inlet and one from the outlet ge formed or leading to the outlet second sub-channel be ⁇ stands.
- the two subchannels are not filled with the noise-damping means.
- the two sub-channels are connected mit ⁇ each other via the noise-damping means.
- the two subchannels and the part of the noise damping means connecting the two subchannels are arranged so that this part of the noise damping means releases a direct connection between the two subchannels during the impact with a back pressure.
- the noise dampening means are formed by a filter knit consisting of a stocking fabric part made of plastic flat wire, which is wound into a roll.
- the housing is composed of a cup-shaped housing part and a snapped on this, designed as a disgusting housing part.
- a disadvantage of this compressed air venting device serving as a noise damper is that there is a risk of leaks at the joints of the housing parts which cause a high level of noise.
- the known device is relatively large and therefore requires much Einbau ⁇ space.
- the object of the present invention is to provide a noise damper of the type mentioned above, which achieves better noise damping while realizing high venting gradients and which can be installed even in very confined spaces in the vehicle and is easy to manufacture.
- the invention provides a noise damper for compressed air devices, for example for Druck Kunststoffbremsanla ⁇ gene available, which is extremely small, consists of easy-to-produce components and significantly improved by a novel air duct noise reduction.
- the required for compressed air systems high venting gradient is maintained despite greater sound attenuation.
- FIG. 1 shows a perspective side view of a noise damper according to the invention with a view of an air inlet nozzle
- Fig. 2 shows a section A-A through the noise damper of Figure 1 and
- FIG. 3 shows a section B-B through the noise damper of Figure 2.
- FIG. 1 shows in FIG. 1 a noise damper 2 with a housing 4 which consists of a central tubular part 6 and two cylindrical housing caps 8, 10, which are latched onto the ends of the tubular housing part 6 and also are removable again.
- the housing caps 8, 10 have a cap base 12, 14 and a cylindrical shell 16, 18.
- 14 radial slots 20, 22 are formed, which extend beyond a transition region 24, 26 also into a cap bottom adjacent part 16 ', 18' of the shell 16, 18 and outlets 28, 30 of the noise damper 2 bil ⁇ the.
- the tubular part 6 of the housing 4 has a molded, centrally arranged inlet pipe 32 with inlet opening 33 for compressed air and two flanges 24, 36 with Mon ⁇ tagelöchern 38, 40, with which the noise damper 2 angeord example of the housing of a vent valve ⁇ net is (not shown), such that the matterssstut- zen 32 is practically directly connected to the valve outlet.
- the inlet nozzle 32 is formed and arranged such that the air to be vented to the atmosphere flows essentially tangentially to the knitting roll 42 centrally into the tubular housing part and the knitting roll, then is deflected radially to both sides and axially the knitting roll 42 of the housing part 6 and the two knitted rolls 44, 46 of the housing caps 8, 10 flows through and finally flows out of the outlets 28, 30.
- the tubular housing part 6 may be equipped with only one housing cap and formed closed on one side, so that the air flowing into the noise damper 2 air is deflected radially to one side only and axially flows out only from one outlet.
- Such a silencer acts as an acoustic monopole.
- the noise damper embodied according to the invention influences the turbulent flow in the free air jet in such a way that the sound emission is reduced or the noise or sound attenuation is increased during a venting operation, whereby the required functions are ensured in the existing installation space, in particular the prescribed conditions Ventilation times after braking are maintained.
- the noise damper according to the invention can be produced in a simple manner from plastic, whereby a housing cover can also be formed in one piece with the tubular housing part.
- a cap is preferably releasably mounted, so that an exchange of the knitting rolls is possible.
- the noise damper according to the invention is very small, so that mounting in the vehicle is possible even in very restricted space conditions.
- At least one further outflow opening 50 is arranged.
- At least one further outflow opening analogous to the outflow opening 50 is formed only in the tubular housing part 6 and wei ⁇ sen the housing caps 8, 10 no outlets on, so are closed.
- At least one of the housing caps 8, 10 can be dispensed with, wherein preferably the cap-free end of the tubular housing part 6 is designed to be closed.
