FIELD: electro-pneumatic sound signals engineering used for construction of vehicles. ^ SUBSTANCE: electro-pneumatic signal 1,100,200 has electro-compressor block 2 for producing compressed air, sound wave generator, containing at least one acoustic chamber 7,8,107,108, connected to channel 13,14,213 shaped like coil, for sending generated sound outwards. Means for channeling air 4 connects compressor block 2 to each acoustic chamber 7,8,107,108. compressor block 2 and sound wave generator 3 are mechanically connected due to sliding mounting of yoke 34, 234. ^ EFFECT: compact structure of signaling device, simplified process for assembling and dismounting the same during maintenance. ^ 1 cl, 18 dwg |
