FIELD: machine engineering, namely locking preventing devices of braking systems of transport vehicles having pneumatic or pneumo-hydraulic drive of brakes.
SUBSTANCE: electropneumatic pressure modulator includes housing with inlet and outlet ducts and with exhaust duct; groove for sealing ring; lid with exhaust duct; noise silencer. In groove of housing formed along perimeter of release duct plate is arranged; said plate is made of latticed material, for example of polymeric materials and it repeats contour of exhaust duct and serves as noise silencer. Plate is fixed by means of sealing ring due to forcing it by means of lid to housing.
EFFECT: lowered noise degree of air exhaust to atmosphere, simplified manufacturing process and easy mounting of noise silencer in electropneumatic pressure modulator.
