Abstract

The invention discloses a low-noise modular automotive air dryer. The low-noise modular automotive air dryer comprises a valve body, a drying tank, a pilot control valve and an unloading valve, wherein the drying tank, the pilot control valve and the unloading valve are respectively mounted on the valve body; a rubber piston-type pilot control valve is adopted for the pilot control valve; a diaphragm unloading valve is adopted for the unloading valve; a cavity A, a cavity B, a cavity C, an annular cavity D, an energy absorbing air channel chamber E and a cavity F are arranged in the valve body respectively; a first opening, a second opening, a third opening and a fourth opening are formed in the sides of the valve body. A throttling and pressure dividing structure is adopted for the pilot control valve, so that the unloading valve is controlled to open at different degrees twice, thus the compressed air is exhausted for two times; the automotive noise and the urban environmental pollution are reduced; the human health and the urban environment are protected; the pilot control valve is controlled to open and close more precisely and reliably; the unloading valve is simple and reliable, and long in service life; the driving safety is effectively improved.

Description

【Technical field】 [0001] The invention relates to the field of key parts and components of automobiles, in particular to a low-noise modular air drying, filtering and self-cleaning processor, in particular to a low-noise modular vehicle used for vehicle braking, door and suspension systems Use an air dryer. 【Background technique】 [0002] Automotive air dryers provide complete, clean, and effective compressed air for automotive brakes, doors, and suspension systems, which have a great impact on the safe driving of automobiles and the life of brake system components. The air compressor provides the air source, first enters the input port of the air dryer, and the compressed air passes through the molecular sieve of the drying tank, the filter screen and the filter membrane to make it dry, degrease and filter, and then output from the output port, and The regenerative air storage tank is inflated, and the compressed air at the output port reaches the intake valve of the pilot...
