AIR PREPARATION DEVICE FOR MOTOR TRANSPORT Russian patent published in 2020 - IPC F15B21/48 B60T17/00 B60R16/08 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Device (1) of air preparation for motor transport contains at least first union (2.1) of compressed air and second union (2.2) of compressed air, as well as first component (3.1) of air preparation and second component (3.2) of air preparation. First air preparation component (3.1) comprises at least first magnetic valve (MV1), second magnetic valve (MV2) and third magnetic valve (MV3), first air-drying cartridge (4.1), first main check valve (5.1), first regenerative check valve (6.1), first regenerative throttle (7.1) and first inlet valve (9.1). Second component (3.2) of air preparation has at least a second air-drying cartridge (4.2), second main check valve (5.2), second regenerative check valve (6.2), second regenerative throttle (7.2), and second inlet valve (9.2). At that, the first magnetic valve (MV1) and the second magnetic valve (MV2) are intended for control of the first air preparation component (3.1). Control line (11) is installed so that to connect second component (3.2) of air preparation with the third magnetic valve (MV3) of first component (3.1) of air preparation.

EFFECT: technical result consists in providing a simple design of the air preparation device, as well as controlled regeneration.
