FIELD: transportation. ^ SUBSTANCE: air distributor consists of the primary and mainline sections with a two-chamber reservoir with a movable partition arranged in the mainline section separating the latter and control valve section incorporating a plunger, a seat inside the orifice of which a plunger part with throttling orifices interconnecting the mainline, control valve and intermediate sections of the working chamber is arranged. On the seat outward bulge, there is a throttling orifice that communicates the working chamber intermediate space with two-chamber reservoir working space via a channel. The channel incorporates an additional throttle made in the form of several washers with intermediate chambers to facilitate clearing of the additional throttle orifices and possessing a capacity sufficient, if taken together with the capacity of the seat throttling orifice, to ensure a required gas flow rate in operating conditions of air distributor. ^ EFFECT: increase of reliability and maintainability and reduction in clogging of the throttle orifices. ^ 2 cl, 1 dwg |
