FIELD: engines and pumps.
SUBSTANCE: invention can be used in ICE exhaust systems. Proposed assembly serves to admix liquid reducer into waste gas flow and comprises proportioning pump (2). Inlet of aforesaid pump is furnished with element connecting it to reducer tank (4), while pump outlet is connected with pressure line (16). Return line (10) connects pump outlet with aforesaid reducer tank (4). Pressure tank (16) accommodates check valve (20) to response to fluid medium pressure generated by proportioning pump (2). Return line (10) communicates with pressure line (16) and accommodates shut-off valve (12) to shut off return line selectively.
EFFECT: simplified design.
