FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to metering out of components, particularly, to fuel systems of internal combustion engines and is to be installed in carburetors. Proposed jet for metering out components has calibrated orifice. Constricting part of calibrated orifice is pointed to side of getting components to be metered out and it forms acute angles with outer surface of jet. According to other design version, orifice is pointed with its irregularly constricting part to side of getting of components to be metered out.
EFFECT: provision of self-cleaning and prevention of clogging of calibrated orifice.
