Abstract

An arrangement for the metered feed of a fuel, especially in the combustion space of an internal combustion engine, includes a valve guided and actuatable in a valve body via a stem which intermittently controls a discharge opening arranged in the valve body. The stem of the valve is hollow for the formation of a reservoir chamber which enables the arrangement to be used for a cryogenic gaseous fuel. Channels are arranged in the stem and connect the reservoir chamber with an overflow chamber in the valve body which is arranged adjacent the discharge opening. The channels can be swirl channels.
