摘要：
The device comprises at least one unit having a metering chamber (38) in which a piston (26) follows a reciprocating motion between a filling position and a discharge position. The metering chamber is at least partially defined in a cylinder (24) in which the piston moves, which cylinder is arranged in a vessel (10) that itself follows a reciprocating motion between an open position in which a feed port (36) of the cylinder is opened and a closed position in which the feed port is sealed. The piston is connected to a controlled reciprocating motion mechanism.
