Abstract
The machine provides for metering liquid pharmaceutical products into bottom shells, and has: a bottom part rotating about a respective vertical axis; a number of first vertical through holes formed in the bottom part; a piston movable reciprocatingly along a respective first hole; a bottom-shell belt meshing with a portion of the bottom part; a rotary top part defined by a vessel containing the pharmaceutical product; a rotary central part coaxial and angularly integral with the bottom part and the top part; a second hole, for each first hole, formed radially along the central part; and a valve housed in each of the second holes. Two separate channels are formed in the valve; and the valve rotates between a first angular position in which a first channel hydraulically connects the inside of the vessel to a metering chamber defined along the first hole, and a second angular position in which a second channel hydraulically connects the chamber to the inside of the bottom shell.
