ABSTRACT:
The material to be metered fills the cylinder 1 when it is in front of the admission orifice 31, whereupon the cylinder 1 moves opposite the delivery orifice 32 where the piston 2 describes a movement towards top dead center in order to eject said material out of the cylinder 1. The cylinder 1 then moves towards the admission orifice while the piston 2 remains at top dead center to avoid any return flow, whereupon the cycle starts over again.
