ABSTRACT:
A dosing device for filling liquid into containers comprises a filler body and a metering device. The metering device communicates with the interior of a rotary valve through an end cover of the valve housing, the valve including a valve seat and a check valve closure member spring-biased towards the seat. The valve includes first, second and third rotary ports and first and second fixed ports. Downstream of the second fixed port is an anti-drip suction-producing device of a piston-and-cylinder form whereof the stroke of the piston is adjustable. Upstream of the first fixed port is a throttling valve lowerable into an operative position downstream of inlet holes from a liquid-containing tank. For a high viscosity liquid, it is drawn into the metering device through the holes, the first fixed and rotary ports and the end cover, the rotary valve is rotated to align the second rotary port with the second fixed port and to close the first fixed port, and the liquid is then expelled from the metering device through the end cover, the second rotary and fixed ports and an outlet nozzle. A low viscosity liquid is drawn into the metering device through the holes, the lowered throttling valve, the first fixed and rotary ports and the end cover, and is then expelled from the metering device through the end cover, and check valve, the third rotary port and the second fixed port and the nozzle.
