Dosing system as well as dosing device and docking vessel for a dosing system

摘要

Dosing system for providing a defined volume of a fluid, in particular a liquid or a shapeless material, comprising a dosing device (2) with a housing (4) which a dosing chamber (5) arranged with a displaceable in the longitudinal direction (x) and with an electromechanical Drive (9), in particular linear drive, connected piston (6), wherein two with the metering chamber (5) fluidly connected mechanical check valves are provided, of which the one check valve for the inlet of fluid into the metering chamber (5) openable suction valve (14 ) and the other check valve is a pressure valve (15) which can be opened to the outlet of fluid in the dosing chamber (5), characterized by a closed docking vessel (3), in particular detachably connected to the dosing device (2), which has a reservoir for storage Fluid provided and with the suction valve (14) fluidly connected storage space (20) has wherein the docking vessel (3) is designed such that at least one wall (19) delimiting the storage space (20) is displaceably arranged and / or at least partially elastic in order to adapt to a changing volume of fluid stored in the storage space (20) ,
