Electric motor-driven syringe dispenser, has a pump for driving a working piston-cylinder combination that is coupled to the syringe piston, with the pump driven by an electric motor

摘要

Dispenser has an electric motor drive with an arrangement (2) for detachable attachment of a syringe (3); an arrangement with a working cylinder (9) and piston (7) for driving the syringe piston (3d); a coupling for linking the working piston to the syringe piston and; a pump driven by the motor for conveying a hydraulic medium to the working chamber (9a, 9b) of the working cylinder so that the piston is driven by the hydraulic medium.
