Abstract

A dosing device comprises a housing. The housing has a slot-shaped opening in the axial direction. The respective region of a setting cylinder located inside the housing can be seen from the exterior through the opening. The setting cylinder can be radially rotated or set by way of a setting wheel. Quantitative indications of the discharge volumes for various syringe types at various settings are arranged in columns on the setting cylinder in the form of a table. The cylinder is oriented relative to the window in the housing such that at a given angular setting of the cylinder the correct discharge volume is visible in the window for every syringe type.
