LEVER-OPERATED DISPENSING UNITS FOR COFFEE MACHINES

摘要

A dispenser unit operated by a lever for use in espresso machines. The lever is associated with an electric motor which, as selected by an operator, at least partially relieves the effort required to displace the lever for loading the spring that actuates the coffee dispensing piston. The same electric motor acts as a brake during the return movement of the lever that loaded the spring of the dispensing piston of the unit. In case of failed coffee dispensing, the braking motor provides an accident-prevention safety feature by preventing any abrupt return movement of the lever.
