Abstract:
1. Device for dispensing a dental composition, comprising a plunger for extruding the dental composition from a container, an energy accumulator connectable to the plunger to advance the plunger at an extrusion force, an actuator which can be actuated for charging the energy accumulator, and a one-way clutch being movable by the actuator, wherein the device further comprises a force converter which allows the actuator to be actuated at an actuation force that is lower than the extrusion force available from the energy accumulator to advance the plunger; and wherein the one-way clutch is adapted to retract the plunger when moved in a first direction, but is movable relative to the plunger when moved in a second direction opposite the first direction.
