Abstract
A dosing system for a liquid or viscous dosing material, including an actuator system, that has at least one actuating element and a nozzle with an outlet opening. The dosing system is designed so that during a movement in a closure direction the actuating element is initially moved in a first partial movement in such a way that the actuating element is separated from the closure element at a stop location, intended for that purpose, and then comes into contact with the closure element at the stop location and exerts an impulse on the closure element. This also relates to a corresponding dosing method.
Claims11
A dosing system for a liquid or viscous dosing material, the dosing system comprising
- a nozzle with an outlet opening,
- a closure element, and
- an actuator system having a piezoelectric actuator and at least one actuating element comprising a lever which temporarily connects the piezoelectric actuator with the closure element,
- whereby the dosing system is designed so that during a movement in a closure direction the actuating element is initially moved in a first partial movement in such a way that the actuating element is separated from the closure element at an intended stop location, and then strikes the closure element at the stop location and exerts an impulse on the closure element.
A method of dosing a liquid or viscous dosing material with the aid of a dosing system, including
- a nozzle with an outlet opening, a closure element and an actuator system, that has a piezoelectric actuator and at least one actuating element comprising a lever which temporarily connects the piezoelectric actuator with the closure element,
- the method comprising the steps of
- initially moving the actuating element in a first partial movement in such a way that the actuating element is separated from the closure element at an intended stop location, and then strikes the closure element at the stop location and exerts an impulse on the closure element.
