Abstract
The disclosure relates to a piezo actuator device, preferably for controlling a dispensing of an application agent onto a component, including: at least one movable valve body for opening and closing at least one valve seat, at least one preferably pivotable actuating arm for actuating the at least one valve body, and a piezo actuator configured to move the at least one valve body to close and/or open the at least one valve seat.
Claims55
A piezo actuator device, that controls dispensing of an application agent onto a component, comprising:
- at least one movable valve body for opening and closing at least one valve seat,
- at least one pivotable actuating arm for actuating the at least one movable valve body, and
- a piezo actuator configured to move the at least one movable valve body to close and/or open the at least one valve seat, wherein the piezo actuator device is connected to an application agent supply and an application agent return for application agent circulation or is connected to at least two application agent supplies, via which different application agents can be supplied.
A piezo actuator device, that controls dispensing of an application agent onto a component, comprising:
- at least one valve body for opening and closing at least one valve seat,
- at least one pivotable actuating arm for actuating the at least one valve body, and
- a piezo actuator configured to move the at least one valve body to close and/or open the at least one valve seat, wherein the piezo actuator device comprises at least two piezo actuators, which are, relative to the longitudinal direction of at least two valve bodies, arranged offset to each other and actuate at least two valve bodies of different lengths.
A piezo actuator device, that controls dispensing of an application agent onto a component, comprising:
- at least one valve body for opening and closing at least one valve seat,
- at least one pivotable actuating arm for actuating the at least one valve body,
- a piezo actuator configured to move the at least one valve body to close and/or open the at least one valve seat, and
- a computing unit configured to control at least two piezo actuators in a phase-shifted manner, for active noise reduction and/or counter noise generation, in particular in such a way that at least two valve bodies encounter their valve seat in a phase-shifted and/or time-shifted manner.
