Patent

CA 2623987

The invention provides an actuator for actuating a pallet of a pipe organ under the command of a key of an organ. The actuator comprises a movable member, adapted to be connected to the pallet of the organ pipe and a magnetic plunger, mounted on the movable member. It also comprises an electromagnet having a gap within which the magnetic plunger can be inserted and moved, wherein the electromagnet when energized moves the member to thereby actuate the pallet. A controller unit controls a current in the electromagnet to provide a controlled actuation of the pallet that is proportional to a key dip of the key. It also provides for a system based on a digital serial link for controlling an assembly of organ pallets that are actuated by electromagnets.

Actionneur permettant d'actionner une palette d'un organe de tuyauterie sous la commande de la touche d'un organe. L'actionneur comprend un élément mobile, conçu pour être raccordé à la palette de la tuyauterie, et un plongeur magnétique monté sur l'élément mobile. L'actionneur comprend également un électroaimant comportant un espace dans lequel le plongeur magnétique est inséré et se déplace, l'électroaimant, une fois énergisé, déplace l'élément pour actionner la palette. Une unité de commande commande le courant de l'électroaimant afin d'assurer un actionnement commandé de la palette proportionnel à l'enfoncement de la touche. Système utilisant un lien numérique en série pour commander un ensemble de palettes actionnées par des électroaimants.
