Title
(DE) REINIGUNGSVORRICHTUNG MIT EINEM HUBKOLBEN
(EN) CLEANING APPARATUS HAVING A PISTON
(FR) ARRANGEMENT DE NETTOYAGE AVEC UN PISTON ALTERNATIF
Abstract
(DE)
Die Erfindung betrifft eine besondere zur Reinigung von optischen und optoelektronischen Sensoreinrichtungen bei Kraftfahrzeugen optimierte Reinigungsvorrichtung (1) Gehäuse (2), einem in dem Gehäuse (2) druckgesteuert verfahrbaren Hubkolben (3), welcher entlang einer Betätigungsachse (A) aus einer eingefahrenen Ausgangsposition in eine ausgefahrene Reinigungsposition verfahrbar ist, wobei der Hubkolben (3) einen Innenkanal (4) zum Transport eines Reinigungsfluids durch den Hubkolben (3) hindurch zu einer Sprühdüse (5) aufweist. Um eine besonders miniaturisierte, einfach und kostengünstig herstellbare Reinigungsvorrichtung (1) anzubieten, welche eine möglichst exakte und präzise Ausrichtung des Reinigungsstrahls, eine schnelle Funktionsbereitschaft, eine verringerte Nachlaufneigung des Reinigungsfluids, eine verbesserte Anpassbarkeit an unterschiedliche Einbaupositionen ermöglicht wird erfindungsgemäß vorgeschlagen, dass wenigstens die Reinigungsvorrichtung (1) wenigstens ein Führungsmittel (6) zur Verdrehsicherung des Hubkolbens (3) um die Betätigungsachse (A) während seines gesamten Hubes aufweist, welches zumindest bereichsweise im Innenkanal (4) angeordnet ist.
(EN)
The invention relates to a special cleaning apparatus (1), optimized for cleaning optical and optoelectronic sensor devices in motor vehicles, comprising a housing (2) and comprising a piston (3) which is movable in the housing (2) in a pressure-controlled manner and which can travel from a retracted starting position to an extended cleaning position along an actuating axis (A), wherein the piston (3) has an inner channel (4) for transporting a cleaning fluid through the piston (3) to a spray nozzle (5). The aim of the invention is to provide a cleaning apparatus (1) which is particularly miniaturized, simple and cost-effective to produce and which enables as exact and precise an alignment of the cleaning jet as possible, fast functional readiness, reduced tailing tendency of the cleaning fluid and improved adaptability to different installation positions. This aim is achieved, according to the invention, in that at least the cleaning apparatus (1) has at least one guide means (6) for rotation-locking the piston (3) about the actuating axis (A) during the entire stroke thereof, which guide means is arranged in the inner channel (4) at least in regions.
(FR)
L'invention concerne un arrangement de nettoyage (1) notamment optimisé pour le nettoyage de dispositifs capteurs optiques et optoélectroniques dans des véhicules automobiles, comprenant un boîtier (2), un piston alternatif (3) qui peut se déplacer dans le boîtier (2) sous commande de pression et qui peut se déplacer le long d'un axe d'actionnement (A), depuis une position de départ rentrée à une position de nettoyage déployée. Le piston alternatif (3) possède un canal intérieur (4) servant à transporter un liquide de nettoyage à travers le piston alternatif (3) vers une buse de pulvérisation (5). L'invention vise à réaliser un arrangement de nettoyage (1) particulièrement miniaturisé, pouvant être fabriqué de manière simple et peu coûteuse et qui permet un alignement aussi précis et exact que possible du jet de nettoyage, une disponibilité opérationnelle rapide, une tendance réduite à la poursuite de l'écoulement du liquide de nettoyage, une meilleure adaptabilité aux différentes positions de montage, et se caractérise à cet effet en ce qu'au moins l'arrangement de nettoyage (1) possède au moins un moyen de guidage (6) destiné à empêcher une torsion du piston alternatif (3) autour de l'axe d'actionnement (A) pendant la totalité de sa course, ledit moyen de guidage étant disposé au moins par endroits dans le canal intérieur (4).
