Abstract
(DE)
Die Erfindung betrifft ein Expansionsventil (10), zur Steuerung eines Fluidstroms, mit einem Ventilmittelgehäuse (12) und wenigstens einem im Ventilmittelgehäuse (12) bewegbar angeordneten Ventilmittel (16) und einem Aktuatorgehäuse (14) in welchem der elektrischen Antrieb des Expansionsventils (10) angeordnet ist, wobei das Ventilmittelgehäuse (12) im Wesentlichen zumindest teilweise aus einem Metall, insbesondere aus Aluminium ausgebildet ist und wobei das Aktuatorgehäuse (14) im Wesentlichen zumindest teilweise aus Kunststoff ausgebildet ist und wobei das Aktuatorgehäuse (14) am Ventilmittelgehäuse (12) mittels zumindest einem Verbindungselement (40) befestigt ist Es wird vorgeschlagen, dass das Verbindungselement (40) zumindest teilweise als Rastelement und/oder Clipselement ausgebildet ist.
(EN)
The invention relates to an expansion valve (10), for controlling a fluid flow, having a valve means housing (12) and at least one valve means (16), which is movably arranged in a valve means housing (12), and an actuator housing (14), in which the electrical drive of the expansion valve (10) is arranged, wherein the valve means housing (12) is formed substantially at least in part of a metal, in particular of aluminum, and wherein the actuator housing (14) is formed substantially at least in part of plastic and wherein the actuator housing (14) is secured on the valve means housing (12) by means of at least one connection element (40). According to the invention, the connection element (40) is formed at least in part as a latching element and/or clip element.
(FR)
L'invention concerne une vanne de détente (10) pour la commande d'un flux de fluide, comprenant un boîtier central de vanne (12) et au moins un moyen de vanne (16) disposé de manière mobile dans le boîtier central de vanne (12) et un boîtier d'actionneur (14) dans lequel est disposé l'entraînement électrique de la vanne de détente (10). Le boîtier central de vanne (12) est principalement au moins partiellement constitué d'un métal, notamment d'aluminium, le boîtier d'actionneur (14) est principalement constitué au moins partiellement de matière plastique et le boîtier d'actionneur (14) est fixé au boîtier central de vanne (12) au moyen d'au moins un élément de liaison (40). Selon l'invention, l'élément de liaison (40) est réalisé au moins partiellement sous la forme d'un élément d'encliquetage et/ou d'un élément d'enclipsage.
