Title
(DE) EXPANSIONSVENTIL
(EN) EXPANSION VALVE
(FR) VANNE DE DÉTENTE
Abstract
(DE)
Die Erfindung betrifft ein Expansionsventil (1), - mit einem Gehäuse (4), einem Sensor (29), einem Schrittmotor (6) oder einem BLDC-Motor, einem Ventilsitz (7) sowie einem damit zusammenwirkenden Ventilkörper (8), - wobei der Schrittmotor (6) oder der BLDC-Motor einen Rotor (10) einen den Rotor (10) umgebenden Stator aufweist, - wobei der Rotor (10) eine Welle (13) sowie einen drehfest damit verbundenen Permanentmagnetkörper (14) aufweist, - wobei der Sensor (29) zur Erfassung einer axialen Position und/oder eines Drehwinkels des Permanentmagnetkörpers (14) ausgebildet ist. Hierdurch kann ein bauraumoptimiertes und zugleich kostengünstiges Expansionsventil (1) geschaffen werden.
(EN)
The invention relates to an expansion valve (1), - having a housing (4), a sensor (29), a stepping motor (6) or a BLDC motor, a valve seat (7) and a valve body (8) interacting therewith, - wherein the stepping motor (6) or the BLDC motor has a rotor (10) and a stator enclosing the rotor (10), - wherein the rotor (10) has a shaft (13) and a permanent magnet body (14) fixed thereto for conjoint rotation, - wherein the sensor (29) is designed for acquiring an axial position and/or an angle of rotation of the permanent magnet body (14). An expansion valve (1) with optimized installation space requirement while simultaneously being inexpensive can be created in this way.
(FR)
La présente invention concerne une vanne de détente (1) pourvue de : - un boîtier (4), un capteur (29), un moteur pas à pas (6) ou un moteur BLDC, un siège de vanne (7) ainsi qu’un corps de vanne (8) coopérant avec ledit siège. Le moteur pas à pas (6) ou le moteur BLDC comprend un rotor (10) et un stator entourant le rotor (10), le rotor (10) comprenant un arbre (13) ainsi qu’un corps d’aimant permanent (14) relié solidaire en rotation à l’arbre. Le capteur (29) est conçu pour détecter une position axiale et/ou un angle de rotation du corps d’aimant permanent (14). On peut ainsi obtenir une vanne de détente (1) optimisée quant à l’encombrement et en même temps économique.
