Abstract

L'invention concerne une soupape de détente électronique et un appareil de réfrigération. La soupape de détente électronique comprend un siège de soupape (100) et au moins un raccord (300). Un orifice (110) est formé à une extrémité du siège de soupape (100) ; une chambre de soupape (120) en communication avec l'orifice (110) est formée dans le siège de soupape (100) ; et le siège de soupape (100) est pourvu d'au moins un orifice de montage (130), l'orifice de montage (130) étant en communication avec la chambre de soupape (120). Le connecteur (300) est disposé au niveau de l'orifice de montage (130), le connecteur (300) étant pourvu d'un canal d'adaptateur (310a), et une extrémité du canal d'adaptateur (310a) étant en communication avec l'orifice de montage (130). La soupape de détente réduit la quantité de matériaux de siège de soupape, et permet d'obtenir un poids faible.
