Title (EN) CLAMPING STATOR PARTS IN LINEAR COMPRESSORS
(FR) COMPRESSEUR LINEAIRE
Abstract:
(EN) A linear compressor includes a cylinder part with a cylinder bore. A piston is disposed in the bore and slidable therein. A main spring connects the cylinder part to the piston. A connecting member connects between the main spring and the piston. The connecting member passes through the air gap of a stator of a linear electric motor. At least one armature pole of the motor is located along the connecting member. The stator comprises a plurality stator parts opposed across the air gap. The cylinder part includes a tapered clamp for each stator part. The tapered clamp widens outward from the air gap. Each stator part has a matching taper and is engaged in the tapered clamp.
(FR) L'invention porte sur un compresseur linéaire comportant un cylindre alésé à l'intérieur duquel coulisse un piston relié par un ressort principal au cylindre par l'intermédiaire d'un élément de connexion traversant l'entrefer du stator d'un moteur électrique linéaire. L'un au moins des pôles de l'armature du moteur est situé le long de l'élément de connexion. Le stator comprend plusieurs parties opposées situées de part et d'autre de l'entrefer. Le cylindre comporte pour chacune des parties du stator une mâchoire conique s'ouvrant vers l'extérieur depuis l'entrefer, à l'intérieur de laquelle s'engage une partie conique correspondante du stator.
