Abstract: front page image
(EN)A hermetic compressor of the present invention includes a thrust-ball bearing having balls (168) disposed in a holder (170) in a manner that the balls (168) roll along at least two tracks (182a, 182b, 184a and 184b). The invented structure decreases the number of balls (168) that roll along each of the tracks (182a, 182b, 184a and 184b), and reduces a frequency of sliding between the balls (168) and the tracks (182a, 182b, 184a and184b), thereby alleviating wear of the tracks.
(FR)Le compresseur hermétique selon la présente invention comprend une butée à billes ayant des billes (168) disposées dans un support (170) de manière à ce que les billes (168) roulent le long d'au moins deux pistes (182a, 182b, 184a et 184b). La structure de l'invention réduit le nombre de billes (168) qui roulent le long de chacune des pistes (182a, 182b, 184a et 184b), et elle réduit une fréquence de glissement entre les billes (168) et les pistes (182a, 182b, 184a et 184b), réduisant ainsi l'usure des pistes.
