Devices for cleaning vessels, especially swimming pools, are discussed. The devices may include a non-linear flow path in a gap surrounding an in-line valve (14). This non-linearity permits lengths of concentric pipes (18, 22) forming the gap (G1, G2) to be decreased without sacrificing operational performance of the devices. Valves forming parts of the cleaning devices may be diaphragms but shaped, sized, reinforced, or configured differently than existing valves and may have collapsible segments whose interior shape resembles an ellipse in transverse cross-section. Comolding of diaphragms and pipes may occur, and inner and outer cups may be used to fix relative positions of various components of the devices.

La présente invention a trait à des dispositifs pour le nettoyage d'enceintes, notamment des piscines. Les dispositifs peuvent comporter un chemin d'écoulement non linéaire dans un espace entourant une soupape en ligne. Cette non linéarité permet de réduire les longueurs de conduites concentriques formant l'espace sans sacrifier l'efficacité de fonctionnement des dispositifs. Des soupapes faisant partie des dispositifs de nettoyage peuvent être des diaphragmes mais façonnés, dimensionnés, renforcés, ou conformés différemment des soupapes connues et peuvent comporter des segments repliables dont la forme intérieure ressemble à une ellipse en coupe transversale. Il est possible de réaliser un moulage conjoint des diaphragmes et des conduites, et des coupelles intérieures et extérieures peuvent être utilisées pour fixer la position relative des divers composants des dispositifs.
