The present invention is a cartridge underbody attachment for a single control faucet. The attachment generally comprises a valve body having a cartridge housing that seats within a spout body. The spout body comprises a wide central portion opening into a sideways extending cylindrical port having a notch formed therein. The cartridge housing is inserted through the open bottom of the spout body. The cartridge housing generally comprises a cover having defined apertures, and a pentagonal housing attached to the rear surface of the cover. Valve hoses soldered within the pentagonal housing are in fluid communication with the apertures. A pin on the cover locks into the notch in the spout body to securely retain the cartridge housing, such that the housing can form an off-axis connection with the valve cartridge. A cartridge support housing and retainer nut further secure the valve body and cartridge within the spout body.

La présente invention concerne un accessoire de dessous de cartouche destiné à un robinet à poignée unique. De façon générale, l'accessoire comprend un corps de vanne pourvu d'un logement de cartouche qui se place à l'intérieur d'un corps de bec. Le corps de bec comprend une large partie centrale s'ouvrant en un orifice cylindrique s'étendant latéralement, ayant une encoche formée dans celui-ci. Le logement de cartouche est inséré par le fond ouvert du corps de bec. De façon générale, le logement de cartouche comprend un couvercle présentant des ouvertures définies, ainsi qu'un logement pentagonal fixé à la surface arrière du couvercle. Des flexibles de vanne soudés à l'intérieur du logement pentagonal sont en communication fluidique avec les ouvertures. Sur le couvercle, une broche se verrouille dans l'encoche située dans le corps de bec afin de maintenir de façon sûre le logement de cartouche, de sorte que le logement peut former un raccord excentré avec la cartouche de vanne. De plus, un logement de support de cartouche et un écrou de serrage fixent le corps de vanne et la cartouche à l'intérieur du corps de bec.
