Title
(EN) FLUID DELIVERY ASSEMBLY FOR A SPRAYING APPARATUS
(FR) ENSEMBLE DE DISTRIBUTION DE FLUIDE POUR APPAREIL DE PULVÉRISATION
Abstract
(EN)
The present invention relates to a fluid delivery assembly for a spraying apparatus. The assembly comprises an outer cup, a lid having a fluid outlet adapted to couple the lid to the spraying apparatus, and a liner for holding paint. The fluid delivery assembly comprises an interlocking keyed geometry adapted to prevent rotation of at least one of the lid and the liner with respect to the cup. The interlocking keyed geometry comprises at least one of (a) at least one protrusion of the cup extending into at least one recess of the lid, and (b) at least one protrusion of the lid extending into at least one recess of the cup, wherein the liner is trapped between the protrusion and the recess. The invention also relates to liners for such fluid delivery assemblies, which may be provided as a set of liners having different inners volumes.

La présente invention concerne un ensemble de distribution de fluide pour un appareil de pulvérisation. L'ensemble comprend une coupelle externe, un couvercle ayant une sortie de fluide conçue pour accoupler le couvercle à l'appareil de pulvérisation, et un revêtement pour contenir de la peinture. L'ensemble de distribution de fluide présente une géométrie clavetée de verrouillage conçue pour empêcher la rotation du couvercle et/ou du revêtement par rapport à la coupelle. La géométrie clavetée de verrouillage comprend (a) une saillie de la coupelle s'étendant dans au moins un évidement du couvercle et/ou (b) au moins une saillie du couvercle s'étendant dans au moins un évidement de la coupelle, le revêtement étant piégé entre la saillie et l'évidement. La présente invention concerne également des revêtements pour de tels ensembles de distribution de fluide, qui peuvent être fournis sous la forme d'un ensemble de revêtements ayant différents volumes intérieurs.
