Assembly, apparatus and method for dispensing a fluid product

Abstract

An assembly for dispensing a fluid product comprises a housing (44) having a dispensing opening (40) and a mounting (42) for a container (12) for containing the fluid product, a pumping device (45), a diverting element (53) rotatable about an axis of rotation (R), the diverting element (53) being provided with a first channel (A) and a second channel (B), the first channel (A) and the second channel (B) are in fluid communication with each other and each have an open end (66) arranged radially with respect to the rotation axis (R) on an outer peripheral surface (65) of the rotatable diverting element (53). The assembly further comprises a suction conduit (49) connected to an inlet of a pumping device (45) for drawing a fluid product from said container (12) mounted on the mount (42), a delivery conduit (50) fluidly connecting an outlet of the pumping device (45) with said rotatable diverting element (53), and a recirculation conduit (52) fluidly connecting the delivery conduit (50) and said rotatable diverting element (53). A recirculation conduit (52) is arranged downstream of the diverting element (53) for returning the fluid product to the container (12). The rotatable diverting element (53) has at least one recirculation position (O) in which the open end (66) of one of the channels faces the open end of the delivery conduit (50) for fluid communication with the delivery conduit (50) and at least one delivery position (I) in which the open end (66) of the other channel faces the recirculation conduit (52) for fluid communication with the recirculation conduit (52) for fluid communication with the delivery conduit (50). And a delivery position (I) in which the open end (66) of one of the channels faces the open end of the delivery conduit (50) for fluid communication with the delivery conduit (50) and the open end (66) of the other channel faces the dispensing opening (40) for dispensing the fluid product.

Description

technical field [0001] The present invention concerns assemblies and methods for dispensing fluid products, particularly colored fluid products such as paints, pigments, coating compositions, etc., as well as dispensing machines comprising one or more such assemblies and their use, for example, in retrofit Or prepare user-defined formulations in repair applications (e.g. paint formulations). Background technique [0002] Assemblies for dispensing fluid products are well known in the art and are typically associated with automatic dispensers for dispensing fluid products. Such a machine may include multiple components for dispensing the fluid product, each configured to deliver paint having a different color, shade or lightness variation. [0003] In dispensing machines known in the art, a delivery station is provided. The receiving container (receptacle) is placed in the delivery station, one or more products are delivered to the receiving container, the one or more produc...

Problems solved by technology

[0011] Another disadvantage of the aforementioned assemblies known in the art is that they are bulky

This means that the dispensing machine associated with the above components needs a larger internal volume to accommodate these components, so the dispensing machine will in turn be larger
