1. An assembly for dispensing fluid products, comprising:
a housing having a dispense opening and comprising a mount for a container that contains the fluid product,
pumping means,
a valve arrangement comprising a diverting element rotatable around a rotation axis provided with a first channel and a second channel, which are in fluid communication with one another and each have an open end arranged radially with respect to the rotation axis on a peripheral surface of the rotatable diverting element,
a suction conduit connected to an inlet of the pumping means for withdrawing fluid product from said container installed on the mount,
a delivery conduit fluidly connecting an outlet of the pumping means and said rotatable diverting element,
a recirculation conduit fluidly connecting the diverting element to the container for returning fluid product to it,
wherein the rotatable diverting element has at least one recirculation position in which the open end of one of the channels faces the open end of the delivery conduit to be in fluid communication with the delivery conduit and the open end of the other channel faces the recirculation conduit to be in fluid communication with the recirculation conduit so as to recirculate the fluid product to the container and at least one delivery position, in which the open end of one of the channels faces an open end of the delivery conduit to be in fluid communication with the delivery conduit, and the open end of the other channel faces the dispense opening for dispensing the fluid product.
