This device 14 for distributing a product as a spray, comprises a distributing valve (30) comprising: a valve body (40), defining an inner chamber (52), an actuating rod (42) defining an interior distribution duct (62) that opens outside of the rod (42) via an orifice for entry (64) and via an orifice for exiting (66), with the actuating rod (42) being mobile in the chamber (52) between a distribution position and a blocking position, and a return element (44) of the actuating rod (42) to its blocking position.

The distribution device (14) also comprises a non-return valve (70) arranged inside the actuating rod (42) in order to prevent the circulation of a fluid in the distribution duct (62) from the orifice for the exiting (66) towards the orifice for the entry (64).
