The distributor has a reservoir which holds a cartridge (3) contg. the product (6). A cylindrical piston (4) communicates with the interior of the cartridge and has a cylinder (14) round it. A valve (26,30), between the cylinder and the piston, allows the product to flow into the cylinder. An opening (33) in the cylinder's lower end has a valve (35,36), through which the product is distributed. A lever (20) moves the piston opens the valves to distribute the product or fill the cylinder. The valves have two radial walls (26,35) whose openings are closed by axially mobile discs (30,36) moved by springs (31,37).
