Fluid dispenser, characterized essentially by being constituted by a rigid metallic tubular body in envelope functions, with a lateral inlet for a control fluid, with its provided mouthpieces of sockets forming internal spike extensions between which a tubular component is arranged. Elastic of an inert and resistant material, the inlet sleeve having a free ball valve, located inside a tubular sealing element, while the outlet sleeve has a check valve, resulting in the effect of compression dosing and elastic expansion, motivated by the pressure of the control fluid, of the internal tubular component, occupied by the controlled fluid.
