Improved shock absorber for hydraulic pumps, especially for piston or diaphragm pumps, essentially characterized in that it is constituted by a cylindrical chamber in which it has a piston displaced towards one end of said chamber by the effect of an expansion spring seated against the opposite end, of the same, while the end of the chamber facing the plunger is provided with a coupling coupling to a branch of the outlet conduit of the pump, while the opposite end of the chamber has a free exit port; so that said piston recedes with the hydraulic pressure increases caused by the impulses of the piston or membrane of the pump providing a uniform outlet pressure.
