Abstract: A fluid-type shock absorber, particularly for doors of electrical household appliances, comprising a shock absorber body, in which a substantially cylindrical chamber is defined that accommodates coaxially a piston provided with a stem that protrudes from at least one axial end of the chamber, the piston divides the chamber into two parts, the piston is accommodated so that it can slide axially within the chamber, moreover at least one duct is provided for connecting the two parts of the chamber in order to allow the transit of a fluid from one part to the other of the chamber for the axial sliding of the piston with respect to the shock absorber body, the connecting duct is defined in the piston and has a calibrated portion thereof that is defined on a first end face of the piston, elements are provided for varying the passage section of the connecting duct available for the fluid.
