Abstract

Ammortizzatore per macchine lavatrici, in particolare macchine lavabiancheria o macchine combinate per il lavaggio e l'asciugatura della biancheria, atto a smorzare le oscillazioni del gruppo vasca-cesto prodotte nel corso di svolgimento dei cicli di lavaggio. Ammortizzatore comprendente un involucro tubolare metallico (4) ed uno stelo (9) scorrevole alternativamente nell'interno dell'involucro (4), i quali sono collegati con la loro estremità libera rispettivamente con il basamento inferiore del mobile e con la parte inferiore della vasca di lavaggio della macchina. Tale stelo (9) è provvisto di una pluralità di elementi frenanti anulari (12) in materiale antifrizione, agenti per attrito contro la superficie interna dell'involucro tubolare (4) per determinare lo smorzamento delle oscillazioni, elementi il cui foro passante centrale (14) ha un diametro che è maggiore del diametro esterno dello stelo (9), sul quale ogni elemento frenante (12) viene applicato, di un valore di luce X.In questo modo, vengono eliminate le interferenze tra gli elementi frenanti e lo stelo, impedendo la deformazione o la rottura di tali elementi nel montaggio e assicurando frenature costanti ed efficaci.Shock absorber for washing machines, in particular washing machines or combined machines for washing and drying laundry, designed to dampen the oscillations of the tub-basket unit produced during the course of washing cycles. Shock absorber comprising a tubular metal casing (4) and a stem (9) sliding alternately inside the casing (4), which are connected with their free end respectively with the lower base of the cabinet and with the lower part of the tub machine wash. This stem (9) is provided with a plurality of annular braking elements (12) in antifriction material, acting by friction against the internal surface of the tubular casing (4) to determine the damping of the oscillations, elements whose central through hole (14 ) has a diameter that is greater than the external diameter of the stem (9), on which each braking element (12) is applied, by a light value X. In this way, interference between the braking elements and the stem is eliminated, preventing deformation or breakage of these elements during assembly and ensuring constant and effective braking.
