Published date

Specifica le dimensioni e le relative tolleranze degli alloggiamenti sul pistone per le guarnizioni in plastica, attivate da anelli elastomerici, di comune impiego nei casi di moto alterno. Non si occupa dei dettagli relativi alla conformazione delle guarnizioni, poiché ogni costruttore adotta soluzioni diverse. La conformazione ed il materiale delle guarnizioni e degli eventuali anelli antiestrusione dipendono dai campi di temperatura e di pressione. Riguarda le sole caratteristiche dimensionali, e non quelle funzionali, dei componenti a cui si riferisce. Appendice A: Bibliografia (ISO 468 e ISO 4394/1).
