Abstract

Metodo ed apparecchiatura per proteggere guarnizioni di alta pressione distanziate in una camera di alta pressione da danno determinato dal mantenere alta pressione tra le guarnizioni dopo che è stata tolta l'alta pressione nella camera. Una valvola di ritegno ad una via è accoppiata alla zona tra le guarnizioni e l'interno della camera di alta pressione per scaricare automaticamente la zona tra le guarnizioni soltanto quando l'alta pressione nella camera è stata rilasciato o tolta.
