Abstract
Abstract AN AUTOCLAVE DEVICE PROVIDED WITH DIFFERENT PRESSURE CHAMBERS BETWEEN WHICH GOODS TO BE TREATED CAN BE TRANSFERRED IN A PREETERMINED DIRECTION OF FLOW WITHOUT THE NECESSITY OF EQUALIZING THE PRESSURE DURING THE TREATMENT IN ONE CHAMBER TO AMBIENT ATMOSPHERIC PRESSURE BEFORE TRASFERRING THE GOODS TO A NEXT CHAMBER. THIS NEW DEVICE ENABLES AN AUTOCLAVE PROCESS TO BE PERFORMED CONTINUOUSLY AND EVEN AUTOMATICALLY WITH CONSIDERABLE SAVINGS IN STEAM CONSUMPTION.
