摘要 <p>After a quenching operation, all or part of the gas from the quenching cell (V1) passes to an intermediate storage tank (V3) by partial or complete pressure balance between the two volumes. The gas in the storage tank is then transferred through a compression or surpression group comprising one or more compressors/supressors in parallel (C1, C2..) to a balance capacity (V2) feeding the cell : Method of quenching in gas, where a quenching cell (V1) designed to receive objects to be quenched in a gas is connected to means of putting the cell under pressure. The means of putting the cell under pressure comprise a balance capacity (V2) containing the quenching gas. Part of the cell content is vented to atmosphere if necessary. The transfer from the intermediate storage tank to the balance capacity takes place while the quenching cell is immobile or while the parts for quenching are transferred. An inflatable capacity (V4) is placed to receive gas from the cell through a vacuum pump (P1). This is then disconnected from the vacuum pump and connected to the compression/surpression unit to which the gas is discharged.</p>
