In accordance with a method of discharging and applying a flowable medium under pressure, a charge element, and a discharge element is provided. The discharge element has a storage chamber arranged for receiving the flowable medium and provided with an outlet valve, and a gas chamber arranged for accommodating a pressure gas medium and separated from the storage chamber by a displaceable member allowing to vary the volumes of the chambers. Flowable medium is fed from the charge element element into the storage chamber of the discharge element so that the displaceable member displaces in the direction toward the gas chamber, the volume of the storage chamber increases, the pressure gas medium in the gas chamber is compressed and thereby the flowable medium is stored in the storage chamber under pressure. The flowable medium is discharged from the storage chamber of the discharge element through the outlet valve by reducing the volume of the storage chamber and increasing the volume of the discharge element with displacement of the displaceable member in the opposite direction and simultaneous expansion of the gas medium into the gas chamber of the discharge element.

A method of discharging and applying flowable medium under pressure, comprising the steps of providing a charge element, and a discharge element having an outlet valve, a storage chamber of a predetermined volume and arranged for receiving the flowable medium, and a gas chamber arranged for accommodating a pressure gas medium and separated from the storage chamber by a displaceable member allowing to vary the volumes of said chambers; feeding the flowable medium from the charge element into the storage chamber of the discharge element, so that the displaceable member displaces in the direction toward the gas chamber, the volume of the storage chamber increases, the pressure gas medium in the gas chamber is compressed and thereby the flowable medium is stored in the storage chamber under pressure; discharging the flowable medium from the storage chamber of the discharge element through the outlet valve by reducing the volume of the storage chamber and increasing the volume of the gas chamber of the discharge element with displacement of the displaceable member in the opposite direction and simultaneous expansion of the gas medium in the gas chamber of the discharge element, said feeding and discharging steps being permanently repeated; and providing a metering element for adjusting the quantity of the flowable medium fed from the charge element into the storage chamber so that said quantity is limited to said predetermined volume.
