Abstract

The device has a drive shaft (12) and a differential piston pump. The differential piston pump is driven by the drive shaft and a valve control unit (18) is arranged for operating an inlet and outlet valve arrangement. A tappet is arranged on the drive shaft for a differential piston (K) and the valve control unit. The differential piston and the valve control unit are coupled with a pressure coupling directly at the tappet. An independent claim is also included for a differential piston pump for a fluid.
