To provide a device suitable for a metered delivery of a viscous fluid like an adhesive agent.

This device for of the metered delivery of the viscous fluid is equipped with a pump body (1) with a drill hole (4) for storing two pistons (2, 3) and connecting a first chamber (5) working as a receiving chamber to a second chamber (6) working as a discharging chamber. As a driving mechanism (7), two oscillating arms (17, 18) driven by two cam disks (15, 16) are arranged to drive the two pistons (2, 3) forward and backward. For the metered delivery of the adhesive agent containing silver flakes, the drill hole (4) serves for guiding both pistons (2, 3) and for sealing a pump path.
