ABSTRACT:
The metering device for supplying precisely measured amounts of any viscous or pasty substance comprises a main body (10) in which there is disposed an adjusting socket (12). A stopping pin (13), and a metering piston (17) are disposed opposite one another in the socket, thus bounding a movable metering chamber (4). The main body also contains an admission duct (14) and an ejection duct (15). By means of at least one control unit (31), the metering piston can be displaced, and actuating means (20) permit the stopping pin and the piston to be displaced simultaneously relative to the main body in order to free the access either to the admission duct or to the ejection duct. The main body, the stopping pin, and the metering piston constitute an interchangeable module.
