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.
Claims10
A metering device comprising:
- a main body including a continuous bore,
- an adjusting socket disposed in said bore,
- a movable stopping pin disposed partially in said socket,
- a movable metering piston disposed partially in said socket opposite said stopping pin, said main body, said stopping pin, and said metering piston forming an interchangeable module,
- a movable metering chamber of variable volume bounded by the inside wall of said socket, said stopping pin, and said piston,
- at least one admission duct and one ejection duct, each connected independently to said chamber for allowing admission thereto and expulsion therefrom of the substance to be metered,
- at least one control unit for controlling displacement of said piston,
- actuating means for displacing said pin and said stopping piston simultaneously relative to said main body, and
- assembling means detachably securing said interchangeable module to said actuating means.
