Abstract

A device for dosing fluid or pasty synthetic material, to be used in connection with a walled mixing chamber, the wall being provided with conduit means, and valve means disposed in the conduit means and including valve seat means in the chamber wall. Valve actuating means operate the valve means, and an impulse actuator actuates the valve actuating means and thereby the valve means in accordance with a predetermined time schedule.

Claims

2. In a device, as claimed in claim 1, said valve means comprising a plurality of valves, said valve actuating means including a plurality of valve actuators each in driving connection with a valve, said impulse actuator being operable to operate all of said valve actuators and hence said valves in timed relationship.

3. In a device, as claimed in claim 2, said impulse actuator actuating all of said valve actuators and hence all of said valves synchronously.
