Device for delivering and injecting liquid

摘要

In a device for delivering and injecting liquid, especially softened water, there are arranged, in a casing, cylindrical plunger trajectories in a circular manner, which run through the casing cover, reservoir and bearings. The plungers, enclosed by pressure springs, in the trajectories are moved up and down via discs, disc rod and rollers by a cam sitting on the shaft and as a result form cylindrical chambers which on the one hand diminish and on the other hand increase in size, after the shaft with the cam has been set into rotary motion and the plunger trajectories have been filled with softened water from the reservoir via the overflow ducts.
