Beschreibung
Zusammenfassung:	A device for delivering a measured charge of a flowable powder comprising a storage container, a vertical piston rod and a buffer vessel, the rod being provided with a constriction which reaches into the storage container when the piston rod is at the upper end of its stroke, and reaches into the buffer vessel when the piston rod is at the lower end of its stroke. In the latter position the piston rod fits tightly in a first channel which is in connection with a second channel which has a clearing rod. At one end of its stroke the clearing rod occupies the second channel and at the opposite end of its stroke establishes a communication between the first channel and the open end of the second channel.
