Zusammenfassung:A pressure fluid impulse converter for transforming primary pressure fluid impulses of a higher frequency into secondary pressure fluid impulses of a lower frequency, comprising a hydraulically actuated activating means arranged to cause a valve in a pressure fluid circuit to shift from a closed to an opened position and a positive displacement pump which is actuated by the primary pressure fluid impulses and arranged to feed motive hydraulic fluid to said activating means. The latter is thereby stepwise displaced from a rest position to a valve activating position.
