PULSE GENERATOR

摘要

Disclosed is a pulse generator in which to two-stage pulsator valve a hydro-system is connected that controls parameters of its operation. By means of that one pulse generator can operate in three modes of pulsation:1. High frequency and small amplitude of pulses (smaller spool);2. Low frequency and high amplitude of pulses (larger spool);3. Superposition of low frequency and high amplitude pulse to pulses with high frequency and small amplitude (both spools).
