Abstract

A ball two-stage generator of pressure pulses includes ball shutoff element of second stage pressed by pusher that is fixed with spring to seat of pressure line of hydraulic system that is connected to cavity in which ball shutoff element of automated throttle is placed, this Is pressed by spring to pusher that is in tight contact with ball shutoff element of the first stage pressed to the seat with controlled spring. Between the pressure cavity and cavity of pusher of ball shutoff element of the first stage automated throttle is placed, this is loaded with spring with which through pusher ball shutoff element of automated throttle is pressed to ball shutoff element of the first stage.
