FIELD: mechanics, mining.
SUBSTANCE: proposed hydraulic vibrator for wells comprises a pump, feeding pipe and metal cup with orifices enclosed with an elastic membrane to form a space. The pump communicates with the said space via a cutoff valve. The aforesaid orifices are made on the cup side surface with their total area smaller than the feeding ripe flow area the said membrane is tightly attached to the feeding pipe.
EFFECT: simpler and smaller device, smaller vibrator, expanded possibilities of vibration control.
