FIELD: process engineering.

SUBSTANCE: invention relates to vibration equipment and may be used as generator of mechanical vibrations (for example, in wood working). Hydraulic vibrator comprises housing to accommodate distributor made up of shaft with mutually perpendicular bores and working fluid feed channels. In compliance with this invention, said distributor has four mutually perpendicular bores. Vibrator housing has four channels to allow working fluid feed on hydraulic cylinder rod and piston chambers for rod reciprocation at independent control of distributor rpm.
