HYDRAULIC ROTARY MACHINE Russian patent published in 1994 - IPC

FIELD: machine tool manufacture. SUBSTANCE: machine has a frame with a rotary working chamber in the form of two conical bowls mounted inside and connected by large bases. A swirler with equidistant circumferential acceleration and braking nozzles connected to an air distributor is located on the chamber bottom. The machine also has a part washing system. The working chamber has a cone with height no less than 2/3 of the height of the lower bowl, the cone is located in the center of the bowl. The cone has additional horizontally equidistant circumferential nozzles at the height of no more than 0.2 of the height of the lower bowl at an angle of 30° to the cone radius, the nozzles are connected to the cavity of acceleration nozzles by an air channel with an orifice which reduces pressure by a factor of 1.5-2.0. The machine also has a cycle automatization system, the cycle is set through a time relay mounted on the machine. EFFECT: improved intensity and uniformity of working and cycle automatization . 2 cl, 5 dwg
