GAS-TURBINE ENGINE HYDRAULIC STARTING DEVICE

摘要

FIELD: mechanical engineering; gas-turbine plants; automatics. ^ SUBSTANCE: proposed device for hydraulic starting of gas-turbine engine includes at least one variable-capacity pump, at least one overflow hydraulic valve and at least one hydraulic motor. At least one hydraulic motor has constant working volume, and summery delivery of pumps of device at any moment of time exceeds flow rate of working liquid consumed by said hydraulic motor by preset valve. Difference between summary delivery of pumps and flow rate of working liquid consumed by hydraulic motor can change within preset limits. ^ EFFECT: simplified design, improved reliability of device. ^ 2 cl
