Abstract
PURPOSE: To ensure low cost and high efficiency, by turning an oil pump for supplementing a circulation closed circuit by means of an oil pressure motor shaft, and by arranging an oil pressure pump control circuit by connecting a pressure accumulator to a conduit to a servo-valve from a conduit at the low pressure side.
CONSTITUTION: When a prime mover 2 is driven to turn an oil pressure pump 1 and a power source of a torque motor 21 is switched ON to apply a fixed input. a servo-valve 18 is operated, the compressed oil of a pressure accumulator 27 enters a servo-cylinder 4 or 5 through a throttle valve 28, a swash plate 3 is displaced to discharge a fixed quantity of flow rate from the oil pressure pump 1, and oil is fed to an oil pressure motor 9 from a conduit 7 at the high pressure side to rotate an underwater pump 11 and an oil pump 13 for supplement. If providing the torque motor 21 with a command when chainging the discharge quantity of the underwater pump 11 during operation, the angle of the swash plate 3 changes in a quantity corresponding to the command, and the discharge quantity of the oil pressure pump 1 varies, thus changing the number of the revolution of the oil pressure motor 9 and the underwater pump 11. Consequently, a pump that ensures low cost and high efficiency can be obtained
