Title:
HYDRAULIC CABLE ENGINE
Document Type and Number:
Japanese Patent JPS60132102
Kind Code:
A
Abstract:
PURPOSE:To increase the speed at cable laying by a structure wherein a command dispatcher is provided in a control unit and a bypath, in which a control valve acting on and off by the command sent from the command dispatcher is interposed, is provided between a high pressure oil pipe line and a low pressure pipe line. CONSTITUTION:A command dispatcher 14 is provided in a control unit consisting of a command section 1, a detector 2, a control circuit 3 and a servo mechanism 4. In addition, a bypath, in which a binary control valve 15 acting on and off by the command sent from the command dispatcher 14 is interposed, is provided between a high pressure oil pipe line 12 and a low pressure oil pipe line 13. Thus, the rate of flow fed to a hydraulic motor 10 is made to be several times the maximum rate of flow delivered from a pump 6, resulting in enabling to increase the cable laying speed. Furthermore, because the pump 6 is operated at the efficiency of about 100% at all times, resulting in enabling to efficiently obtain regenerative electric power.
