駆動システム。 The discharge oil of the hydraulic pump is supplied to the hydraulic cylinder for driving the stabilizer fin through the check valve and electro-hydraulic servo valve inserted in the discharge oil pipe, and the return oil from the hydraulic cylinder is supplied to the hydraulic cylinder for driving the stabilizer fin through the electro-hydraulic servo valve and the return oil pipe. In a hydraulic system in which the discharge oil pipe was bypassed to the return oil pipe through the main relief valve, the hydraulic pump attached to the discharge oil pipe was started without load for a short period of time. The unloading solenoid valve, which is later switched to load start, the accumulator inserted into the above-mentioned discharge oil pipe, the pilot operate check valve inserted into the pipe between the electro-hydraulic servo valve and the hydraulic cylinder, and the main relief valve. What is claimed is: 1. A fin stabilizer drive system comprising: a means for maintaining relief pressure within a set pressure range;
