VESSEL HYDRAULIC STEERING GEAR

摘要

PURPOSE:To improve the steering performance by providing an electric hydraulic servo valve controlling a pilot hydraulic pressure with an electric signal obtained by correcting a rudder angle command signal and a servo cylinder controlling the inclination angle of a main hydraulic pump with the hydraulic pressure from said valve. CONSTITUTION:An electric hydraulic servo valve 8 controlling a pilot hydraulic pressure with an electric signal obtained by correcting a rudder angle command signal with an actual rudder angle feedback signal and the inclination angle feedback signal of a main hydraulic pump 4 and a servo cylinder 11 controlling the inclination angle phi of the main hydraulic pump 4 with the hydraulic pressure from said valve are provided so as to perform the steering through them. Thereby, the steering with the excellent responsiveness and rudder angle precision can be performed.
