Claims (1)
用主油圧ポンプ及び停止ポンプ逆転防止升、バイパス弁
駆動用補助ポンプを有する常用と完全予備の２系統の油
圧舵取回路を具えたものにおいて、駆動側の補助油圧ポ
ンプの油圧を利用して両系統の停止ポンプ逆転防止弁及
びラム遊動のためのバイパス弁の開閉をそれぞれ自動的
に行なうとともに、駆動側の停止ポンプ逆転防止弁の開
、動作を停止側のバイパス弁の関動作よりも若干遅らせ
るようにしたことを特徴とする舶用油圧舵取装置。In order to move the same rudder shaft at once, it is equipped with two hydraulic steering circuits, one for regular use and one for complete backup, each having a main hydraulic pump for driving a hydraulic cylinder, a stop pump for preventing reverse rotation, and an auxiliary pump for driving a bypass valve. The hydraulic pressure of the auxiliary hydraulic pump on the drive side is used to automatically open and close the stop pump reverse prevention valves in both systems and the bypass valve for ram drift, and also to open and operate the stop pump reverse prevention valve on the drive side. A hydraulic steering device for a marine vessel, characterized in that the timing is slightly delayed compared to the engagement operation of a bypass valve on the stop side.
