PROBLEM TO BE SOLVED: To make a hydraulic system running from a hydraulic oil pump which is a hydraulic source to each hydraulic device as simple and short as possible, in a reduction reverse gear.SOLUTION: There are provided a forward backward switching mechanism for switching a rotational power of a main engine 7 mounted on a ship into an output of forward, neutral or backward, an output shaft 13 which transmits an output from the forward backward switching mechanism to a propeller, and a neutral brake 31 for braking the output shaft 13 at the neutral of the forward backward switching mechanism. The output shaft 13 is rotatably pivoted at a lower part of a housing 9 having the forward backward switching mechanism. A forward backward switching valve 25 for controlling switching operation of the forward backward switching mechanism and a brake switching valve 30 for controlling operation of the neutral brake 31 are unitized as a switching valve unit 46.SELECTED DRAWING: Figure 2
【課題】減速逆転機において、油圧源である作動油ポンプから各油圧装置に至る油圧系統をできるだけ簡単且つ短くできるようにする。【解決手段】船舶に搭載した主機関7の回転動力を前進、中立又は後進の出力に切り換える前後進切換機構と、前後進切換機構からの出力をプロペラに伝達する出力軸13と、前後進切換機構の中立時に出力軸13を制動させる中立ブレーキ31とを備える。前後進切換機構を有するハウジング9の下部に出力軸13を回転可能に軸支する。前後進切換機構の切換作動を制御する前後進切換弁25と、中立ブレーキ31の作動を制御するブレーキ切換弁30とを、切換弁ユニット46としてユニット化する。【選択図】図2
