PROBLEM TO BE SOLVED: To provide a rotary vane type helm machine of a marine vessel which can supply high-pressure hydraulic oil into a pressure chamber and is easy to machine and easy to maintain.SOLUTION: An inner race 1 is rotatably incorporated by an outer race 2, which are embraced by an outer cylinder 3 and a circular bottom plate 4. A sausage-shaped empty annulus ring 10 is formed in a mutually facing part of the inner race 1 and the outer race 2, and this empty annulus ring 10 is loaded with the arrangement of two (or three) pairs of rotary vanes and that of rotary vanes of the same number as those to configure a pressure chamber 16 with four (or six) partitions, where the sausage-shaped empty annulus ring 10 is profiled with no cut to keep rotary vanes and fixed vanes independent with two continuous strips of horse-shoe-shaped sealant embedded by winding in a main material along this empty annulus ring 10, and to make a slide face of the sealant come in pressure-welding with the inner race 1 and the outer race 2 by feeding hydraulic oil out of the pressure chamber 16 into a sealant inner space. The rotary vane and the fixed vane are key-coupled with the inner race 1 and the outer race 2, respectively.SELECTED DRAWING: Figure 1
【課題】圧力室へ高圧の作動油を供給することができ、機械加工が容易で、メンテナンスの容易な構造の船舶のロータリーベーン式舵取機を提供する。【解決手段】内輪1を、外輪2で回動自在に内抱し、これ等を外筒3と円形底板4とで抱被する。内輪1と外輪2との相対部にソーセージ状空円環10を形成し、この空円環10に、2(又は3)組の回転翼と、これと同数の固定翼を配装して、4(又は6)区画の圧力室16を構成する。ここで、ソーセージ状空円環10は切れ目の無い輪郭のものとし、回転翼・固定翼は、この空円環10に沿う主材に、連続した2条の馬蹄形シール材を巻埋設した独立体とし、かつシール材内スペースに圧力室16から作動油を送り込んで、シール材の摺動面を内輪1・外輪2に圧接するようにする。回転翼は内輪1にキーで、固定翼は外輪2にキーで結合する。【選択図】図1
