Abstract

PURPOSE:To improve efficiency of power conversion, by converting a fluidic pressure into a linear or rotational force by means of a bellows. CONSTITUTION:Bellows 2 and 2' partitioned by a partition board 3 are incorporated in a cylindrical outer wall 1. A rod 4 passing through the outer wall 1 is fixed to the partition board 3. Thus, a fluidic pressure is converted into a linear or rotational force by means of the bellows 2 and 2'. Since slide resistance according to this arrangement is more reduced than that in the prior art device including a piston.

Description

【発明の詳細な説明】 流体圧を機械的エネルギーに変換させるのに直線方向の

のはアクチュエーター等である。[Detailed Description of the Invention] Fluid pressure is converted into mechanical energy by converting it into force in a linear direction or into force in a rotational direction.The linear force is a cylinder, and the force in the rotational direction is Things are actuators, etc.

摩擦や構造上からシールしにくく洩れの問題がある。Conventional cylinders have various problems due to piston seal sliding resistance, piston's own weight, inertia, etc. Actuators are also similar, and are difficult to seal due to sealing sliding resistance, other friction, and structure, making them difficult to seal and leaking. There is a problem.

ローズを有する構造にした事に依って、この点を解決し
た。The present invention solves this problem by providing a structure in which both the cylinder and actuator have bellows inside their outer walls.

' is built in, and the rod 4 passes through the outer wall 1 and is fixed to the dividing plate 3.

動し、ロッド４もそれに伴って移動する。Now, if the fluid enters through the inlet/outlet 5 of the bellows 2' and the inlet/outlet 6 of the bellows 2 is opened, the volume of the bellows 2' increases, and conversely, the volume of the bellows 2 decreases, so the dividing plate 8 moves and the rod 4 will also move accordingly.

互に流体を進入させると、ロッド４は往復動する。On the other hand, if the rod 4 is entered through the entrance/exit port 6 of the bellows 2, the rod 4 will also move in the opposite direction. Therefore, when fluid enters alternately through the inlets and outlets 5.6, the rod 4 reciprocates.

従来の様なピストンがないので種々の抵抗も減り、動力
変換効率が大巾に向上する。Since there is no piston like in the past, various resistances are reduced and power conversion efficiency is greatly improved.

転軸５は回転する。(2) Regarding the actuator, a bellows which expands and contracts in a fan-like manner is contained inside the cylindrical wall 1, separated by a dividing plate 3.4, and divided into bellows 2.2'. When fluid enters through the Kanayama inlet 6 and releases the entrance/exit lower, and enters the correspondence through the entrance/exit lower and releases the entrance/exit 6, the bellows 2.2' alternately expands and contracts.
Accordingly, the dividing plate 4 is fixed to the rotating shaft 5, and the dividing plate 4 is fixed to the rotating shaft 5.
is fixed to the cylindrical wall IK, so the dividing plate 4 moves and the rotating shaft 5 rotates.

以上の構造のため、摺動抵抗が殆んど無く洩れ等の問題
がない。Due to the above structure, there is almost no sliding resistance and there are no problems such as leakage.
