| 【課題】スクロール部材を用いた流体機械のシール性を向上させるとともに、耐摩耗性を向上させる。 【解決手段】樹脂層L1の表面には複数の溝Cが形成されている。溝Cの断面は、深い位置ほど幅が狭くなり底に近づくほど幅の変化が急になるU字ないし半円に似た形状である。溝Cは、塗布などによって基材L0上に最初に形成された樹脂層の元の表面に沿って切削工具の刃先を移動させて形成される。この溝Cの幅wは、隣り合う溝C同士の間隔pと同じか間隔pよりも小さい。樹脂層の元の表面は削られて無くなっているか、隣り合う溝C同士の間に形成される山部Bの先端のみとなる。この先端が尖っていると山部Bは弾性変形を起こしやすい形状となる。また、溝Cの深さdは、隣り合う溝C同士の間隔pよりも小さい。そのため、隣り合う溝C同士の間に形成される山部Bは、高さよりも裾部分の幅の方が長く、横方向の力に対して比較的頑丈な形状となる。 【選択図】図3 |

| Disclosed is a method for producing superheated steam in an engine by injecting highly compressed water into a very hot liquid, synthetic medium located in the engine, resulting in explosion-like evaporation. This process is to take place in a specially developed rotary-translational engine in order to be able to use a maximum of the thrust of the steam. The engine is to be provided with at least two cylinders which have a circular cross-sectional shape (10) and inside which the drive shaft (11) is disposed eccentrically. A rotor (12) is arranged on the drive shaft. Said rotor (12) is connected to an element (16) that is inserted through the drive shaft (11) and can be moved back and forth therein while the ends of said element (16) are fixedly anchored to the rotor (12). The two ends of the rotor (10) are equipped with a specially developed triple-roll seal (13) that can lengthen and shorten the rotor (10), which is required when the drive shaft (11) is placed non-axially in a circular cylinder (10). The rotor (10) has an elongate, elliptical shape and divides the cylinder chamber (10) into two expanding and contracting working chambers A and B. | ||||||
