Abstract
Description
Claims (1)
- 【特許請求の範囲】 1.内燃機関、特に、大型の舶用ディーゼルエンであって、ピストンとピスト ンロッドとの間の動力伝達部材として、ピストンヘッドと一体の環状リブと、ピ ストンヘッドから下方を向き且つ外側のピストンリングが設けられたピストンの 側壁との間の環状領域内にてリブ支持要素が設けられ、該リブ支持要素が円錐形 壁にて下方に終わっており、該円錐形壁には、冷却オイルが流れるため、ピスト ンの軸線と略平行に伸長する穴が貫通し、該円錐形壁は、ピストンの軸方向断面 にて見たとき、丸味を付けた壁部分により側壁と接続され、該丸味を付けた壁部 分を貫通して軸方向部分が略円の形状を有するピストンにおいて、 丸味を付けた壁部分が、肉厚の薄い側壁の一部分内に伸長する、それ自体公知 の伸長部を有し、該伸長部が、丸味を付けた部分に沿った軸方向部分が円の一部 の形状を有し、冷却穴の各々に対してこの軸線から最も遠方に配置された母線よ りもピストンの軸線に対して近くない位置に前記円の中心を配置することを可能 にすることを特徴とするピストン。 2.請求項1に記載のピストンにおいて、 側壁の薄い肉厚を有する領域が、ピストンリングよりもピストンヘッドにより 近い位置に配置されることを特徴とするピストン。 3.請求項2に記載のピストンにおいて、 肉厚の薄い側壁の領域が、最上方ピストンリングの上方におけるピストンリン グの高さの約1/2から丸味を付けた壁部分まで伸長することを特徴とするピス トン。
