Abstract
Description
Claims (1)
- 内燃機関のためのピストンであって、軸範囲を形成する下部と、該下部に膨張ねじを介して結合された、ピストンクラウンと環状範囲とを形成するピストン上部とが設けられており、ピストン下部内に設けられた膨張ねじが、ピストン下部に設けられたそれぞれの孔に係合する押圧部材に位置しており、押圧部材とピストン下部との間のそれぞれの接触が、互いに傾斜されて延びる面を介して得られるようになっている形式のものにおいて、
押圧部材(2)のためのピストン下部(1)の載着面が、一般的な式x2/a2+y2/a2+z2/c2=1の長く延びた回転楕円体の面に従っており、x,y及びzが、空間軸線を規定しており、かつa及びcが、a<cにより半軸線を規定しており、
長く延びた回転楕円体の空間軸線zが、押圧部材(2)を収容するためのそれぞれの孔の軸線と一致しており、かつ押圧部材(2)の載着面が、一般的な式x2+y2+z2=rk2の球の面に従っており、rk<aであることを特徴とする、内燃機関のためのピストン。
