Description
Claims (1)
- 【特許請求の範囲】 1. 以下で構成される可変的なバルブタイミングシステムすなわち; バルブの開閉位置の間でバルブを移動させるために適当な受動車。該受動車はそ の輪郭に沿った噛み合わせ面を持つ、 カム、これはカムシャフトの上部に位置し、カムシャフトによって駆動され、 受動車の噛み合わせ面との噛み合わせに適した噛み合わせ面を有し、バルブを操 作するためのカムを作動させる。カムの接触面は少なくともその部分に沿って周 回する、また、 回転の媒介手段は受動車をカムの運動の水準に応じて回転させるものであるが 、その運動は縁取られたカムの接触面と縁取られた受動車の接触面が、受動車が 回転していない場合に比して、互いにより早期に噛み合い、より遅れて噛み合わ せを解くようになっている。 2. 受動車の輪郭に沿った噛み合わせ面の断面がV字型である、請求の範囲1に 記載の可変的なバルブタイミングシステム。 3.2つの揺り子状の挿入物が受動車の噛み合わせ面を形成する、請求の範囲1〜 2のいずれかに記載の可変的なバルブタイミングシステム。 4.受動車の内部および凹部に位置する揺り子状の挿入物で、凹部を持ち、この 凹部によって揺り子状の挿入物の端を滑らせ、揺り子状の挿入物をそれぞれの凹 部に保持する、請求の範囲3に記載の可変的なバルブタイミングシステム。 5.該回転手段が操作用ロッドで構成されるとともに、個々の受動車がU字型の 連結横木の2本の腕の中に保持され、連結横木がシャフトによって操作用ロッド 上の浮動する球体状の組み立て部品に連結されている、請求範囲1〜4のいず れかに記載の可変的なバルブタイミングシステム。 6.操作用ロッドが、個々の球体状の組み立て部品の間でその長さを変化させう る手段を備え、そして、カムと受動車を必要に応じて直線上に整列させる、請求 の範囲5に記載の可変的なバルブタイミングシステム。 7.添付図面を参照しながらその概要を記述した、可変的なバルブタイミングシ ステム。
