Claims (10)
- 車両の圧縮空気ブレーキシステムに用いられる電空式の調整弁であって、リレー弁ハウジング(1)が設けられており、該リレー弁ハウジング(1)内に、外部に位置する少なくとも1つのブレーキ管路接続部(11)と、供給圧接続部と、空気抜き接続部(13)との間で圧縮空気流を切り換える弁座装置(8)を操作するための軸方向に調節可能な制御ピストン(5)が配置されており、該制御ピストン(5)が、同軸的な案内装置を介して軸方向に案内されていて、軸方向調節のための電磁式の少なくとも1つのパイロット制御弁(6)を介して負荷可能であり、該パイロット制御弁(6)が、リレー弁ハウジング(1)に結合されたパイロット制御弁ハウジング(2)内に収納されている形式のものにおいて、
制御ピストン(5)の案内装置が、パイロット制御弁ハウジング(2)に不動に固定された別個の案内スリーブ(17)を有しており、該案内スリーブ(17)が、上側の案内区分(19)を備えており、該案内区分(19)が、軸方向の案内のために、制御ピストン(5)に設けられた貫通孔(18)に対応しており、さらに、案内装置が、上側の案内区分(19)に続く、より小さな外径の下側の管区分(20)を有しており、これによって、該下側の管区分(20)に組み込まれた軸方向の空気抜き通路(21)を通流する排出空気が、リレー弁ハウジング(1)とパイロット制御弁ハウジング(2)とによって閉鎖された内部に位置する制御チャンバ(4)から弁座装置(8)の領域を越えて直接空気抜き接続部(13)にガイドされるようになっていることを特徴とする、車両の圧縮空気ブレーキシステムに用いられる電空式の調整弁。 - 空気抜き接続部(13)が、流出する排出空気によって生ぜしめられる騒音を最小限に抑えるために、消音器(14)を備えている、請求項1記載の調整弁。
- 案内スリーブ(17)が、少なくとも案内区分(19)の領域で、僅かな滑り摩擦係数を備えたプラスチックから成っている、請求項1記載の調整弁。
- 案内スリーブ(17)をパイロット制御弁ハウジング(2)に固定するために、該パイロット制御弁ハウジング(2)に一体成形された中空の案内ピン(16)が設けられており、該案内ピン(16)が、摩擦接続的なプレス嵌めを介して案内スリーブ(17)との結合部を形成している、請求項1記載の調整弁。
- 案内スリーブ(17)が、案内区分(19)の領域に、空気抜き通路(21)に対してほぼ同軸的に延びる、より大きな直径の切欠き(22)を有しており、該切欠き(22)を介して、案内ピン(16)へのプレス嵌めによる固定が行われるようになっている、請求項4記載の調整弁。
- 切欠き(22)の内部に、軸方向で間隔を置いて配置された環状の2つの嵌合区分(23a,23b)が設けられており、両嵌合区分(23a,23b)が、プレス嵌め時に案内ピン(16)に当て付けられるようになっている、請求項5記載の調整弁。
- リレー弁ハウジング(1)に対して不動に案内スリーブ(17)の形状接続的な端部側の位置決めを可能にするために、管区分(20)の末端領域に段部(24)が形成されている、請求項1記載の調整弁。
- 空気抜き通路(21)から流出する排出空気の妨害されない流出を保証するために、管区分(20)の末端が開裂されて形成されている、請求項1記載の調整弁。
- 空気抜き通路(21)の流れ横断面最大化のために、管区分(20)の壁が、リブ装置を介して補強されており、これによって、管区分(20)の領域における所要の肉厚と総直径とが最小値に寸法設定されている、請求項1記載の調整弁。
- リブ装置が、管区分(20)の外壁に沿って軸方向に延びる、管区分(20)に対してほぼ軸線平行に方向付けられた、横断面で見て互いに等距離で配置された少なくとも4つのリブ一体成形部(26a,26b,26c,26d)から成っている、請求項9記載の調整弁。
