Claims (8)
- 圧力脈動を減衰する減衰装置(18)であって、減衰容積を制限するケーシング(20)を有し、該ケーシング(20)が圧力媒体を貫流させるために前記ケーシング(20)内へ開口する供給部(22a)と前記ケーシング(20)の外へ開口する排出部(22b)とを有し、排出部(22b)の領域に配置された絞り(32)と該絞り(32)の上流側に接続されたフィルタ(26)とを有しており、前記フィルタ(26)と該フィルタ(26)が合流する点において形成される前記絞り(32)とが、前記ケーシング(20)の内部に固定される、非切削加工で製作される一体の機能エレメント(24)に纏められており、
前記排出部(22b)が前記供給部(22a)と同じ側でケーシングから導出され、前記機能エレメント(24)が、第1のエレメント部分(24a)と第2のエレメント部分(24b)とを有しており、該第1のエレメント部分(24a)が、前記供給部(22a)の開口横断面の領域に圧密に固定されており、該第2のエレメント部分(24b)の端面が、排出部22bの横断面を覆っていることを特徴とする、圧力脈動を減衰する減衰装置。 - 前記フィルタ(26)と前記絞り(32)の横断面が前記機能エレメント(24)の管状の第1のエレメント部分(24a)の長手方向軸線に対し横に配向されており、前記第2のエレメント部分(24b)が前記ケーシング(20)の内部へ向かって閉じられかつ前記排出部(22b)に向かって開放した切欠き(30)を有し、該切欠き(30)に前記絞り(32)の横断面が開口している、請求項1記載の減衰装置。
- 前記フィルタ(26)の横断面が少なくとも1つの合流点にて合流しており、この合流点が前記絞り(32)を形成している、請求項2記載の減衰装置。
- 前記機能エレメント(24)に、組込まれた状態で認識可能な方向付け補助手段(28)が少なくとも1つ配置されており、該方向付け補助手段(28)が前記フィルタ(26)に対する相対位置に基づき前記機能エレメント(24)の方向付けを可能にしている、請求項1から3までのいずれか1項記載の減衰装置。
- 前記機能エレメント(24)が射出成形技術によりプラスチックから製作されている、請求項1から4までのいずれか1項記載の減衰装置。
- 前記機能エレメント(24)が筒状の第1のエレメント部分(24a)を有し、この第1のエレメント部分(24a)が当該減衰装置(18)の前記供給部(22a)へプレス嵌めされている、請求項1から5までのいずれか1項記載の減衰装置。
- 電子的に調整可能な車両ブレーキ装置のための液圧装置(10)であって、組込み室(14)を有するケーシングブロック(12)と、該ケーシングブロック(12)に配置された、駆動エレメントを作動するためのモータと、駆動エレメントにより負荷されたポンプと、圧力媒体を案内するために前記ケーシングブロック(12)に設けられた通路(16)とを有し、圧力媒体を案内する前記通路(16)内の圧力を調整するための弁が前記通路(16)に設けられており、圧力を調整するために前記弁が電気的な制御装置により制御可能であり、圧力脈動を減衰するために請求項1から6までのいずれか1項記載の減衰装置(18)を有していることを特徴とする、液圧装置。
- 前記減衰装置(18)がそのケーシング(20)で前記ケーシングブロック(12)の外面から突出しており、この外面が電子的な制御装置を固定するために構成されている、請求項7記載の液圧装置。
