Description
Claims (5)
- シリンダと、
前記シリンダ内を軸方向に移動自在に挿入されるロッドと、
前記ロッドの先端に連結されるとともに、減衰力調整バルブを保持する筒状のハウジングとを備え、
前記ハウジングに前記シリンダ内を伸側室と圧側室に区画するピストンが装着されていることを特徴とする緩衝器。 - 前記減衰力調整バルブと前記ハウジングとの間に、前記ハウジングの前記減衰力調整バルブに対する傾きを許容する変位吸収部材を備えることを特徴とする請求項1に記載の緩衝器。
- 前記減衰力調整バルブが、
前記ハウジング内を区画するとともに前記伸側室と前記圧側室を連通する通路を有する隔壁部材と、前記隔壁部材に積層されて前記通路を開閉する弁体と、前記弁体を内部圧力で閉方向に附勢する背圧室を形成する背圧室形成部材とを備える減衰部と、
前記内部圧力を制御する電磁弁とを備えることを特徴とする請求項1または2に記載の緩衝器。 - 前記電磁弁は、弁部と前記弁部を嵌合するソレノイドを備え、
前記ソレノイドと前記弁部との間に前記変位吸収部材を設けたことを特徴とする請求項2を引用する請求項3に記載の緩衝器。 - 前記減衰部は前記ハウジングの先端側に連結されており、
前記電磁弁は前記ハウジングの基端側に収容されており、
