Abstract
Description
図1に示すように、本発明の第一の実施の形態に係るソレノイドを含む電磁弁Vを備えた緩衝器Dは、シリンダ1と、このシリンダ1内に摺動自在に挿入されるピストン10と、一端がピストン10に連結されて他端がシリンダ1外へ突出するピストンロッド11とを備える。そして、車両における車体と車軸の一方にシリンダ1が連結され、他方にピストンロッド11が連結される。このように、緩衝器Dは車体と車軸との間に介装される。
つづいて、図7に示す本発明の第二の実施の形態に係るソレノイドS2について説明する。本実施の形態に係るソレノイドS2は、第一の実施の形態のソレノイドS1と同様に、電磁弁に利用されており、図2に示す第一の実施の形態のソレノイドS1を、そのまま本実施の形態のソレノイドS2に置き換えることができる。また、本実施の形態に係るソレノイドS2の基本的な構造は、第一の実施の形態に係るソレノイドS1と同様であり、共通の構成については同一符号を付して詳細な説明を省略する。
