Description
実施の形態1.
図1は、実施の形態1に係るWGアクチュエータ1の構成例を示す断面図である。ターボチャージャは、エンジンからの排気ガスによってタービンを回転させ、このタービンと同軸で接続されたコンプレッサを駆動して吸気を圧縮しエンジンに供給する構成である。排気通路100のタービン上流側には、排気ガスを排気通路100からバイパス通路101へ逃がすWGバルブ2が設置されており、WGアクチュエータ1がWGバルブ2を開閉して排気通路100からバイパス通路101への排気ガス流入量を調整することにより、タービンの回転数を制御する。なお、図1では、WGバルブ2の全閉状態を実線で示し、全開状態を二点鎖線で示す。
なお、図1では直流モータ4としてブラシ付きDCモータを使用しているが、ブラシレスDCモータを使用してもよい。
ここでは、図1に示したWGアクチュエータ1において、WGバルブ2の全閉位置までシャフト13をハウジング15内に引き込んだときに、ストッパ15cと当て部13cとが当接してシャフト13の移動を規制する構成とする。この構成において、制御装置20は、位置センサ16により検出されるシャフト13の実ストローク位置に基づいて、WGバルブ2の全閉位置までシャフト13を引き込んだと判定したとき、判定時から予め定められた時間が経過するまでのあいだ直流モータ4への通電電流を維持して、当該シャフト13の当て部13cがストッパ15cに当接した状態でロータ6を回転させてネジ機構12を増し締めする。これにより、雌ネジ部12aと雄ネジ部12bの間の摩擦力が大きくなり、負荷Wがかかったとしてもシャフト13は回転しにくくなる。よって、上述の予め定められた時間が経過した後、シャフト13をWGバルブ2の全閉位置に保持する際、保持電流を小さくできる。なお、上述の予め定められた時間は、制御装置20内のメモリに予め記憶されているものとする。
また、本発明に係るWGアクチュエータ1と、駆動対象物であるWGバルブ2とを備えたWGバルブ駆動装置として構成してもよい。
