また油室４に導く油圧は油ポンプの咄出油圧を調整した
ライン油圧に限定されずガバナ油圧その他であっても良
いが油圧の高いライン油の導入が望ましい。Further, the oil pressure introduced into the oil chamber 4 is not limited to the line oil pressure obtained by adjusting the output oil pressure of the oil pump, and may be a governor oil pressure or other oil pressure, but it is preferable to introduce line oil with a high oil pressure.
