Claims (3)
- オイルポンプから変速機の摺動部品に供給される変速機油の温度を調整する油温調整装置であって、
前記オイルポンプ側に設けられる上流側油路と前記摺動部品側に設けられる下流側油路との間に設置される放熱器と、
前記上流側油路に設けられ、下流側から上流側に向かう変速機油の流れを阻止する逆止弁と、
前記下流側油路と前記逆止弁の上流側の前記上流側油路とに接続され、前記逆止弁および前記放熱器を迂回して変速機油を案内するバイパス油路と、
前記バイパス油路に設けられ、前記バイパス油路を連通する連通状態と遮断する遮断状態とに切り換えられる切換弁と、を有し、
変速機油の低温時には前記切換弁を連通状態に切り換える一方、変速機油の高温時には前記切換弁を遮断状態に切り換えることを特徴とする油温調整装置。 - 請求項1記載の油温調整装置において、
前記切換弁はサーモスタットであることを特徴とする油温調整装置。 - 請求項1または2記載の油温調整装置において、
前記逆止弁は、前記逆止弁の上流側に作用する変速機油が所定圧力を超えたときに、上流側から下流側に向かう変速機油の流れを許容することを特徴とする油温調整装置。
