<p>PURPOSE:To keep an oil level almost constant at all times even when a car speed varies, by controlling the feed or discharge of oil to or from a sub- reservoir tank according to the car speed. CONSTITUTION:An oil passage 26 is connected to a sub-reservoir tank 12, and a drain oil passage 28 is constituted so as to discharge oil to a main reservoir tank 10. In addition, dowernor pressure PG being varied correspondent to a car speed is fed to a lower end face of a spool 30 from an oil passage 32. This spool 30 is being pressed downward by a spring 34. The main reservoir tank 10 is made possible to deliver the oil to a differential mechanism 38 to be set up in the same casing as well via a connecting space inside the casing. With this constitution, if the car speed is varied, an oil level can be kept constant at all times.</p> |
