Abstract
Official abstract text for this publication.
An apparatus includes a heat exchanger, a power transmission mechanism, a lubricating oil passage that is located downstream of the heat exchanger and guides lubricating oil to the power transmission mechanism, and a drain oil passage that is located downstream of the heat exchanger and drains the lubricating oil.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus comprising: a heat exchanger; a power transmission mechanism configured to transmit power between a drive source and drive wheels; a lubricating oil passage that is located downstream of the heat exchanger and guides lubricating oil to the power transmission mechanism; a drain oil passage that drains the lubricating oil between the heat exchanger and the power transmission mechanism; and a wall that has a first face and a second face as a back face of the first face, wherein the power transmission mechanism is provided on the first face side of the wall, a member configured with no exposed rotary elements is provided on the second face side of the wall, and the drain oil passage drains the lubricating oil to the second face side of the wall. 2. The apparatus according to claim 1 , wherein the drain oil passage includes a main portion and a throttle portion having a smaller flow path area than that of the main portion. 3. The apparatus according to claim 2 , wherein a length of the throttle portion is shorter than the length of the main portion. 4. The apparatus according to claim 2 , wherein the lubricating oil passage and the drain oil passage are formed in a plate. 5. The apparatus according to claim 4 , wherein one end of the throttle portion opens to a surface of the plate. 6. The apparatus according to claim 2 , wherein the main portion and the throttle portion intersect with each other. 7. A plate comprising: a lubricating oil passage that connects to a downstream side of a heat exchanger; and a drain oil passage that connects to a downstream side of the heat exchanger, wherein the drain oil passage includes a main portion and a throttle portion having a smaller flow path area than that of the main portion, and wherein one end of the throttle portion opens to a surface of the plate. 8. The plate according to claim 7 , wherein a length of the throttle portion is shorter than a length of the main portion. 9. The plate according to claim 7 , wherein the main portion and the throttle portion intersect with each other.
