Abstract
A transmission includes a high-pressure circuit at least partially filled with transmission fluid at a first pressure, and a low-pressure circuit at least partially filled with transmission fluid at a second pressure, which is lower than the first pressure. A diffuser is in fluid communication with the high-pressure circuit and the low-pressure circuit. The diffuser has an inlet having a first cross-sectional area and receiving transmission fluid from the high-pressure circuit. The diffuser expels transmission fluid to the low-pressure circuit through an outlet having a second cross-sectional area, which is larger than the first cross-sectional area.
