| 发明名称 | Powertrain pressure and flow control system for automatic transmissions | ||
| 摘要 | A pressure and flow control system includes a hydraulically-controlled component, a pilot valve, and a regulating valve. The pilot valve is configured to produce a pilot signal and includes a first valve, which is a MEMS microvalve. The regulating valve is in fluid communication with the pilot valve, and is configured to receive the pilot signal. The regulating valve is further configured to output a control signal, which controls the hydraulically-controlled component. | ||

| 主权项 | 1. A pressure and flow control system for an automatic transmission, the pressure and flow control system comprising: a hydraulically-controlled component disposed within the automatic transmission; a MEMS Micro Electro Mechanical Systems) pilot microvalve configured to output an unamplified pilot signal; and a mechanical regulating valve in fluid communication with the MEMS pilot microvalve, wherein the mechanical regulating valve is configured to receive the unamplified pilot signal and is configured to output an amplified control signal which controls the hydraulically-controlled component. | ||
