Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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 re…
