摘要：
A continuously variable transmission (CVT) for a vehicle includes a hydraulically-controlled component and a pilot valve. The pilot valve includes at least one micro-electrical-mechanical-systems (MEMS) based device. The pilot valve is operably connected to and is configured for actuating the hydraulically-controlled component. The pilot valve additionally includes a regulating valve operably connected to the pilot valve and to the hydraulically-controlled component. The regulating valve is configured to direct fluid to the hydraulically-controlled component when actuated by the pilot valve.
