Latest Patents

One of Sato's latest patents is a hydraulic control apparatus for an automatic transmission. This innovative device features a manual shift valve that outputs both forward range pressure and reverse range pressure. It also includes a linear solenoid valve that provides engagement pressure to the hydraulic servo during reverse travel when energized. The design incorporates a fourth clutch relay valve that ensures the hydraulic servo receives the correct engagement pressure, even during a failure when the solenoid valve is de-energized. This advancement allows for the establishment of reverse speed under failure conditions.

Another significant patent by Sato is also a hydraulic control apparatus for an automatic transmission. This invention includes a solenoid valve that outputs a signal pressure during a failure, while not doing so during normal operation. The first clutch apply relay valve switches between normal and fail positions based on this signal pressure. During a failure, the fail-safe control is activated, allowing the hydraulic servo to maintain engagement pressure, ensuring the system's reliability.
