Nachi America, Inc.’s (Greenwood, IN) automotive hydraulics division has developed a 2-way automatic transmission valve that supports the increased OE demands for large volumes of transmission fluid. New architecture features like Idle Stop technology require a higher flow of fluid to clutches. According to the company, its design is one answer to this challenge: the design can fill the accumulator in a short time to prepare the system for the next cycle. It’s capable of 40 L/min (10.6 gal/min) while working with a low differential pressure application of 800 kPa (116 psi) at 80°C (176°F), while also keeping the leakage to a minimum of 1.5 cc/min.
