Latest Patents

One of Pfister's latest patents is a hydraulic supply system designed for a hydraulically actuated automatic transmission. This innovative system is particularly suited for belt-driven conical-pulley transmissions. It features a primary pump that is driven by a primary drive system, providing pressure in a supply line connected to a regulating valve. The supply line is linked through a pilot valve to a control line, where a control valve is located. This control valve is crucial for setting the pressure that determines the adjustment of the transmission ratio. Additionally, Pfister has developed a hydraulic system for actuating a belt-driven conical-pulley transmission with a variably adjustable transmission ratio. This system includes at least one hydraulic energy source and a torque sensor that is supplied with working medium by a pump flow from the hydraulic energy source.
