Latest Patents

Kawakami's latest patents include innovative designs for hydraulically actuated transmissions. One of his patents describes a hydraulically actuated transmission that features a reducing valve in the lubricant oil supplying circuit. This valve is designed to reduce the pressure of the lubricant oil and output it at a lower pressure. Additionally, it includes a switching device that allows for selective switching between two paths for supplying lubricant oil to the to-be-lubricated portion. The output pressure is higher when the second path is selected compared to the first path.

Another patent focuses on a hydraulically operated transmission that incorporates a pressure regulator. This regulator manages the pressure of hydraulic oil supplied to a coupling hydraulic chamber of a frictional coupling element, which is crucial for starting a vehicle. The lubrication control valve in this design ensures that lubricant oil is supplied at a greater flow rate when the regulated pressure is lower than a predetermined threshold, enhancing the efficiency of the coupling process.
