In 1795, Joseph Braman (1749-1814) of England developed the world's first hydraulic press, using water as the working medium and applying it industrially in the form of a hydraulic press. In 1905, the working medium was changed from water to oil, further improving the technology.
After World War I (1914-1918), hydraulic transmission was widely used, especially after 1920, with rapid development. Hydraulic components only began to enter formal industrial production in the two decades between the late 19th and early 20th centuries. In 1925, F. Vikers invented the pressure-balanced vane pump, laying the foundation for the gradual establishment of the modern hydraulic component industry and hydraulic transmission. Constantin Nissko's theoretical and practical research on energy fluctuation transmission in the early 20th century, and his contributions to hydraulic transmission (hydraulic couplings, hydraulic torque converters, etc.) in 1910, further advanced these two fields.
During World War II (1941-1945), 30% of machine tools in the United States used hydraulic transmissions. It should be noted that Japan's development of hydraulic transmissions lagged behind Europe and the United States by nearly 20 years. Around 1955, Japan rapidly developed hydraulic transmissions, and in 1956, the "Hydraulic Industry Association" was established. In the past 20-30 years, Japan's development of hydraulic transmissions has been so rapid that it has been among the world's leading countries.
