Latest Patents

Mochiyama's latest patents focus on the design and functionality of variable displacement pumps. In one of his patents, a pressurizing cylinder is positioned on the opposite side of the first fluid pressure chamber, with a cam ring held in between. A piston inserted into the pressurizing cylinder collides with the cam ring, allowing for precise control of fluid dynamics. The design includes an oil chamber interposed in the pump discharge side passage, where pressures from both upstream and downstream sides of the main throttle are introduced to optimize performance.

Another patent further refines this concept by introducing a pressure in the upstream side of both throttle passages, which includes a variable throttle passage and a fixed throttle passage. This innovation allows for improved control over the fluid pressure in the system, enhancing the overall efficiency of the pump.
