Latest Patents
Yamamura's latest patents include two key innovations: a seal mechanism and a high pressure fuel pump. The seal mechanism presents an advanced design that enhances pressure tightness, effectively eliminating the need for return piping to a fuel tank, which is typically required to alleviate pressure on the seal in high-pressure fuel pumps. Moreover, it features a stress reduction mechanism that minimizes stress at the junction between its retaining and flexible members.
His high-pressure fuel pump innovation introduces an axial plunger design that does away with traditional bellows. Instead, it leverages a system that restricts fuel to a cylinder bore while employing oil lubrication in other sections of the pump. The pump includes a reciprocating plunger regulated by the motion of a swash plate, along with a cylinder block that creates a pump chamber. A sealing member plays a crucial role in preventing oil leaks from the chamber.
