Latest Patents

Hiroyuki Harada's latest patents include a valve device that features a unique seal ring design. The seal ring consists of a one-end joint forming portion and an other-end joint forming portion. The one-end joint forming portion includes a one-end first contact portion and a one-end second contact portion, which extends in a circumferential direction beyond the one-end first contact portion. The other-end joint forming portion similarly includes an other-end first contact portion and an other-end second contact portion. This innovative design ensures that the inner diameter of the seal ring is less than the outer diameter of the valve element when the one-end first contact portion separates from the other-end second contact portion.

Another patent by Harada describes a valve device that comprises a housing, a valve member, and a valve seat member. The housing features a valve chamber and a housing-space inner wall that forms a housing space communicating with the valve chamber. The housing-side seal portion effectively blocks fluid flow between the valve seat member and the housing-space inner wall. This design incorporates a rubber material for the housing-side seal portion, ensuring an airtight state when fixed to the housing-space inner wall.
