Kunihiro Umetsu is a prominent inventor based in Anjo, Japan. He has made significant contributions to the field of fuel feed technology, holding a total of 6 patents. His innovative designs focus on enhancing the efficiency and safety of fuel systems.

Latest Patents

One of his latest patents is a fuel feed apparatus having a vibration damping structure. This apparatus accommodates a sub tank that includes a pump module, which generates vibration. The pump module is supported by a supporting member and a suction filter, with the suction filter covered by a nonwoven fabric. This fabric serves as an additional filter to remove debris from the fuel drawn by the pump module. The resilience of both the supporting member and the nonwoven fabric ensures that the vibration from the pump module is not easily transmitted to the sub tank. This design allows for easier manufacturing of the supporting member, as it does not need to be rigidly formed.

Another notable patent is the fuel filter apparatus with an anti-electrostatic function. This apparatus consists of a filter housing made from non-conductive material and a filter element made of conductive material contained within the housing. A conductive plug with a sealing element is inserted into the housing, creating a hermetically sealed environment. The conductive plug is connected to the filter element, allowing static electricity generated in the filter apparatus to be released through a conductive path to an earth wire. This design effectively prevents electrostatic discharge, ensuring safety in fuel systems.
