Patent number: 10316496Abstract: A hydraulic system for a work machine includes a hydraulic pump to supply a pilot fluid, and a hydraulic switch valve to be switched to a plurality of switching positions based on a pilot pressure. The pilot pressure is a pressure of the pilot fluid supplied from the hydraulic pump. The hydraulic system includes a direction switch valve to apply a first pilot pressure to the hydraulic switch valve to switch the hydraulic switch valve into one of the plurality of switching positions. The hydraulic system includes a pressure applying device to apply a second pilot pressure to the hydraulic switch valve. The second pilot pressure is lower than the first pilot pressure.Type: GrantFiled: December 26, 2016Date of Patent: June 11, 2019Assignee: KUBOTA CORPORATIONInventors: Yuji Fukuda, Kazuyoshi Arii, Keisuke Miura, Ryosuke Kinugawa, Ikuhiro Uotani, Satoshi Tajima, Ryohei Sumiyoshi, Kunihiro Suzuki

Patent number: 10049832Abstract: A displacement switch includes a main operation portion having a hollow shape. The main operation portion includes a top surface via which the displacement switch is operated, and a side surface connected to the top surface to define the hollow shape. The displacement switch also includes a support member connected to the main operation portion and swingable around a swing axis together with the main operation portion, and a base including a peripheral wall surrounding an insertion inlet into which the support member is inserted. The main operation portion covers the insertion inlet such that the side surface surrounds an outer peripheral surface of the peripheral wall.Type: GrantFiled: June 16, 2016Date of Patent: August 14, 2018Assignee: KUBOTA CORPORATIONInventors: Hiroaki Nakagawa, Masahiro Kuroda, Keisuke Miura, Ikuhiro Uotani, Satoshi Tajima, Hiroyuki Anami, Hayato Kawano

Publication number: 20170029007Abstract: A displacement switch includes a first wall, a second wall, a third wall, a fourth wall, a support member, and a base. The first wall is disposed on a first side in a width direction and includes a first standing portion. The second wall is disposed on a second side opposite to the first side in the width direction and includes a second standing portion. The third wall connects the first standing portion and the second standing portion. The fourth wall includes an operation surface and connects the first wall, the second wall and the third wall. The support member is swingably disposed on at least one of the first wall, the second wall, the third wall and the fourth wall. The base overlaps the third wall viewed in a first direction perpendicular to the third wall. The base includes an insertion inlet into which the support member is inserted.Type: ApplicationFiled: June 16, 2016Publication date: February 2, 2017Applicant: KUBOTA CORPORATIONInventors: Hiroaki NAKAGAWA, Masahiro KURODA, Keisuke MIURA, Ikuhiro UOTANI, Satoshi TAJIMA, Hiroyuki ANAMI, Hayato KAWANO
