Publication number: 20250043782Abstract: The objective of the present invention is to provide a liquid feed system for a compressor, capable of easily forming fine droplets of a liquid to be injected into the compressor. A liquid feed system 100 of a compressor 1 for compressing a gas injects a liquid 50 into the inside of the compressor 1. The liquid feed system 100 adjusts the temperature of the liquid 50 to be injected into the compressor 1 to a temperature at least equal to a saturation temperature Tf corresponding to a pressure inside the compressor 1, and adjusts the temperature to a temperature lower than a saturation temperature Ti corresponding to a pressure of the liquid 50 at the time of injection into the compressor 1, and then injects the liquid 50 into the compressor 1.Type: ApplicationFiled: October 11, 2022Publication date: February 6, 2025Applicant: Hitachi, Ltd.Inventors: Tomoyuki HOSAKA, Eiji ISHII, Kazuki YOSHIMURA

Patent number: 10690183Abstract: In this motion guide device (10), a track member (20) has a recess or protrusion (51) that is formed in a longitudinal direction, and a moving member (30) has a holding protrusion or holding recess (53) that corresponds to the recess or protrusion (51) formed in the track member (20). When force is applied in a direction that would cause relative separation of the moving member (30) and the track member (20), the holding protrusion or holding recess (53) holds onto the recess or protrusion (51) such that the moving member (30) and the track member (20) are unable to be separated. With this configuration, a motion guide device that is both compact and capable of withstanding a strong external load can be obtained.Type: GrantFiled: August 18, 2017Date of Patent: June 23, 2020Assignee: THK CO., LTDInventors: Hiroaki Mochizuki, Eiji Hosaka, Hiroomi Kuribayashi, Toshiro Minami, Akito Kaneko
