Patent number: 10180132Abstract: A flow generator includes pumps operated by motors to generate an amount of a hydraulic fluid, a proportional hydraulic control valve to control output hydraulic pressure according to the amount of the hydraulic fluid, a pressure sensor to detect the output hydraulic pressure, and a hydraulic servo loop controller to which a required hydraulic pressure and a required amount of fluid are input by a user. Based on a feedback signal representing the output hydraulic pressure, the controller generates a pressure control signal for controlling the proportional hydraulic control valve based on the required hydraulic pressure and a change in the output hydraulic pressure. It also generates an RPM input signal for controlling a motor's RPM.Type: GrantFiled: July 10, 2014Date of Patent: January 15, 2019Assignee: KNR Systems, Inc.Inventors: Sung Moo Ryu, Seong Cheol Jang, Hyoung Kwon Kim, Young Ho Choo, Dae Gyeong Kim

Patent number: 9976577Abstract: In the integrated hydraulic rotary actuator according to the present invention, a valve, a sensor, a controller, and a driving unit for controlling the rotary actuator are integrated, so wires connecting them are not exposed to the outside. Accordingly, it is possible to prevent damage due to interference in operation and maintenance is easy. Further, since it is integrated, including a controller, when the actuator according to the present invention is used, connecting with other parts is easy and interference can be reduced. Therefore, it is easy to design and manufacture a resultant product.Type: GrantFiled: April 30, 2015Date of Patent: May 22, 2018Assignee: KNR SYSTEMS INC.Inventors: Sung Moo Ryu, Ki Tak Ahn, Gyu Young Lee
