Patent number: 8567575Abstract: A shock absorber, in which external gas is sucked by movement of a piston rod to obtain compressed gas, which is used for inhibiting the “lag” phenomenon. A piston valve is connected to one end of a piston rod received in an inner shell and moved between rebound and compression strokes, an inner space of the inner shell being divided into a rebound chamber and a compression chamber by the piston valve. A reservoir chamber is provided in an outer shell outside of the inner shell to supply oil to the compression chamber in the rebound stroke and to recover oil in the compression stroke. The shock absorber has a high pressure tank with a high pressure chamber installed outside of the outer shell, and a self pumping unit for sucking gas and pumping it into the high pressure chamber using energy generated by movement of the piston rod.Type: GrantFiled: November 16, 2011Date of Patent: October 29, 2013Assignee: Mando CorporationInventors: Woo Jin Jung, Myung Hwa Hyun

Patent number: 8556281Abstract: A bracket is provided to mount a shock absorber to a vehicle body. The bracket is configured to couple a distal end of a piston rod of the shock absorber to a vehicle body. The bracket is molded of a plastic material and includes a body having a recess formed thereon, the recess allowing a bush assembly to be inserted therein, and a flange extending from the body. The bracket is molded integrally with a metal insert.Type: GrantFiled: November 10, 2009Date of Patent: October 15, 2013Assignee: Mando CorporationInventors: Yoon Hyun Lee, Myung Hwa Hyun

Publication number: 20070125612Abstract: A dust cover partially encloses a piston rod and a cylinder of a shock absorber to prevent foreign materials from being introduced into the cylinder via the piston rod. The dust cover includes at least two covers configured to be separated vertically and have ends overlapping with and sliding on each other. A gap between the two covers is defined to be directed upward.Type: ApplicationFiled: December 1, 2006Publication date: June 7, 2007Applicant: MANDO CORPORATIONInventors: Myung Hwa Hyun, Eun Pyo Hong
