Title: Electroviscous fluid filled shock absorber
Inventor: YOSHIMURA NAOYUKI
IPC: F16F9/36
Filed: 1993-12-27
Abstract: PURPOSE:To enhance the sealing capacity and durability of a seal member by providing mechanism for separating the micro grain of an electrovisous fluid from base oil, and a return passage for returning the separated micro grain to a reservoir, between the seal member and a bearing. CONSTITUTION:Micro grain contained in an electroviscous fluid is eliminated by a dust lip 16B, and the remaining base oil is eliminated by an oil lip 15B, but large pressure is applied to the dust lip 16B and the oil lip 15B by the accumulation of the eliminated components, so that sufficient sealing function cannot be obtained. In order to prevent the load of this pressure, a recessed part 18 and an oil reservoir chamber 7, and an oil retaining chamber 22a and the oil reservoir chamber 7 are respectively communicated with each other by a return passage 19 and a passage 22b. There is thereby no fear of damaging a piston rod 13 by the micro grain bitten between a seal member and the piston rod 13, so that the sealing capacity and durability of the seal member can be enhanced.
