Title: Damping force changeable type hydraulic damper
Inventor: YAMAOKA FUMIYUKI
IPC: F16F9/44
Filed: 1988-09-19
Abstract: PURPOSE:To obtain a linear damping force characteristic by disposing a variable orifice in the intermediate part of one of a first communicating passage communicating an inner groove with an upper liquid chamber and a second communicating passage communicating an outer groove with the upper liquid chamber. CONSTITUTION:When the hydraulic pressure in an upper liquid chamber A increases during extending stroke of a piston 2, the hydraulic pressures of inner and outer grooves 7c, 7d are increased through both first and second communicating passages 7e, 3a to 3d so as to pen an extension side disc valve 8, and accordingly hydraulic fluid flows into a lower liquid chamber B. That is, hydraulic fluid passing through the first communicating passage 7e flows through the inner groove 7c and a gap between an inner seat 7f and an extension side disc valve 8 and then through a gap between an outer seat surface 7f and the disc valve 8, and finally flows into the lower liquid chamber B. In this case, constriction occurs at two positions in series, that is, the positions of the inner and outer set surfaces 7f, 7h between the extension side disc valve 8 and the piston 2 so as to produce a damping force in a low speed range, and a damping force is produced on the communicating passage side including a variable orifice 15 in an intermediate or high speed range in which these construction parts are largely opened. Thus, it is possible to aim at making both manipulating stability and drive comfortability compatible over the entire range.
