SHOCK ABSORBER WITH VEHICLE HEIGHT ADJUSTMENT FUNCTION

WIPO Patent Application WO/2023/007550

A1

A shock absorber (D1) with a vehicle height adjustment function in the present invention includes: a shock absorber body (1) having a cylinder (2) filled with liquid, a piston (3) dividing the inside of the cylinder (2) into an expansion-side chamber (R1) and a compression-side chamber (R2), and a piston rod (4) coupled to the piston (3); a suspension spring (S) that urges the shock absorber body (1) in the expansion direction; a reservoir (R) storing a liquid; a damper circuit (C1) that is connected to the expansion-side chamber (R1), the compression-side chamber (R2) and the reservoir (R) to generate a damping force in the shock absorber body (1) when the shock absorber body (1) expands and contracts; a pump (P) capable of sucking and discharging the liquid from the reservoir (R); and a switching valve (V1) that is installed between the shock absorber body (1) and the damper circuit (C1) and the pump (P) and is capable of switching between a damper mode in which the shock absorber body (1) is connected to the damper circuit (C1) to generate the damping force to the shock absorber body (1), and a vehicle height adjustment mode in which the shock absorber body (1) is connected to the pump (P).
