Document Type and Number:

Japanese Patent JPS5830544

Kind Code:

A

Abstract:

PURPOSE:To improve feeling upon riding on a vehicle or the steering stability of the vehicle by a method wherein a running condition such as the sudden starting or the high-speed running of the vehicle is detected from the opening degree signal of a throttle and a shift position signal to increase the damping force of a shock absorber temporarily. CONSTITUTION:When an exciting current is supplied to solenoid coil 50 and a plunger 52 is attracted and moved to the left against a spring 54, a variable orifice 40 is closed by a valve 52a and, under this condition, the communicating sectional area of a shock absorber becomes a small area determined by orifices 30, 32, or the same 33, 34, thereby enabling to vary and adjust the damping force temporarily. Accordingly, the comforatable feeling upon riding on a vehicle and the good steering stability of the vehicle may be obtained by a method wherein the running condition of the vehicle such as the sudden starting or the high-speed running, for example, is detected by the opening degree signal of the throttle for an engine and the shift position signal of a speed change mechanism by exciting the solneoid coil 50.
