Title: Suspension apparatus having two interconnected shock absorbers

Abstract: The pilot suspension apparatus of the present invention is capable of biasing a damping valve in a direction for closing the valve, due to application of a pilot pressure. The suspension apparatus comprises at least one pair of hydraulic shock absorbers which are capable of controlling a damping force and which are connected by a connecting pipe. The at least one pair of hydraulic shock absorbers are provided at front and rear wheels or left and right wheels on the same side of a vehicle or are provided in a diagonally shaped relationship. A control valve is provided so as to control the pilot pressure. The control valve is adapted to be controlled by application of a differential pressure which is generated between respective cylinders of the at least one pair of shock absorbers.
