Abstract: A suspension apparatus for use in a vehicle including a body, a body-side member, a wheel, and a wheel-side member, the apparatus including a hydraulic suspension device which is adapted to be provided between the body-side member and the wheel-side member; a first accumulator which is connected to the hydraulic suspension device via a liquid passage and which allows a hydraulic liquid to flow from the liquid passage into the first accumulator when a pressure of the hydraulic liquid in the liquid passage exceeds a first pre-set liquid pressure, the liquid passage including a first portion which is located between an intermediate point thereof and the hydraulic suspension device, and a second portion which is located between the intermediate point thereof and the first accumulator; and a second accumulator which is connected, via a connection passage shorter than the second portion of the liquid passage, to the intermediate point of the liquid passage and which allows the hydraulic liquid to flow from the liqu

Abstract: A vehicle suspension system for a vehicle, including: (a) a plurality of suspension cylinders each disposed between a chassis-side member and a corresponding one of a plurality of wheel-side members; (b) a controller cylinder including a housing and at least one piston slidably mounted in the housing, such that the housing and the at least one piston cooperate to define a plurality of chambers each having a volume that is variable upon slide movement of the at least one piston relative to the housing; (c) individual conduits each communicating a corresponding one of the plurality of chambers of the controller cylinder and a chamber of a corresponding one of the plurality of suspension cylinders; and (d) a suspension-cylinder operation facilitator operable to facilitate an operation of each of the plurality of suspension cylinders for permitting displacement of each of the plurality of wheel-side members relative to the chassis-side member after the at least one piston of the controller cylinder has reached it
