Suspension apparatus

摘要

If the control to decrease the vehicle height is executed while a spring-constant switching valve (28FL) is closed, and the spring-constant switching valve (28FL) is opened after the control is completed, operating fluid suddenly flows from an accumulator (26FL). This causes pulsation. If the spring-constant switching valve (28FL) is opened while the communication-valve (112) is open, the operating fluid flowing from the accumulator (26FL) is supplied to a suspension cylinder (10FL) and a high-pressure accumulator (24FL) corresponding a front-left wheel (4FL), and a suspension cylinder (10FR) and a high-pressure accumulator (24FR) corresponding to a front-right wheel (4FR). As a result, the pulsation can be dispersed, and suppressed.
