Abstract

A valve system (12) for control of walking cylinder (10) of powered support section includes the first pressure supply (PA) and the second pressure supply (PB). Besides, system includes opened check valve (14) that is provided between pressure supply (PB) and connecting hole (B), and damping valve (18) equipped with throttle (16). At that, damping valve is installed between other pressure supply (PA) and connecting hole (A) of the cylinder.
