摘要

The controller has control cylinders subjected to the pressure from a pressure source (43,44) via a controllable valve (22,26) and an electric controller for driving the controllable vale. The valve, at least part of the pressure source and the electric controller can be combined into a unit. The valve, at least part of the pressure source, the electric controller and the control cylinders can be combined into a unit (111).
