Abstract

A device for providing a synchronized fluid supply to and fluid evacuation from at least two linear hydraulic motors (9a, 9b) comprises a pumping arrangement including for each of the hydraulic motors a particular hydraulic cylinder pump (16a, 16b) such that each of these pumps fluidly co-operates with only one motor, parts (17a, 17b) comprised in the pumps and adapted to, on movement thereof, cause fluid supply to and fluid evacuation from the motors being interconnected by a linearly movable element (18) of a driving arrangement. The hydraulic pumps have openings which enable communication between the working chambers of the pumps and a hydraulic fluid reservoir when said working chambers are substantially maximal but which are automatically closed off when the volume of the working chambers is reduced.
