Abstract
The device for controlling the movement of skips in machines for granular or powder and liquid treatment machines is of a type where the skip is separable from an overlying treatment chamber, to which it is sealingly couplable and which skip is rotatably supported by a horizontal-axis pivot (2) on a frame (3) mobile on wheels (4). The device comprises at least one hydraulic cylinder (5) provided with a piston (15) comprised between two chambers (25, 35), which cylinder (5) bears a rotating organ (45) coupled in rotation with the pivot (2). The two chambers (25, 35) are interconnected with an interpositioning of at least one regulation valve (6) which on command can regulate the flow of a hydraulic fluid in two directions and can also totally halt the flow.
