Abstract

The invention concerns a device for the control of several hydraulic circuits. An oscillating lever (1) operates several control pistons (3) in a control stage (5). Each of these operates one of the pistons (21) of a power stage (6), connected by hydraulic chambers (26) to the operating apparatus. Each control piston (3) forms a hydraulic regulator with transitional surfaces in the shape o fa truncated cone (16, 17) which moves the power stage via an aperture (18, Figure 2, not shown) and axial channel (19) to admit pressure to chamber (20). Applications: multiple hydraulic controls, mainly for civil engineering machines. <IMAGE>
