Abstract (en)

The hydraulic device comprises a first chamber (10), a second chamber (12) with associated liquid-level sensor means (14), and a first siphon-shaped duct (16) connecting the first chamber (10) to the second chamber (12) and having a first branch (18) in communication with the first chamber (10), a second branch (20) in communication with the second chamber (12), and an intermediate portion (22) connecting the first branch (18) to the second branch (20). At least one cross-section (24) of the intermediate portion (22) is constricted - preferably by at least 50% - in comparison with the cross-sections of the first and second branches (18, 20). <IMAGE>
