Abstract (en)

[origin: EP2428685A1] The hydraulic circuit has a circuit breaker contactor (80) movable between a contactor position, in which first, second and third orifices (81, 82, 84) are connected with each other and a fourth orifice (83) is closed, and a circuit breaker position. The first and third orifices are closed, and the second orifice is connected to the fourth orifice to isolate an accumulation circuit from a supply line (10), in the circuit breaker position. The contactor is movable from the contactor position to the circuit breaker position when pressure in the accumulation circuit reaches a threshold value.
