Abstract

Improved hydraulic connector-disconnector device, intended to be interposed between a pump and a pressure accumulator to maintain the pressure of the liquid in the latter between two determined values, which comprises a non-return valve in an accumulator supply duct and, above this valve, a derivation of the pump drive towards the suction comprising a distribution member subjected to the opposite actions of a spring and the pressure that prevails downstream of said anti-return valve, these actions tending, respectively, to requesting said distribution body in the closing position and in the opening position of said derivation.
