摘要：
The invention relates to an exchange and/or scavenging device for a circuit comprising at least one hydraulic motor. The inventive device consists of an exchange valve (24) comprising an opening-control chamber which can be connected to a main conduit (12, 14) of the circuit, and a closing-control chamber. The pressure in said chambers enables the movement of the mobile member of the exchange valve to be controlled in order to connect or not the aforementioned main conduit, which is connected to the valve, to a depressurised tank. The device also comprises a control valve (46) which is controlled according to at least one control parameter representing a circuit condition other than the pressure in the main conduit to which the valve (24) is connected, in order to connect the closing-control chamber to the depressurised tank or to isolate the chamber from the tank.
