Abstract

The invention relates to a system for refilling a subsea motor cooling circuit, which cooling circuit comprises a cooler exposed to the surrounding body of water, and which system comprises a refill source, a line connection between the refill source and the cooling circuit and a valve in the line connection for metered refilling of the cooling circuit. The invention is characterised in that the metering valve comprises a housing (8, 9) having a first (11) and a second (12) chamber, which are separated from one another by a bellows (10), where the first chamber (11) has an inlet (13) connected to the refill source via a non-return valve (14) and a valve-controlled outlet (16) connected to the cooling circuit. The second chamber (12) is filled with liquid and accommodates a liquid-carrying heat exchanger (18) having an inlet and an outlet, where the outlet (22) is connected to the cooling circuit downstream of the cooler, and the inlet via shuttle valve (20) can be connected to the cooling circuit upstream of the cooler (6), directly or via a second cooler (19) exposed to the body of water, and which is throttle-connected (21) to the cooling circuit.

The invention is characterized in that the metering valve comprises a housing (8, 9) having a first (11) and a second (12' chamber, which are separated from one another by a bellows (101, where the first chamber (11) has an inlet 13' connected to the refill source via a non-return valve (14) and a valve-controlled outlet (16) connected to the cooling circuit. The second chamber (12, is filled with liquid and accommodates a liquid-carrying heat exchanger (18) having an inlet and an outlet, where the outlet (22) is connected to the cooling circuit downstream of the cooler, and the inlet via shuttle valve (20) can be connected to the cooling circuit upstream of the cooler (6l, directly or via a second cooler (19) exposed to the body of water, and which is throttle-connected (21) to the cooling circuit.
