Device for regulating the liquid phase of a heat-engine cooling circuit, in particular for an automobile

摘要

The device has envelope connecting units (7) arranged in a plane parallel to a joint plane (9) of half shells (2, 3) between each other, and provided circumferentially around the perimeter of an envelope (1). Each connecting unit is engaged with a complementary connection unit (11) carried by a connection piece (10). The connecting units are selectively activated according to an angular position of the connection piece around the envelope for connection of the connection piece to the envelope at any location in the periphery of the envelope.
