A valve arrangement including a valve housing (10) which includes an inlet port (11) and two outlet ports (12, 13) for fluid flowing through the housing. A valve element (15) is accommodated in a first valve space in the valve housing and movable between two end positions. The valve element includes two surfaces (16), each of which is adapted for co-action with a respective outlet port such as to close an associated outlet port in one and the other of the end positions of the valve element (15). A device (20 or 21 and 26, 47) for resetting the valve element between the positions. The valve element (15) is mounted on one end of a pivotal arm (18) and has the form of a valve plate or disc which includes valve-element surfaces (16) for alternate co-action with a respective outlet port (12, 13). The arm (18) carrying the valve element (15) is connected mechanically to and adapted to drive a further valve element (42), which is accommodated in a separate, second valve space, between two positions in which the further valve element connects one or the other of two fluid inlet ports (43) to a fluid outlet port (45) which is common to the fluid inlet ports.
A valve arrangement comprising a valve housing that includes an inlet port and two respective outlet ports for fluid passing through the housing, a valve element which is accommodated in a first valve space in the valve housing and movable between two end positions and which includes two mutually opposite surfaces, each of which is adapted for co-action with said outlet port such as to close said outlet port in a respective one and the other of the two end positions of said valve element, and resetting means for resetting said valve element between said positions, said valve element being mounted on one end of a pivotal arm, said valve element having a valve plate which includes mutually opposite surfaces for alternate co-action with said respective outlet port;
