A valve arrangement comprising a valve housing (10) which includes an inlet port (11) and two outlet ports (12, 13) for fluid flowing through said housing, a valve element (15) accommodated in a first valve space in the valve housing and movable between two end positions, wherewith said 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 said valve element (15), and further comprising a device (20 or 21 and 26, 47) for resetting said valve element between said positions. The valve element (15) is mounted on one end of a pivotal arm (18) and has the form of a vale 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 said further valve element connects one or the other of two fluid inlet ports (43) to a fluid outlet port (45) which is common to said fluid inlet ports.
L'invention concerne un agencement de soupape comprenant un carter (10) de soupape pourvu d'un orifice (11) d'entrée et de deux orifices (12, 13) de sortie permettant l'écoulement de fluide à travers ledit carter, un élément (15) de soupape logé dans un premier espace de soupape situé dans le carter de soupape et mobile entre deux positions terminales, ledit élément de soupape comprenant deux surfaces (16) conçues chacune pour agir conjointement avec un orifice de sortie de manière à fermer un orifice de sortie associé dans l'une et l'autre positions terminales dudit élément (15) de soupape. L'agencement de soupape comprend, en outre, un dispositif (20 ou 21 et 26, 47) destiné à repositionner l'élément de soupape entre les deux positions. L'élément (15) de soupape, qui est monté sur une extrémité d'un bras (18) pivotant, a la forme d'une plaque ou d'un disque de soupape présentant des surfaces (16) d'élément de soupape ayant une action alternée conjointe avec un orifice (12, 13) de sortie. Le bras (18) portant l'élément (15) de soupape est conçu pour entraîner mécaniquement un autre élément (42) de soupape, auquel il est d'ailleurs relié mécaniquement. Cet autre élément de soupape est logé dans un second espace de soupape séparé, entre les deux positions dans lesquelles l'autre élément de soupape relie l'un ou l'autre des orifices (43) de sortie de fluide à un orifice (45) de sortie de fluide commun aux deux orifices d'entrée de fluide.
