Beschreibung
Zusammenfassung:	The invention relates to a combination heating and cooling valve assembly having a housing with horizontally aligned inlet and outlet ports and a second outlet port which opens downwardly at right angles to the other two ports. A movable valve plate having an aperture and upper and lower closure portions cooperates with the first outlet port. The valve plate has two closed positions corresponding to heating and cooling operations with either the upper or lower closure portion thereof covering the outlet port. A valve rod unit connected to the valve plate has a temperature responsive expansible link for lengthening and shortening the effective length of the rod unit depending on whether the valve assembly is controlling a cooling or heating medium. The expansible rod link is accessible to the heating or cooling medium which supplies the heat or cold for operating the link.
