  • Patent number: 9416890
    Abstract: A flow control valve (1) and a method for assembling a flow control valve (1) are disclosed. The flow control valve (1) comprises a first housing part (2) and a second housing part (3) attached directly to each other, in such a manner that the first housing part (2) and the second housing part (3) form a substantially closed housing. The first housing part (2) defines a first flow section (4), a second flow section (5), a connecting port (6) fluidly interconnecting the first flow section (4) and the second flow section (5), and a valve seat (7) arranged at the connecting port (6). The flow control valve (1) further comprises a frame part (9) arranged in an interior part of the housing formed by the first housing part (2) and the second housing part (3), the frame part (9) having mounted thereon a valve element (10, 13) arranged movably relative to the valve seat (7), a moving mechanism, e.g. including a spindle (12), for moving the valve element (10, 13), and an actuating mechanism, e.g.

  • Patent number: 4139150
    Abstract: 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.
