Pneumatisch betätigtes Mehrwegeventil und Kältemaschine mit Mehrwegeventil

摘要

The invention relates to a multiway valve, in particular for use in the refrigerant circuit of a refrigeration unit. Said valve comprises a housing (10) with several inlets and outlets (11, 12, 13) and a chamber (16) with several seats (20) that are respectively allocated to one inlet or outlet (12, 13). A closing organ (19) is allocated to each seat (20). The closing organs (19) are coupled to a cell (1) that can be expanded and compressed by the action of a control pressure, in order to block or release the allocated seat (20) in accordance with the compression or expansion of the cell (1). A gas generator and absorber can be housed in the cell (1) for generating the control pressure.
