Abstract
A multi-way valve, in particular for use in the refrigerant circuit of a refrigeration unit, includes a housing with several inlets and outlets and a chamber with several seats that are respectively allocated to one inlet or outlet. A closing member is allocated to each seat. The closing members are coupled to a cell that can be expanded and compressed by the action of a control pressure to block or release the allocated seat in accordance with the compression or expansion of the cell. A gas generator and absorber can be housed in the cell for generating the control pressure.
