Abstract
A rotary valve for an adsorption heat pump may include a cylindrical valve body, arranged rotatably about a central axis in a predetermined rotation direction with an outer covering and two front plates. A plurality of counter-directional high temperature connections may be arranged on the outer covering for connecting a high temperature heat source. A plurality of counter-directional medium temperature connections may be arranged on the outer covering for connecting a medium temperature heat sink. A plurality of sorption module connections may be arranged on the front plates for connecting a plurality of corresponding sorption modules. A duct system may pass through the valve body for directing a fluid, and a throttle, integrated into the valve body, may be included for constricting a flow cross-section at a throttle site of the duct system. The duct system may include open ducts and closed ducts.
