AbstractThe invention relates to a mechanically operated three- or multi-port valve, which is adjustable with less mechanical work than conventional mechanically operated three- or multi-port valves. This is made possible by two separation devices (2, 2a, 2b) arranged one behind the other, each with several outlet recesses (1). Where the recesses (1) of the various separators (2, 2a, 2b) overlap, there are openings (3). Since several outlet openings (3) can form for at least one, but preferably several or all of the inlet/outlet openings (5a to 5d) of a valve, the travel ranges are significantly shortened compared to other three- or multi-port valves, which reduces the mechanical work required for adjustment. As a result, much weaker and thus smaller drives can be provided for operating the actuator (6). The attachment point in the valve and possible embodiments of the actuator (6) also support adjustment of the valve according to the invention with little mechanical work.
