Rotary valve and heat pump

The invention relates to a rotary valve comprising a supply portion (6b, 19) with a plurality of stationary separate feeds (6c, 19a) for a plurality of streams of a fluid and a discharge area at a particular same plurality of stationary separate outlets (6d, 17a) for the streams of fluid, between the feed region (6b, 19) and the discharge area a shift range with a rotatable about an axis switching member (16, 31, 24) is provided, in a first position of the switching member (16), the plurality of leads ( 6c, 19a) with the plurality of outlets (6d, 17a) is connected in a first mapping, and wherein (in a second position of the switching element 16), the plurality of leads (6c, 19a) with the plurality of outlets (6d, 17a) is connected in a second mapping, wherein the switching member (16) axially traversed by a plurality of the fluid streams in the direction of the rotational axis, moved along with the switching member opening of Lu Ungen (16a) comprises, cover over a plurality of fixed, axially directed openings (19a) alternating in the course of rotation of the switching member (16) whereby the different allocations of the leads (19a) to the outlets (17a) by the changing overlaps the axially directed openings (16a, 19a) take place.
