ABSTRACT:
A rotary valve of a multi-circuit type consists of an outer valve body with a cylindrical hole therethrough and an inner valve body rotatably inserted into the cylindrical hole of the outer valve body. The outer valve body is at a plurality of heights provided with outer fluid lines extending through the wall of the outer valve body to the cylindrical hole, and with fittings on its outer surface that connect to the outer fluid lines. The inner valve body has on its outer periphery annular passages made fluid-tight and communicated with respective outer fluid lines of the outer valve body when the inner valve body is inserted into the outer valve body. The inner valve body further has inner fluid lines that communicate one of the annular passages with a respective one of the fittings mounted around the flange of the inner valve body. To one or the other of the fittings on the outer and inner valve bodies are connected pipeways on the fluid inlet side or pipeways on the fluid outlet side. The multi-circuit type rotary valve is compact in size and excludes entanglements to its outer piping.
