Pipe switch with spherical plug

摘要

The tubular switch has a plug (6) with a spherically corrugated circumferential surface and outlets for at least one through channel. The plug can turn round an axis (10) in a casing (1, 2) which has one input aperture and two output apertures. The plug consists of a spherical layer inside a ball volume bounded by a major circle (8a). The outlets of the through channels are bounded by ellipses in a projection along an imaginary line between the outlet surfaces.
