ABSTRACT:
A pipe joint that interconnects two pipe sections or bosses for relative rotational movement about an axis that is noncoincident with the axis of at least one of the bosses and preferably noncoincident with the axis of both of the bosses. A rotary valve member rotates about that axis and has a bore therethrough that does not coincide with that axis, although preferably that axis and the axis of the bore intersect in the plane of the joint between the pipe sections. A valve operator may be disposed either in the plane of the intersection of the pipe sections, or else along the axis of rotation of the blocking and regulating element, that axis being perpendicular to that plane. The angle between the axis of the bore and the axis of rotation of the blocking and regulating element, is greater than zero but less than 90.degree. and preferably about 45.degree.. The valve operator can be a ring or handle disposed in the meridian plane of the pipe sections, or an axially protruding knob.
