Estimating the term…
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.
An angularly adjustable pipe joint with a valve, comprising two releasably interconnectible half shells that are adjustable relative to each other in a meridian plane about an axis perpendicular to said plane, each of said half shells having a pipe boss thereon that has an axis, the axis of at least one of said pipe bosses being out of coincidence with the first-mentioned axis, a rotatable blocking and regulating element disposed within the two half shells and having a bore therethrough out of registry with the first-mentioned axis, and means for rotating said element within said half shells about the first-mentioned axis, one end of said bore communicating with said boss of one of said half shells in all positions of said rotatable blocking and regulating element and said one half shell relative to each other, the other end of said bore communicating with said boss of the other of said half shells in less than all of the positions of said rotatable blocking and regulating element and said other half shell relative to each other.
