Abstract
A mechanism for multiplying rotation. The mechanism includes two armatures of differing lengths which rotate about different centers of rotation. The armatures are coupled together such that a rotation of one armature will produce a multiplied rotation in the other armature. The multiplying mechanism has particular application with a valve assembly of the type used in self-contained sanitary systems of recreational vehicles. The valve assembly includes a seal element having a sealing lip directed toward generally inward and downward of a fill opening a valve blade in the holding tank. The sealing lip terminates in a downwardly and outwardly oriented flange. The valve blade is actuatable through two movements. The first movement moves the valve blade generally vertically into and out of engagement with the seal element. The second movement moves the valve blade generally horizontally to a position out of registry with the fill opening.
