Abstract
Disclosed is an adjustable valve for liquid including a flexible tubular body having a first and a second end. The tubular body is capable of elongation along the longitudinal axis. Provided within the flexible tubular body is a substantially cylindrical rigid body the rigid having a diameter smaller than the inside diameter of the flexible tubular body to form a radial clearance between the rigid body and the inside surface of the flexible tubular body. Means for elongating the flexible tubular body along the longitudinal axis about the rigid body are also included, whereby elongation of the flexible tubular body reduces the radial clearance.
