Abstract
A suction nozzle adapted for use in a suction cleaning device, such as an automatic swimming pool cleaner, includes a body having a throat extending from an inlet at one end of the body to an outlet at an opposite end of the body. The body itself is split longitudinally into a plurality of discrete body portions to form the throat of the nozzle. One body portion is movable relative to the other body portion, whereby the throat automatically expands in response to the relative movement of the body portions. The resulting expansion of the nozzle allows substantially unrestricted passage of large foreign objects through the throat during the operation of the suction cleaning device.
