Abstract:
A spray nozzle (10) for a window or glass washing system, comprising: a nozzle element (24) in which at least part of a flow conduit (36) is formed by an elastic hoselike part (26, 28), wherein said hoselike part (26, 28) closes the flow conduit (36) and wherein, under the influence of a washing fluid pressure, said hoselike part (26, 28) widens elastically and uncovers the flow conduit (36), wherein a mandrel is disposed on an end of the hoselike part, wherein the hoselike part (26, 28, 30), with its flow conduit (36), rests tightly in a pressureless state, with an initial tension, on the mandrel (18, 20, 22, 54, 56), wherein the hoselike part (26, 28, 30) on the end having the mandrel (18, 20, 33, 54, 56) forms a spray hole, and wherein, under said washing fluid pressure, the hoselike part is at least partially lifted from the mandrel, thereby allowing a flowthrough of said washing fluid.
