<p>The manually-operated fluid-sprayer has a passage (45) formed in a cap and leading to the exterior. The inner end of the passage is connected via a pressure-operated valve to a chamber, the latter in turn connected by a further valve to a nozzle. One wall of the chamber is elastic, while a rigid tube is connected to it via a lateral jet, and connects the nozzle to the inner end of the passage. The tube can be straight and the chamber can be elastic and of pear shape.</p> |
