<p>Apparatus for converting a pressurized, low continuous flow of a fluid into an intermittently pulsing, high flow, which comprises an elastic sleeve which closely surrounds a rigid inserted component held in a fixed location at its ends by parts closely surrounding the inserted component with a larger external diameter, the said inserted component having an entry for the fluid and an exit for the fluid in the form of cylinders plugged at one end and perforated on their periphery, the said perforations being closely surrounded by the said elastic sleeve, thus creating valves which respond to the pre-set pressure, and which are normally closed, eliminating the passage of a fluid through the said perforations and, when the pressure of a fluid at the entry to the apparatus is sufficiently high, to force the said elastic sleeve to expand; the fluid then enters a space which surrounds the inserted component and is enclosed inside the said elastic sleeve, and when the volume and the pressure of the fluid inside the said space increase, it increases the pressure inside the said space and forces the elastic sleeve at the exit of the said space to expand, the fluid then flowing from the space via the perforations in the cylinder in the exit section of the said inserted component and, owing to the drop in pressure created at the exit from the said space, it increases the pressure inside the said space, causing the additional expansion of the elastic sleeve, thus creating a larger opening at the exit from the said space and causing the fluid to be ejected from the said space via the said perforations and the exit from the apparatus at a high flow, whilst the fluid continues to flow inside the said space via the entry of the device at a low flow, the fluid entering the device with a low, continuous flow being, as a consequence of this, ejected from the device at an intermittently pulsing, high flow.
