摘要 |
<p>The invention relates to a vacuum cleaner comprising a pressure-sensitive device for indicating the degree of suction prevailing in the suction tube means of the cleaner. The device is arranged in the suction tube means and comprises a pressure-sensitive element, such as a diaphragm, to which an indicator is coupled. The invention provides a construction by which the pressure difference between two different locations in the suction tube means is transmitted to the pressure-sensitive element. The results in a displacement of the indicator which is a measure of the air velocity and hence an indication of the degree of suction prevailing.</p> |
