Abstract

The device for heating liquid generates steam, receives a fluid in liquid form at its inlet, and ejects the fluid heated up or in gaseous form at its outlet. The device includes a heater positioned inside a sleeve having a longitudinal axis. There is a scraper that fits onto the heater to scrape it the heater in case of movement along the longitudinal axis. A stopper fits snugly between the heater and the sleeve in order to stopper the passage. The scraper, the stopper, and a spring are configured so that an increase in pressure causes the scraper and the stopper to move along the longitudinal axis so that the stopper is shifted to a point where space between the heater and the sleeve allows fluid to pass, and a reduction in pressure causes a shift in the opposite direction by the spring.
