摘要： A magnetically actuated valve for an electric water-heater comprises a tubular valve body. Said body has two sections with different inner diameter from each other, between the two sections, there is a step with a through hole at the center thereof, a recess housing a flaky spring ring is formed in the inner wall of the section with larger diameter, and between the step and the spring ring is a floater shaped as formula (I) -symbol and with a through hole, and the floater protruding portion is inserted into a ring-like magnet. A groove is formed in the outer surface of side body, in the groove is mounted a magnetic reed switch with an electromagnetic induction mechanism, with output end is connected to a control panel of the water-heater. This valve can control the flow and circuit synchronously and is of simply structure and high sensitivity for controlling.

摘要： The invention relates to a device (10) for supplying a hydraulic consumer with pressure means, comprising a pressure generator (14), an electromotor (16) and a reservoir (18). A level switch (40) is located on the reservoir (18) for supplying the electromotor (16) with voltage according to the level and hereby preventing the intake of air. The invention provides that the level switch (40) is anchored on the reservoir (18) in such a way that the two components can move in relation to each other, in order to avoid any dependency of the switching threshold of the level switch (40) on the tolerances and expansion of the parts. The level switch (40) also interacts with a prestressed component (56) that ensures that the level switch remains resting on the bottom surface of the reservoir (18).
