FIELD: smoking accessories.
SUBSTANCE: group of inventions relates to personal evaporation devices, such as electronic cigarettes. Valve for electronic cigarette, comprising a valve comprising a first portion, a second portion and a biasing member configured to apply a biasing force between the first portion and the second portion. Valve may be actuated between open position and closed position in accordance with relative angular position of first part relative to second part. Valve further comprises an actuator with a variable length, comprising a shape memory alloy configured to vary its length under the effect of heat, which is configured to create a force which counteracts biasing force from the biasing part. Valve position changes when actuator force exceeds displacement force.
EFFECT: improved control of fluid medium in electronic cigarette.
