To prevent a defect in which a liquid is retained in a vicinity of a valley of a bellows part and particles such as impurities are accumulated. Provided is a valve including a valve element part and a diaphragm part that is coupled to the valve element part. The diaphragm part includes a base, a tip part, and a bellows part that couples between the base and the tip part. A wetted part in contact with the liquid at the tip part is formed in a cylindrical shape extending along a shaft line X. A lower end part of the bellows part is connected to the wetted part in a connection position CP coinciding with an outer peripheral surface of the wetted part. The valley of the bellows part is disposed in the connection position CP.

A motor vehicle air-conditioning line valve arrangement includes a line valve having an air-conditioning line body which is of substantially closed design in a transverse plane, and a fiber nonwoven arranged on an inside in the air-conditioning line body and having a nonwoven mat to which a large number of nonwoven fibers are fixed. The nonwoven fibers are fixed to the nonwoven mat at one end and configured to be electrostatically charged by the nonwoven mat. An electrical charge generator is electrically connected to the nonwoven mat and configured to electrostatically charge the fiber nonwoven, so that the electrostatically charged nonwoven fibers straighten toward a center of the air-conditioning line body in such a way that they close an open flow cross section of the air-conditioning line body.

A self-acting pressure activated drain valve includes at least one inlet configured to receive a fluid. A drainage passage delivers the fluid to at least one outlet where the fluid is expelled. The self-acting pressure activated drain valve further includes a flexible diaphragm configured to operate in an open position and a closed position based on a pressure. The flexible diaphragm is normally biased in the open position such that fluid is delivered from the at least one inlet to the at least one outlet via the drainage passage. The pressure, however, initiates the closed position such that air is prevented from flowing through the drainage passage.

An electronic cigarette includes a power supply device, an atomizer, a liquid storage structure, a fluid transportation device, a casing and a mouthpiece. The atomizer includes an electric heater and a liquid conduit. The electric heater is disposed around liquid conduit. The liquid storage structure includes a liquid container for storing cigarette liquid. The fluid transportation device includes an input channel in communication with the liquid container and an output channel in communication with the liquid conduit. The cigarette liquid is transferred to the liquid conduit through the fluid transportation device at a certain amount. Consequently, an atomized vapor is generated. The casing has an inlet in communication with the atomizer through an airflow chamber. The inlet and the airflow chamber form an airflow path for an airflow to pass through. The mouthpiece is located at an end of the casing and in communication with the airflow path.
