FIELD: physics.
SUBSTANCE: air bubble formed after discharge from a pneumatic radiator is blown out by reducing its volume and changing its shape. At the moment of overexpansion of the air bubble, when pressure inside the bubble becomes less than the pressure outside, water outside the bubble is sucked into the bubble due to the less pressure inside the bubble. The pulsation dampener is in form of one or more cylinders having one end closed by a check valve lying inside the bubble and the other end outside the bubble.
EFFECT: high probing resolution.
