Periodical Spring

When the outlet tube of the reservoir is siphon-shaped, the discharge of the spring becomes periodical. The spring continues to discharge its waters for a time, and then stops flowing, even during wet weather. After a certain interval it again charges. The times during which the spring continues to discharge are always practically the same. Hence the spring is called a periodical spring.
