Abstract

The chimney draft control valve has a baffle plate suspended inside a housing, between an inlet opening and a valve seat inside that housing. The baffle plate is suspended to a pivot axis for pendulum movement toward and away from the valve seat and for checking a draft in a chimney when a vacuum pressure in that chimney is high. A spring is affixed to the housing and to the baffle plate for controlling an amplitude of the pendulum movement of the baffle plate in moderate to strong wind conditions. A dampening device is affixed to the housing, to the baffle plate and to the spring for controlling a period and amplitude of the pendulum movement of the baffle plate and a free vibration in the spring.
