摘要： A ventilator opens and closes itself according to the temperature in its environment through the use of a bimetallic coil spring which acts through a drive element and linkage elements to open and close the louvers of the ventilator. The louvers are disposed in an air passageway that is defined by a housing, which defines a spring box to house the coil. The louvers are configured with an S-shaped cross section so as to provide positive engagement between the louvers when they are in the closed position. The drive element and a linkage element have rotation post with bifurcated flared heads that rotatably engage the louvers for simultaneous movement. A removable backframe has projecting tabs that fit into holes defined near the rear edge of the housing. The backframe has a closure surface for engaging a forward-extending free edge of the uppermost louver. The backframe also has a closure stop member that engages the lowermost edge of the bottom louver. The backframe has a louver rotation stop member that prevents the louvers from rotating beyond a certain point when opened. A front panel and a closure flap prevent the passage of air and light in the vicinity of the spring box. The backframe preferably is formed as a unitary structure of molded plastic. The housing, the spring box, and a collar surrounding the exterior of the housing preferably are formed as a unitary structure of molded plastic.

摘要： An improved foundation ventilator assembly including a housing in which united shutter elements are mounted for pivotal movement between an open and closed position to control air flow through the ventilator. Preferably, a thermally responsive spring is secured to one of the shutter elements to cause pivotal movement of same with changes in ambient temperature. The housing defines openings therein for the receipt of mounting means which are utilized to secure the ventilator assembly within a foundation or other wall opening. The mounting means includes a threaded element in threaded engagement with a pressure element, such that when the threaded element is screwed into the foundation or other wall surrounding the opening, force is applied against the ventilator assembly or at least partially absorbed by the pressure plate. A removably secureable rear cover or screen may also be provided to close the rear of the ventilator assembly.

摘要： An automatic temperature responsive ventilator including a housing having side walls defining an air passageway and an openwork grid across the passageway. At least one shutter is mounted within the housing, with one end of one shutter element being associated with a bimetallic spring, the inner end of which is received within an opening in one housing side wall. An outer end of the spring is secured to the shutter. A size-adjustable installation device includes a threaded portion which engages a threaded opening in the housing or in a member held non-rotatable relative to the housing. One end of the threaded portion is integral with a non-threaded distal portion having a diameter less than the diameter of the threaded portion and carrying thereon the small diameter end of a conically shaped compression spring. Variations in ambient temperature cause the shutter element to open and close automatically.

摘要： A ventilator is selectively configured so that it can automatically open and close its louvers according to the temperature in its environment or have its louvers manually positioned in either the open or closed orientation. The louvers are disposed in an air passageway that is defined by a housing. A bimetallic coil acts through a drive element and a linkage element to automatically open and close the louvers of the ventilator. A pair of override members have respective handles accessible to the user. Manipulation of the override members enables the user to override the automatic drive element to manually open and close the louvers.
