Abstract

492,994. Valves. STEWART, F. C. June 17, 1937, No. 16802. [Class 135] A valve device for use in a heating and ventilating installation has two inlet ports 3, 4 for the admission of hot and cold air respectively and an outlet port 2 connected by a pipe 5 with a louvre or other point of delivery. An inner rotatable valve member 8 has two ports 9, 10 either of which may be made to co-operate with either or both of the ports 3, 4 while the other port co-operates with the port 2. The port 10 which is divided by a bar 12 is larger than the port 10. When the port 9 co-operates with the ports 3, 4, which is the winter position, a constant current of air with temperature control is obtained. When the port 10 co-operates with the ports 3, 4 a larger current of air without temperature control is obtained. The valve may be actuated by a lever directly connected to a spindle coaxial with the valve member or it may be operable from a remote point by chain or other gearing. Indicators may be fitted at the valve or at the remote actuating station. Specification 295,209, [Class 137], is referred to.
