Abstract
The thermally responsive valve device is comprised of a body having three passages therein, the first of which is adapted to be conected to a vacuum source while the second and third passages are each adapted to be connected to a suitable fluid operated device. The first passage is in constant fluid communication with two spaced apart fluid chambers within the body while the second and third passages are in selective communication with said chambers respectively. A valve member is located in each chamber for controlling communication of the second and third passages with their respective chambers. A pair of snapacting bimetallic disks are mounted in spaced relation within a third chamber in alignment with each other and each valve member. An operating rod is disposed in operative engagement between one of said disks and one of said valve members and a hollow tubular sleeve concentric with said rod is disposed in operative engagement between the other of said disk and the other of said valve members. A spring is operatively associated with each valve member for biasing the respective valve member toward said bimetallic disk to allow communication between said first passage and said second and third passages.
