Abstract

1,077,466. Fluid actuation of switches; thermal switches. TEXAS INSTRUMENTS Inc. July 23, 1964, No. 29650/64. Heading H2B. A pressure-responsive device 11 is made by securing a permanently deformable diaphragm 20 between two casing parts 12, 14, applying a controlled fluid pressure into cavity 18 through aperture 138 to permanently stress and deform the diaphragm to a desired configuration, which may or may not be snap-acting, and locating, a motion-transfer pin 140 for reciprocable movement in aperture-138, whereby movement of diaphragm 20 in response to predetermined pressure changes in cavity 16 causes pin 140 to actuate an electric switch, the diaphragm returning to its initial position upon release of the pressure applied through port 30. The diaphragm may be bimetallic (Fig. 4, not shown), and the device is then responsive to a combination of predetermined pressure and temperature conditions, and can be adapted to respond solely to predetermined temperature conditions or predetermined pressure conditions. Screw member 130 is adjustable, and casing part 12 may carry a second adjustable abutment (150) for the diaphragm, (Figs. 3, 4, not shown). The motion transfer pin (340) may actuate a snap-acting disc (370) to actuate a switch (Figs. 5, 5a, 6, not shown), the position of disc (370) being adjustable. Casing parts 12, 14, and diaphragm 20 may be of materials having different coefficients of thermal expansion so that the device is responsive to a predetermined combination of pressure and temperature conditions. The switch actuated by the device is normally open, normally closed or changeover.
