Abstract

1,070,462. Radiator shutters. VARIVANE CO. Ltd. July 24, 1964 [July 26, 1963; Nov. 25, 1963], Nos. 29695/63 and 46417/63. Heading F4S. [Also in Division G1] A radiator shutter mechanism comprises pivoted shutters operated by a link 9, a spring 17 acting on the link 9 to close the shutters by way of a member (11, Fig. 7), a temperature responsive actuating element 10 to move the link 9 to open the shutters against the action of the spring 17, a second temperature responsive actuator, operating at a higher temperature than the first, to operate a release mechanism for the anchorage of the spring 17 and a second spring 21, weaker than the spring 17 acting on the link 9 to open the shutters when the release mechanism has been operated. The mechanism thus provides a " fail-safe " arrangement for the shutters. In one arrangement (Fig. 1) the shutters are operated from the link (9) by pivot rods (8) and the temperature responsive element (10) preferably a wax capsule element, is disposed in a chamber through which the cooling water which also passes through the radiator, flows. In Fig. 5 the upper end of the spring M is shown anchored to a pin 18 held in a housing 29 by a solenoid plunger 19 engaging a recess therein. In the event of failure of the element 10, the shutters 6 remain shut and the temperature of the cooling water rises. When it reaches a predetermined level the second temperature responsive element 25 actuates a switch 26 in the solenoid circuit to release the pin 18 and thus the tension in the spring 17. The shutters will then open under the action of the spring 21. In an alternative arrangement (Fig. 7) the spring (17) is secured to a pin (66) held by a ball (67) on a plunger (58). A second temperature responsive element acts on the plunger (58) so than when the temperature rises due to failure of the element (10) the plunger (58) is moved to bring a peripheral recess (59) thereon in line with the ball (67) thus releasing the pin (66). The connection between the plunger (58) and element (50) may be adjustable in length to adjust the temperature at which the pin (66) is released.
