Abstract

584,602. Pistons. BRITISH THOMSONHOUSTON CO., Ltd., and TUPPEN, E. B. Jan. 9, 1945, No. 774. [Class 122 (i)] [Also in Groups XXXII and XXXVII] In a fluid pressure operated switch mechanism of the kind described in Specification 418,051, [Group XXXVII], the diaphragm is free from spring pressure when there is an absence of fluid pressure. A. diaphragm 17 responds to the pressure of fluid in a port 20 by compressing a spring 1 after lost motion as the diaphragm moves through a small space 22. A member 16, free to move in a space 19, transmits pressure from the diaphragm 17 to a cup 3 on the end of the spring 1 and prevents the latter from pressing on the diaphragm when it is inoperative, Fig. 3. Specification 533,169, [Group XXXVII], also is referred to.
