Abstract

882,970. Fluid actuation of switches. LE CORVOISIER, P. F. May 23, 1960 [May 27, 1959], No. 18173/60. Class 38 (5). [Also in Group XVIII] A low-level alarm device particularly for a motor cycle fuel tank comprises a float-operated switch housed within a chamber 5 enclosed by the depending skirt 4 of a plug 2 forming the filler cap for the tank and a warning lamp or acoustic signal actuated by the switch. The chamber 5 is closed at the bottom by a fluidtight diaphragm 8 the edge of which is clamped between a centrally-apertured metal plate 7 and a metal cap 9 and secured to the rim of the skirt 4 by screws 6. The diaphragm carries a contact 14 screwed into a support 15 from which a float 17 is suspended by a chain or cable 16. The weight of the diaphragm, the members 14, 15 and the connector 16 is balanced by a spring 18 housed within the cap 9, so that the contact 14 is held away from the plate 7 which forms the fixed contact, and has a terminal post 10 whilst the float is supported by the liquid in the tank. When the liquid falls to a predetermined low level, the float becomes suspended from the diaphragm and the added weight causes the latter to move downwards until the contacts 14, 7 engage to complete the alarm circuit.
