Abstract

862,563. Valves. FAIRFIELD SHIPBUILDING & ENGINEERING CO. Ltd. June 14, 1957 [June 15, 1956], No. 18572/56. Class 135. [Also in Group XXVI] A fuel valve 43 is actuated by a device 61 when the pressure in the chamber 73 falls below a predetermined value. The control valve 43 comprises a valve proper 64 carried by a stem 65 which has a hand wheel 66 and a screw-threaded portion 67 for hand operation and is lightly urged by a spring 68 to close against the seat 63. A nut 69, held against turning by a guide 70, is movable with the stem. A lever 77 pivoted onthe nut 69 and engaging a stop 79 is connected to a spring-loaded piston 74 of the device 61. When the pressure in the chamber 73 falls below a predetermined value, the spring 75 forces the piston 74 downwards and pulls the lever 77 away from the stop 79 and against the fulcrum 81. This releases the nut 69. The spring 75 then acts through the lever 77 to shut the valve and is assisted by the fuel pressure on the valve proper. The valve 43 must be re-set by operation of the hand wheel 66.
