Abstract

1,264,188. Valves. DOUBLE A PRODUCTS CO. No. 48819/69. Heading F2V. Relief valve comprises a valve member 42 and seat 14, the valve member being loaded by a pair of Belleville type springs 44, 46. An abutment 56 for the springs is adjustable by a differential screw device 68, 70. In a modification, the abutment is adjustable by a screwoperated wedge (160) Figs. 4-6 (not shown).
