Abstract

1,128,967. Valves. BIRFIELD ENG. Ltd. 18 Sept., 1967 [22 Sept., 1966], No. 42366/67. Heading F2V. [Also in Division B8] A controller for the air supply to a pneumatic load balancing hoist (see Division B8) comprises a main air passage between a supply 60 and an outlet 58A to the hoist, and including a manually adjustable main regulator 66 which is controlled by pilot air pressure in a chamber 72 acting on a diaphragm 71. The pilot air taken from the supply 60 is controlled by a regulator 70 and setting screws 76, 78 and passes through a line 80 to a load responsive relief valve in the hoist loading rope. The outlet 58A to the hoist is controlled by a check valve 68 operated by the main air passing the regulator 66.
