Abstract

1,273,330. Spraying powders. ATLAS COPCO A.B. 21 April, 1969 [26 April, 1968; 14 Jan., 1969; 27 March, 1969], No. 52343/71. Divided out of 1,271,731. Heading B2L. Means for regulating the output of a mixture of powder and air from an injector 95 of a spraying plant comprises a trigger 82 which controls two valves 84, 85, air supply valves 89, 90 controlled by the valves 84, 85 and check valves 93, 94 which feed the air to the injector 95. When the trigger 82 is only partially depressed valve 84 only is opened and air passes from supply bore 86 through a pressure reducing valve 92, supply valve 89 and check valve 93 to the injector. When the trigger is further depressed both valves 89, 90 are opened. The control system can be used in a spraying apparatus which is essentially similar to that described in Specification 1,271,731 except that instead of the turnstile valve a butterfly valve is provided at the base of the hopper.
