Abstract
Abstract A fluid delivery and vapor recovery arm especially for dispensing gasoline or other volatile liquids and collecting their evolved vapors, having a combined fluid delivery-vapor recovery head assembly mounted on the distal end of the arm''s outer boom section. The outer boom section includes vertically spaced and generally parallel conduits, one for fluid delivery and one for vapor return, interconnecting the head assembly and the arm''s inner boom section through swivel joints in such manner that vertical orientation of the head assembly is ensured for any attitude of the outer boom section. The head assembly includes an annular dome seat that engages a collar to close off the lower end of a vapor return conduit until the head is seated in a container hatch. The arm will deliver fluid to a container only when the head is properly seated in the hatch, and only when the fluid in the container is below a certain level. The arm further includes a control valve assembly having a diaphragm valve that controls a fluid delivery valve operated by air pressure. A venturi-type mechanism, also considered to be an aspirator device, functions to actuate the diaphragm valve when the liquid in the container rises to a predetermined level, causing this valve to shut off air pressure to the fluid delivery valve, which delivery valve then automatically closes. A contact valve in the control valve assembly directs air pressure to the fluid delivery valve only when the dome seat is properly positioned in the hatch thus causing the delivery valve to open, and the diaphragm and contact valves cooperate in a unique manner to prevent the delivery valve from opening accidentally.
