    摘要: A ball bearing swivel connectable between the output end of a fuel dispensing hose and the input end of a fuel dispensing nozzle to allow multi-plane rotation of the nozzle The swivel includes three segments, a nozzle fitting, a midsection, and a hose fitting. The end segments are joined to the midsection by ball bearing races which allow each segment to rotate 360° relative to the adjacent segment. The ball bearing races are positioned between a first and second O-ring seal to prevent dust or dirt accumulation and fuel leakage. The ball bearing races allow rotation of the swivel under increased fluid pressure conditions.

    摘要: A fuel nozzle assembly for dispensing fuel from a source to a container includes a body defining a fuel flow path and a vapor recovery path. The nozzle includes a venturi valve in the fuel flow path which defines a venturi port and a diaphragm valve positioned in the vapor recover path, The diaphragm valve has a control section having a control port which is in fluid communication with the venturi. The diaphragm valve is normally spring biased closed. When gas flows through the venturi and over the venturi port, it creates a vacuum in the diaphragm control section sufficiently strong to open the diaphragm valve so that recovered vapors may be returned to a source of fuel, or other collection area, such as an underground storage fuel tank.
