A fuel dispensing nozzle has a body defining a fuel supply passage and a vapor return passage each having a control valve operated by a hand actuated lever pivotally connected to an axially movable tubular member retained by a diaphragm actuated clutch. A fuel spout extends from the body and is surrounded by an annular plastic socket assembly to define therebetween a vapor return passage. The socket assembly includes a first socket member supporting an annular vapor seal for engaging a fuel tank fill tube. The first socket member is supported for universal free tilting movement by a second socket member supported by the body for axial movement. The second socket member supports a pin connected to a crank arm for blocking operation of the clutch, and an annular flexible cover surrounds the socket assembly to protect the socket members which provide unrestricted flow of fuel vapors.

What is claimed is: 1. A dispensing nozzle assembly adapted to be used with a vapor recovery fuel dispensing system including a flexible hose defining a liquid fuel supply passage and a vapor return passage, said nozzle assembly comprisinga nozzle body having a fuel supply passage and a vapor return passage,a fuel supply spout extending from said body and forming an extension of said fuel supply passage,a manually actuated fuel control valve within said fuel supply passage,a swivel socket assembly connected to said body and surrounding said fuel supply spout to define therebetween a vapor return passage connected to said vapor return passage within said body,said socket assembly including a substantially rigid annular first socket member supporting an annular resilient sealing member adapted to engage a fuel tank fill tube,a substantially rigid annular second socket member connected to said body and supported for axial movement relative to said body between retracted and extended positions, andsaid first and second socket members having mating and sliding surfaces providing for universal tilting movement between said socket members while maintaining said vapor return passage within said socket members.
