Claims
- 1. A vapor recover, fuel dispensing nozzle comprising
- a nozzle body,
- a spout projecting from the downstream end of the nozzle body,
- an adapter received in a bore in the downstream end of the nozzle body, and secured therein in predetermined angular relation thereto,
- fuel passageway means extending from an inlet end of the nozzle body, through and including a bore in the adapter, to a discharge end of the spout,
- vapor return passageway mean, including a portion extending lengthwise of the spout and a portion defined at least in part by the adapter,
- means for mounting the spout on the nozzle body in projecting relation from the downstream end of the nozzle body,
- said spout comprising
- an inner tube defining fuel passageways means through the spout, and
- an outer tube defining, in combination with the inner tube, the vapor return passageway means of the spout,
- said inner and outer tubes being joined in fixed angular relation, with the distal end portions of said tubes being angled downwardly from their upstream portions,
- said mounting means including means for clamping the outer tube in sealed relation to the adapter and for providing a sealed connection between the inner tube and the bore of the adapter,
- characterized by
- means for establishing a predetermined angular relation between the inner tube and the adapter to thereby establish a desired angular relation between the spout and the nozzle body, and
- further characterized in that
- the means for establishing a predetermined angular relation between the inner tube and the adapter bore comprise
- interfitting notch and lug means at the upstream end of the inner spout tube, and
- the means for providing a sealed connection between the adapter and the inner tube comprise
- a counter bore opening on the downstream end of the adapter,
- a backup ring disposed outwardly of the bottom of the counter bore, and
- a sealing ring disposed between the backup ring and the bottom of the counterbore,
- said backup ring forcing the sealing ring into the counter bore when the inner tube is mounted in sealed relation to the adapter bore.
