1. A nozzle for dispensing fluid comprising:
- a nozzle body including a spout and fluid path through which fluid to be dispensed is flowable;
an actuator configured to detect when said spout is sufficiently inserted into a fluid receptacle;
a shut-off device configured to selectively terminate or prevent fluid dispensing through said fluid path; and
an interlock operatively coupling said actuator to said shut-off device, said interlock including a slider that is operatively coupled to said actuator and a pivotable arm that is operatively coupled to said shut-off device, and wherein said slider is slidable along said pivotable arm.

Abstract
A nozzle for dispensing fluid including a nozzle body having a spout and fluid path through which fluid to be dispensed is flowable. The nozzle includes an actuator configured to detect when the spout is sufficiently inserted into a fluid receptacle, and a shut-off device configured to selectively terminate or prevent fluid dispensing operations through the fluid path. The nozzle further includes an interlock operatively coupling the actuator to the shut-off device. The interlock includes a slider that is operatively coupled to the actuator and a pivotable arm that is operatively coupled to the shut-off device, and the slider is slidable along the arm.

25. A nozzle for dispensing fluid comprising:
-
a nozzle body including a spout and fluid path through which fluid to be dispensed is flowable; an actuator configured to detect when said spout is sufficiently inserted into a fluid receptacle; a shut-off device configured to selectively terminate or prevent fluid dispensing through said fluid path; and an interlock operatively coupling said actuator to said shut-off device, said interlock including a slider that is operatively coupled to said actuator and a pivotable arm that is operatively coupled to said shut-off device, and wherein said slider is slidable along said pivotable arm, wherein said actuator is configured to be in an extended position when said spout is not inserted into said fluid receptacle, wherein said actuator is configured to move to a retracted position when said spout is sufficiently inserted into said fluid receptacle, and wherein the actuator further includes a pair of pushrods configured to at least partially transmit said movement of said actuator to said interlock. - View Dependent Claims (26)

27. A nozzle for dispensing fluid comprising:
-
a nozzle body including a spout and fluid path through which fluid to be dispensed is flowable; a shut-off device configured to selectively terminate or prevent fluid dispensing through said fluid path; and an interlock including an actuator configured to detect when said spout is sufficiently inserted into a fluid receptacle, said interlock being operatively coupled to said shut-off device, wherein said interlock includes a slider having an angled or curved engagement surface and wherein said actuator is operatively coupled to said slider, and wherein said interlock further includes a pivotable arm in operative slidable contact with said engagement surface. - View Dependent Claims (28, 29)

30. A nozzle for dispensing fluid comprising:
-
a nozzle body including a spout and fluid path through which fluid to be dispensed is flowable; a shut-off device configured to selectively terminate or prevent fluid dispensing through said fluid path, said shut-off device including a diaphragm and being configured to terminate or prevent fluid dispensing when liquid is detected at at least part of said spout; and an interlock operatively coupled to said shut-off device and including an actuator configured to detect when said spout is sufficiently inserted into a fluid receptacle, said actuator being configured to be in an extended position when said spout is not inserted into said fluid receptacle, and wherein said actuator is configured to be in a retracted position when said spout is sufficiently inserted into said fluid receptacle, wherein said interlock includes a slider having an angled or curved engagement surface and said actuator is operatively coupled to said slider, and wherein said interlock further includes a pivotable arm configured to be in operative slidable contact with said engagement surface and operatively coupled to said diaphragm, and wherein said angled or curved engagement surface presents to said pivotable arm a portion having an effectively increased thickness in a direction perpendicular to said diaphragm when said actuator moves from said extended position to said retracted position to thereby move said diaphragm. - View Dependent Claims (31)
