The subject invention discloses a variety of different maintenance devices for use with a filling valve apparatus. The maintenance devices each include a movable component and a locking mechanism. An actuator of the locking mechanism is coupled to a caming section of the movable component for moving the movable component between a release position with a rim of the movable component spaced from fingers of the locking mechanism and an engaged position with the rim abutting the fingers. The fingers are wedged between the movable component and the filling valve apparatus when the movable component is in the engaged position for securing the device to the filling valve apparatus.

A maintenance device as set forth in claim 10 wherein said rim of said movable component includes an abutment engaging said inner surface of said fingers when said movable component is in said engaged position. 12. A maintenance device as set forth in claim 11 wherein said abutment includes a chamfer and said inner surface of said fingers includes a sloping surface complementary in configuration with said chamfer. 13. A maintenance device as set forth in claim 10 wherein said rim of said movable component includes a lip engaging said top of said fingers when said movable component is in said engaged position. 14. A method of mounting a maintenance device to a filling valve apparatus with the maintenance device having a movable component and a locking mechanism, the movable component having a peripheral rim and a caming section and the locking mechanism having a plurality of flexible fingers and an actuator coupled to the caming section, said method comprising the steps of: moving the actuator within the caming section to a release position; automatically moving the movable component during the movement of the actuator to the release position to space the rim from the fingers; positioning the maintenance device partially within the filling valve apparatus; moving the actuator within the caming section to an engaged position; and automatically moving the movable component during the movement of the actuator to the engaged position to abut the rim with the fingers and to wedge the fingers between the movable component and the filling valve apparatus for securing the device to the filling valve apparatus. 15. A method as set forth in claim 14 wherein the steps of moving the actuator within the caming section are each further defined as moving the actuator in a direction transverse to the movement of the movable component. 16. A method as set forth in claim 14 wherein said caming section includes a pair of slots and said actuator includes a pair of pins, and wherein said steps of moving the actuator within the caming section are each further defined as sliding the pins within corresponding slots. 17. A method as set forth in claim 16 wherein each of said slots define a ramp disposed between substantially flat top and bottom sections, and wherein the step of moving the actuator within the caming section to the release position is further defined as moving each of the pins along corresponding ramps to the bottom sections of the slots. 18. A method as set forth in claim 17 wherein the step of moving the actuator within the caming section to the engaged position is further defined as moving each of the pins along corresponding ramps to the top sections of the slots. 19. A method as set forth in claim 16 wherein the actuator includes a pair of rails with each one of said pins fixed to a corresponding one of said rails, and wherein the step of sliding the pins within corresponding slots is further defined as sliding the rails relative to the movable component in a direction transverse to the movement of the movable component. 20.
