Filling valve apparatus having a quick connect/release mechanism
A filling valve apparatus having a flange for mounting to a beverage filling machine. A shank extends through the flange and is mounted to the beverage filling machine. A locking device is coupled to the shank with the locking device having an unlocked position loosely connected to the shank and a locked position with at least a portion of the locking device wedged between the flange and the shank for fixedly securing the filling valve apparatus to the beverage filling machine. The subject invention also includes a servicing kit for servicing the filling valve apparatus. The servicing kit includes the shank, the locking device, and a wrench assembly as well as other components.
1. A filling valve apparatus of a beverage filling machine for filling a container with a fluid, said apparatus comprising:
a body portion having a flange fixed relative to said body portion with at least one opening disposed within said flange and said body portion defining a cavity with at least one aperture for directing the fluid into the container;
a shank extending through said opening in said body portion and adapted to be mounted to the beverage filling machine;
said apparatus characterized by a locking device coupled to said shank with said locking device having an unlocked position loosely connected to said shank and a locked position with at least a portion of said locking device wedged between said flange and said shank for fixedly securing said filling valve apparatus to the beverage filling machine.
2. An apparatus as set forth in claim 1 wherein said locking device includes a caming surface for applying a clamping force against said flange when said locking device is in said locked position.
3. An apparatus as set forth in claim 2 further including a bushing disposed between said flange and said locking device with said caming surface engaging said bushing during said application of said clamping force.
4. An apparatus as set forth in claim 2 wherein said locking device includes a first lobe defining said caming surface for applying a progressive clamping force against said flange as said locking device moves from said unlocked position to said locked position.
5. An apparatus as set forth in claim 4 wherein said locking device includes a second lobe and a trough disposed between said first and second lobes to further define said caming surface.
6. An apparatus as set forth in claim 5 wherein said first lobe is substantially larger than said second lobe and said first lobe extends from a top of said locking device to a side of said locking device.
7. An apparatus as set forth in claim 5 further including a bushing disposed between said flange and said locking device with said first lobe engaging said bushing during said application of said clamping force and said second lobe engaging said bushing when said locking device is in said locked position to define a stop and to securely lock said locking device to said shank.
8. An apparatus as set forth in claim 7 wherein said bushing is formed of a polymeric material.
9. An apparatus as set forth in claim 1 wherein said shank has a distal end defining a ball.
10. An apparatus as set forth in claim 9 wherein said locking device includes an inner cavity and a first opening allowing access to said cavity with said ball disposed within said cavity when said locking device is coupled to said shank.
11. An apparatus as set forth in claim 10 wherein said shank further includes a neck disposed adjacent said ball and said first opening in said locking device includes a slot aligned with said neck when said locking device moves between said unlocked and locked positions.
12. An apparatus as set forth in claim 11 wherein said first opening in said locking device further includes an enlarged aperture in communication with said slot with said enlarged aperture complementary in size to said ball such that said ball can pass through said opening and into said cavity to align said shank with said slot.
13. An apparatus as set forth in claim 12 wherein said locking device includes a second opening allowing additional access to said cavity with said second opening being substantially transverse to said first opening.
14. An apparatus as set forth in claim 1 further including a stem mounted to said body portion within said cavity and defining a longitudinal passageway extending out of said body portion.
15. An apparatus as set forth in claim 14 further including a sleeve disposed over said stem and having a top and a bottom with said bottom extending into said cavity of said body portion.
16. An apparatus as set forth in claim 15 further including a seal mounted to said bottom of said sleeve for sealing said aperture of said body portion and preventing fluid from flowing through said aperture of said body portion.
17. An apparatus as set forth in claim 1 wherein said flange is integral to said body portion.
