Abstract
Description
- The present invention relates to grease couplers.
- Grease couplers connect a grease nipple to pressurised grease from a grease gun.
- Conventional couplers suffer from several drawbacks. It is difficult to positively couple and uncouple the coupler and the nipple, particularly under high grease pressure. This requires noticeable physical effort and also leads to wear and tear, or even failure of the components. The lack of positive coupling and uncoupling also leads to leaking of grease, or even spurting of high pressure grease back onto an operator. Furthermore, build-up of back pressure inside the coupler can lead to the formation of hydraulic lock which prevents positive uncoupling of the coupler and the nipple. Most conventional quick-release couplers are bulky which poses problems of access to tight greasing points.
- In this context, there is a need for improved grease couplers.
- According to the present invention, there is provided a grease coupler, comprising:
- an outer sleeve axially movable on an inner sleeve, each of which has an inlet end and an outlet end;
- a connection body connected to the inlet end of the inner sleeve;
- a collar axially movable on the outer sleeve between the connection body and the inlet end of the outer sleeve;
- a collar spring on the inlet end of the inner sleeve between the collar and the connection body to axially bias the collar toward the outlet end of the outer sleeve;
- jaws axially and radially movable in the outlet end of the outer sleeve to lock and unlock with a grease nipple;
- a nozzle axially movable in the outlet end of the outer sleeve between the jaws and the outlet end of the inner sleeve;
- a nozzle spring in the inner sleeve between the nozzle and the connection body;
- a collar ball groove in the collar and a corresponding inner ball groove in the inner sleeve;
- sleeve locking balls axially and radially movable between the collar ball groove and the inner ball groove via ball holes in the outer sleeve;
- a nozzle ball groove in the nozzle; and nozzle locking balls in the outlet end of the inner sleeve and axially movable within a limited axial distance defined by the nozzle ball groove;
- wherein a first retraction of the collar axially away from the outlet end of the outer sleeve pre-arms the grease coupler for coupling to the grease nipple by axially and radially moving the sleeve locking balls from the collar ball groove to the inner ball groove to lock the outer sleeve and the inner sleeve to one another to thereby permit relative axial movement between the outer sleeve and the nozzle to lock the jaws;
- wherein pushing the grease nipple inside the outlet end of the outer sleeve initially moves the nozzle axially away from the jaws to unlock the jaws and compress the nozzle spring, and subsequently moves the nozzle axially toward the grease nipple under spring pressure by the nozzle spring to thereby relock the jaws and positively couple the nozzle to the grease nipple; and
- wherein a second retraction of the collar axially away from the outlet end of the outer sleeve moves the sleeve locking balls from the inner ball groove to the collar ball groove to unlock the outer sleeve and the inner sleeve from one another to thereby permit relative axial movement between the outer sleeve and the nozzle to thereby unlock the jaws from the grease nipple, while relative axial movement between the nozzle and the inner sleeve is limited by axial movement of the nozzle locking balls within the limited axial distance defined by the nozzle ball groove to thereby positively uncouple the nozzle from the grease nipple.
- The outlet end of the outer sleeve may have an inwardly inclined lip, wherein the jaws are axially and radially movable against the inwardly inclined lip to lock and unlock with the grease nipple.
- A nozzle flange may extend radially from the nozzle to axially move the jaws toward the inwardly inclined lip at the outlet end of the outer sleeve.
- A pair of finger grips may extend radially from the collar to axially move the collar axially away from the outlet end of the outer sleeve.
- A ball check valve may be provided in the connection body.
- The ball check valve may be an adjustable ball check valve.
- The present invention also provides a method, comprising positively coupling and uncoupling a grease nipple to pressurised grease from a grease gun using the grease coupler described above.
- Embodiments of the invention will now be described by way of example only with reference to the accompanying drawings, in which:
-
FIGS. 1 and 2 are perspective front and rear views of a grease coupler according to an embodiment of the present invention; -
FIG. 3 is a section view of the grease coupler in an uncoupled state; -
FIGS. 4 to 6 are sequential section views showing pre-arming of the grease coupler for coupling with a grease nipple; -
FIGS. 7 to 9 are sequential section views showing positive coupling of the grease coupler to the grease nipple; and -
FIGS. 10 to 13 are sequential section views showing positive uncoupling of the grease coupler from the grease nipple. - Referring to
FIGS. 1 and 2 , agrease coupler 10 according to an embodiment of the present invention may generally comprise anouter sleeve 12, anactuation collar 14, and aconnection body 16. A pair offinger grips 18 may extend radially from thecollar 14 to axially move thecollar 14 axially away from an outlet end of theouter sleeve 12. Theconnection body 16 may be threadingly connectable to a grease gun hose (not shown). Clampingjaws 20 may be provided in an outlet end of theouter sleeve 12 to lock and unlock with a grease nipple, for example, a Zerk nipple (not shown). Thefinger grips 18 may be a moulding of suitable plastics materials, while the remaining components may be formed from suitable metals or metal alloys unless stated otherwise. - Referring to
FIG. 3 , theouter sleeve 12 may be axially movable on aninner sleeve 22. Theouter sleeve 12 and theinner sleeve 22 may each have an inlet end and an outlet end. Theconnection body 16 may be threadingly connected to the inlet end of theinner sleeve 22. Thecollar 14 may be axially movable on theouter sleeve 12 between theconnection body 16 and the inlet end of theouter sleeve 12. Acollar spring 24 may be provided on the inlet end of theinner sleeve 22 between thecollar 14 and theconnection body 16 to axially bias thecollar 14 toward the outlet end of theouter sleeve 22. - The
jaws 20 may be axially and radially movable in the outlet end of theouter sleeve 12 to lock and unlock with agrease nipple 26. The outlet end of theouter sleeve 12 may have an inwardlyinclined lip 28, and thejaws 20 may be axially and radially movable against the inwardlyinclined lip 28 to lock and unlock with thegrease nipple 26. Thejaws 20 may comprise threejaws 20 spaced circumferentially around 120° from one another each other in a floating configuration for gripping thegrease nipple 26. This configuration advantageously provides maximum grip surface, and lower and more even contact stress ongrease nipples 26 to avoid damaging them. In comparison to four jaws spaced circumferentially around 90° from one another, the three-floating configuration of thejaws 20 is more versatile and conforms better to standardised shapes, sizes and tolerances of grease nipples 26 (eg, SAE J534, BS1486 and DIN71412 applicable standards). This is advantageous asgrease nipples 26 are no longer machined for cost reasons, and hence are not as dimensionally accurate and consistent as they used to be. - A
nozzle 30 may be axially movable in the outlet end of theouter sleeve 12 between thejaws 20 and the outlet end of theinner sleeve 22. Theconnection body 16, theinner sleeve 22, theouter sleeve 12, thenozzle 30 may collectively define a flow passage for pressurised grease from the grease gun hose to thegrease nipple 26. Anozzle spring 32 may be provided in theinner sleeve 22 between thenozzle 30 and theconnection body 16. Arubber nozzle seal 34 may be provided in thenozzle 30. Anozzle flange 36 may extend radially from thenozzle 30 to axially move thejaws 20 toward the inwardlyinclined lip 28 at the outlet end of theouter sleeve 12. - A
collar ball groove 38 may be formed in thecollar 14, and a correspondinginner ball groove 40 may be formed in theinner sleeve 22.Sleeve locking balls 42 may be axially and radially movable between thecollar ball groove 38 and theinner ball groove 40 viaball holes 44 formed in theouter sleeve 12. - A
nozzle ball groove 46 defining a limited axial distance may be formed in thenozzle 30.Nozzle locking balls 48 may be provided in the outlet end of theinner sleeve 22 to be axially movable within the limited axial distance defined by thenozzle ball groove 46. Thenozzle locking balls 48 may be axially retained by a retainingring 50 and a snap ring (or circlip) 52. An O-ring 54 may be provided in an O-ring groove on theinner sleeve 22 axially inward of the nozzle. - A ball check valve 56 may be provided in the
connection body 16. The ball check valves 56 may comprise avalve spring 58, avalve ball 60 and an adjustablevalve seat ring 62 that provides selectively adjustable limitation of pressurised grease flow from the grease gun hose after disconnection. - Referring to
FIG. 4 , a first retraction of thecollar 14 axially away from the outlet end of theouter sleeve 12 pre-arms thegrease coupler 10 for coupling to thegrease nipple 26 by axially and radially moving thesleeve locking balls 42 from thecollar ball groove 38 to theinner ball groove 40 to lock theouter sleeve 12 and theinner sleeve 22 to one another to thereby permit relative axial movement between theouter sleeve 12 and thenozzle 30 to lock thejaws 20. As illustrated inFIG. 5 , after the first retraction, thecollar 14 is axially biased back toward the outlet end of theouter sleeve 12 by thecollar spring 24. This leaves thegrease collar 10 pre-armed and ready to positively couple to thegrease nipple 26, as illustrated inFIG. 6 . - Referring to
FIG. 7 , pushing thegrease nipple 26 inside the outlet end of theouter sleeve 12 initially moves thenozzle 30 axially away from thejaws 20 to unlock thejaws 20 and compress thenozzle spring 32. As illustrated inFIG. 8 , thenozzle 30 is subsequently moved axially toward thegrease nipple 26 under spring pressure by thenozzle spring 32 to thereby relock thejaws 20 and positively couple thenozzle 30 to thegrease nipple 26. This leaves thegrease coupler 10 in a positively coupled state with the grease nipple, as illustrated inFIG. 9 , to allow pressurised grease to be supplied from the grease gun hose to thegrease nipple 26. - Referring to
FIGS. 10 to 13 , a second retraction of thecollar 14 axially away from the outlet end of theouter sleeve 12 moves thesleeve locking balls 42 from theinner ball groove 40 back into thecollar ball groove 38 to unlock theouter sleeve 12 and theinner sleeve 22 from one another to thereby permit relative axial movement between theouter sleeve 12 and thenozzle 30 to unlock thejaws 20 from thegrease nipple 26, while relative axial movement between thenozzle 30 and theinner sleeve 22 is limited by thenozzle locking balls 48 axially moving within the limited axial distance defined by thenozzle ball groove 46 to positively uncouple thenozzle 30 from thegrease nipple 26. The positive nozzle retention provided by thenozzle ball groove 46 and thenozzle locking balls 48 during uncoupling may overcome any hydraulic lock between thegrease nipple 26 and thenozzle 30 from build-up of back pressure inside thegrease coupler 10. - Embodiments of the present invention provide grease couplers that are useful for positively coupling and uncoupling grease nipples to pressurised grease from grease guns, while avoiding or minimising leaking or back spurting of grease.
