Fluid supply apparatus

An apparatus comprising:

• a fitting attachable to a device that requires lubrication or the supply of fluid, wherein the fitting includes an insertable section and a fitting channel connecting with one or more entry ports opening on to at least one circumferential groove in an external side of the insertable section of the fitting, and a second exit through an end of the fitting distal to the insertable section, and wherein the fitting further includes at least one sealing groove on either side of the circumferential groove and provided with a continuous flexible seal;
• a complementary coupler connectable to a fluid reservoir, wherein the coupler comprises a body and a hole including an inside wall, the hole being dimensioned to be a close fit over the insertable section of the fitting, wherein the coupler further includes one or more feed channels, wherein each feed channel having one or more feed channel exits through the inside wall of the hole;
• and
• such that when the insertable section is in a delivery position in the hole, a fluid can be transferred under pressure from the fluid reservoir via the feed channel to the fitting channel, wherein the fluid is able to leave the feed channel through at least one feed channel exit and pass into the fitting channel via at least one of the entry port.

• a complementary coupler connectable to a fluid reservoir wherein the coupler comprises a body and a hole including an inside wall, the hole being dimensioned to be a close fit over the insertable section of the fitting and includes at least one vent hole adapted to allow unwanted fluid to escape there from, wherein the coupler further includes one or more feed channels, wherein each feed channel having one or more feed channel exits through the inside wall of the hole and the hole of the coupler defines an axis of insertion, and the feed channel exits are at an angle with respect to the axis of insertion;
• and
• such that when the insertable section is in a delivery position in the hole, a fluid can be transferred under pressure from the fluid reservoir via the feed channel, to the fitting channel, wherein the fluid is able to leave the feed channel through at least one feed channel exit, and pass into the fitting channel via at least one the entry port.

An apparatus for supply of gases comprising:

• a fitting assembly for providing gases from a gases supply, to a component to be pressurized or inflated, wherein the fitting comprises of an elongate valve body having a first end, and a second end, and being at least partially hollow to define a valve body wall, a valve core slidably located within the hollow valve body, wherein the valve body includes at least one passageway within the valve body wall, and wherein the passageway begins at an entry port on an internal face of the hollow of the valve body, and at least an initial portion of the passageway extends transverse to the valve body, and terminates at an exit located a distance from the first end of the valve body, wherein the valve core, when in a first position blocks the entry port, and when in a second position opens the entry port;
• and
• a coupler to couple with a fitting comprising an elongate body having a first inlet end, and a second outlet end, wherein the inlet end is adapted to receive gas from the gaseous supply, and the outlet end is adapted to couple with a fitting, a receiving recess in the outlet end of the body defining an inner projection, and surrounding the inner projection, a gas supply passageway extending from the inlet through the projection, and terminating in at least one exit port in an outer wall of the projection, wherein the exit port is adapted to expel gas in a direction transverse to an axis of the body.
