Abstract

A grease delivery system is provided which includes refilling containers with a fluid from a larger reservoir to eliminate excess cost and waste. The container and reservoir are connected using hoses, a pump, and quick connect couplings. The containers are used to provide equipment with the fluid.

First claim

What is claimed is:

1. A system for fluid delivery comprising:
a refillable reservoir configured for storing a fluid, the refillable reservoir including:
a refillable reservoir outlet; and,
a refillable reservoir outlet coupling;

a pump for moving the fluid;
a pump hose for conveying the fluid;
a pump hose coupling connected to the pump hose, the pump hose coupling including a pump hose quick connect and a valve; and,
at least one refillable container for receiving the fluid, the at least one refillable container including:
a refillable container inlet; and,
a pop-up indicator; and

a refillable container quick connect attached to the refillable container inlet, the refillable container quick connect being configured to be releasably coupled with the pump hose quick connect,
wherein the valve is separate from the pump hose quick connect, and
wherein each of the pump hose quick connect and the refillable container quick connect is a coupling that allows for attachment to another coupling without use of tools; the pump is able to move the fluid in the system from the refillable reservoir through the pump hose, the pump hose quick connect, and the refillable container quick connect to the refillable container.

2. The system of claim 1 , wherein the fluid is one of a grease, an oil, a liquid natural gas, a chemical, and combinations thereof.

3. The system of claim 1 , wherein the at least one refillable container is one of a drum and a keg.

4. The system of claim 1 , wherein one of the pump hose quick connect and the refillable container quick connect is a ¾ inch male hydraulic quick connect.

5. The system of claim 1 , wherein the pump is dedicated to the system.

6. The system of the claim 1 , wherein the pump is a quick transfer pump.

7. The system of claim 1 , wherein the refillable reservoir and the at least one refillable container are in fluid communication.

8. The system of claim 1 , wherein one of the pump hose quick connect and the refillable container quick connect is a ¾ inch female hydraulic quick connect.

9. The system of claim 1 , wherein the valve is one of a ball valve, a gate valve, a glove valve, a needle valve, a high pressure valve, a butterfly valve, a poppet valve, a ½ turn ball valve, and a ½ turn high pressure valve and the valve is separate from the pump hose quick connect.

10. The system of claim 1 , wherein the refillable container inlet is configured to receive the fluid therethrough from the refillable container quick connect.

11. The system of claim 1 , wherein the refillable reservoir outlet is configured to provide the fluid therethrough to the pump hose.

12. The system of claim 1 , further comprising a dust cover configured to cover the refillable container quick connect when the refillable container quick connect is not engaged with the pump hose quick connect.

13. The system of claim 1 , wherein at least one of the pump hose quick connect and the refillable container quick connect is one of an agricultural interchange, a diagnostic interchange, a high pressure screw together, a high pressure wing style, a flush face, and a wing style.

14. The system of claim 1 , wherein at least one of the pump hose quick connect and the refillable container quick connect is one male and female.

15. The system of claim 1 , wherein at least one of the pump hose quick connect and the refillable container quick connect is made of one of a steel, a brass, an aluminum, and a stainless steel.

16. The system of claim 1 , wherein at least one of the pump hose quick connect and the refillable container quick connect is one of a female NPT, a male NPT, a hose barb, and a push-on hose barb.

17. The system of claim 1 , wherein the pop-up indicator is attached to a lid of the at least one refillable container.

18. The system of claim 1 , wherein the refillable container inlet is proximate a bottom of the at least one refillable container.
