Patent ID: 8636175

Claim:
A system for dispensing fluid, the system comprising; a first fluid circuit, the first fluid circuit comprising, a first reservoir configured to contain a supply of a first fluid for being dispended, a first variable volume chamber in flow communication with the first fluid circuit, the first variable volume chamber being configured to increase and decrease in volume; and a second fluid circuit configured to provide pressure for dispensing the first fluid, the second fluid circuit comprising, a second reservoir configured to contain a supply of a second fluid, fluid passages configured to provide fluid flow within the second fluid circuit, a pump configured to pump the second fluid within the fluid passages, and a second variable volume chamber in flow communication with the second fluid circuit, the second variable volume chamber being configured to increase and decrease in volume, wherein the second fluid circuit is a closed-loop circuit, wherein the first variable volume chamber and the second variable volume chamber are associated with one another, such that as the volume of the second variable volume chamber increases, the volume of the first variable volume chamber decreases, thereby dispensing the first fluid from the first fluid circuit, and wherein the fluid passages of the second fluid circuit are associated with the first fluid circuit, such that flow of the second fluid in the second fluid circuit facilitates control of a temperature of the first fluid in the first fluid circuit.
