Patent ID: 7720574

Claim:
A low volume, high pressure fluid dispensing system comprising: a pump for pumping a low volume of fluid at a high pressure; a pump adjustment device for adjusting the fluid flow from the pump; one or more fluid flow dispensing valves operated by the system fluid pressure to dispense less than 80 pints per day of lubricant at a pressure of greater than 500 psi, wherein the low volume of the fluid dispensing system is less than 80 pints per day of lubricant, and wherein the high pressure of the fluid dispensing system is greater than 500 psi; one or more fluid flow sensors, each associated with one of the one or more fluid flow dispensing valves, for measuring the fluid flow through the corresponding dispensing valve, the fluid flow sensor producing signals corresponding to fluid flow dispensing valve cycles; and a processor programmed to receive fluid flow information corresponding to fluid flow through the one or more fluid flow dispensing valves and to send a signal to the pump adjustment device to adjust the fluid flow from the pump if the fluid flow through the dispensing valve is not within a predetermined range, thereby allowing the fluid flow to be adjusted to prevent inadequate or excessive fluid flow.
