Abstract:
1. An automatic draining system for draining a first fluid from a filter, the automatic draining system comprising: a floating valve housed within a floating valve compartment having a floating valve opening, the floating valve having a density less than a first fluid and a density greater than a second fluid, wherein the floating valve is in a floating position when the floating valve compartment is filed with the first fluid allowing the first fluid to pass through the floating valve opening, and the floating valve is in a sealing position when the floating valve compartment is not filled with the first fluid, thereby preventing the first fluid and the second fluid from passing through the floating valve opening; a solenoid valve downstream of and in fluid communication with the floating valve compartment via the floating valve opening, the solenoid valve having a solenoid opening that is open when the solenoid valve is energized and is closed when the solenoid valve is de-energized; a first fluid collection cavity disposed downstream of and in fluid communication with the solenoid valve via the solenoid valve opening; wherein the first fluid collection cavity includes a drainage outlet for removing the first fluid contained within the first fluid cavity, the drainage outlet including an opening near a top end of the first fluid collection cavity configured to allow the first fluid to enter the drainage outlet when the first fluid approaches the top end of the first fluid collection cavity; and a filter media disposed in the first fluid collection cavity, wherein the filter media filters the first liquid prior to the first liquid exiting the automatic draining system.
