Abstract
Abstract A separator device, and a method, for removing water and foreign matter entrained in a compressed fluid is disclosed. The device includes a housing having an inlet port fluidly connected to the compressed fluid source, an outlet port and a chamber fluidly connected to the inlet and outlet ports. A mechanism is provided for separating water entrained in the compressed fluid and for collecting the separated water. Finally, a mechanism periodically purges the collected separated water from the device. The water is, preferably, atomized as it is released from the device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
A device for separating solid particulate material and entrained liquid from an airstream comprising: a housing defining an interior chamber having a bottom portion, said housing having an inlet and an outlet open to said chamber, means contained within said housing chamber for separating solid particulate matter and entrained liquid from said airstream so that said separated solid particulate matter and said liquid collect in said bottom portion of said chamber, means for periodically purging liquid and solid particulate matter from the bottom portion of said chamber comprising a normally closed dump valve fluidly connected to said bottom portion of said chamber, means for moving said dump valve to an open position comprising an electrically operated valve having an inlet duct fluidly connected to said chamber and an outlet duct fluidly connected to said dump valve and timer means for periodically actuating said electrically operated valve.
Claim 2
Independent Claim
146 words
A device for separating solid particulate material and entrained liquid from an airstream comprising: a housing defining an interior chamber having a bottom portion, said housing having an inlet and an outlet open to said chamber, means contained within said housing chamber for separating solid particulate matter and entrained liquid from said airstream so that said separated solid particulate matter and said liquid collect in said bottom portion of said chamber, means for periodically purging liquid and solid particulate matter from the bottom portion of said chamber comprising a normally closed dump valve fluidly connected to said bottom portion of said chamber, means for moving said dump valve to an open position comprising an electrically operated valve having an inlet duct fluidly connected to said chamber and an outlet duct fluidly connected to said dump valve and timer means for periodically actuating said electrically operated valve.
Claim 3
Dependent Claim
16 words
The device as defined in claim 1 wherein said electrically operated valve comprises a solenoid valve.
Claim 4
Independent Claim
125 words
An apparatus for separating entrained contaminant matter from a conveying gaseous fluid, said apparatus comprising: a housing having a fluid inlet, a fluid outlet, and a portion defining a chamber fluidly connected to said fluid inlet and said fluid outlet; means, mounted in said chamber, for separating entrained contaminant matter from said conveying fluid as said conveying fluid is passed through said housing; means mounted in fluid communication with said chamber for periodically purging said separated entrained contaminant matter from said chamber at a predetermined time interval comprising a dump valve fluidly connected to said chamber, means for pneumatically actuating said dump valve; and wherein said pneumatic actuating means comprises means for periodically bleeding a portion of air from said outlet to said dump valve.
Claim 5
Independent Claim
125 words
An apparatus for separating entrained contaminant matter from a conveying gaseous fluid, said apparatus comprising: a housing having a fluid inlet, a fluid outlet, and a portion defining a chamber fluidly connected to said fluid inlet and said fluid outlet; means, mounted in said chamber, for separating entrained contaminant matter from said conveying fluid as said conveying fluid is passed through said housing; means mounted in fluid communication with said chamber for periodically purging said separated entrained contaminant matter from said chamber at a predetermined time interval comprising a dump valve fluidly connected to said chamber, means for pneumatically actuating said dump valve; and wherein said pneumatic actuating means comprises means for periodically bleeding a portion of air from said outlet to said dump valve.
Claim 6
Dependent Claim
52 words
The device as defined in claim 3 wherein said pneumatic actuating means further comprises: an electrically operated solenoid valve fluidly connected between said fluid outlet and said dump valve, and timer means connected to said electrically operated solenoid valve for periodically actuating said electrically operated solenoid valve at said predetermined time interval.
Claim 7
Dependent Claim
25 words
The device as defined in claim 4 and comprising means, fluidly connected to said dump valve, for atomizing a liquid contaminant purged from said chamber.
Claim 8
Independent Claim
71 words
A method for removing entrained contaminant matter including a liquid contaminant from a conveying gaseous fluid, said method comprising the steps of: separating the entrained contaminant matter in a chamber; and periodically purging the separated liquid contaminant matter from said chamber wherein said periodically purging step further includes removing the separated entrained contaminant liquid from said chamber and thereafter atomizing the separated entrained contaminant liquid into the atmosphere surrounding said chamber.
Claim 9
Independent Claim
71 words
A method for removing entrained contaminant matter including a liquid contaminant from a conveying gaseous fluid, said method comprising the steps of: separating the entrained contaminant matter in a chamber; and periodically purging the separated liquid contaminant matter from said chamber wherein said periodically purging step further includes removing the separated entrained contaminant liquid from said chamber and thereafter atomizing the separated entrained contaminant liquid into the atmosphere surrounding said chamber.
Claim 10
Independent Claim
193 words
An apparatus for separating entrained contaminant matter and liquid from a gaseous conveying fluid, said apparatus comprising: a housing having a fluid inlet, a fluid outlet, and a portion defining a chamber fluidly connected to said fluid inlet and said fluid outlet; means, mounted in said chamber, for separating entrained contaminant matter and liquid from said conveying fluid as said conveying fluid is passed through said housing; means for periodically purging said separated entrained contaminant matter and liquid from said chamber at a predetermined time interval; wherein said periodic purging means further comprises an electrically operated solenoid valve fluidly connected to said fluid outlet of said housing; said purging means comprising a dump valve fluidly connected to said chamber, said dump valve further being fluidly connected to said electrically operated solenoid valve; timer means, connected to said electrically operated solenoid valve, for periodically actuating said electrically operated solenoid valve at said predetermined time interval whereby said solenoid valve actuates said dump valve to eject separated entrained contaminant matter from said chamber; wherein said periodic purging means further comprises means, fluidly connected to said dump valve, for atomizing the liquid purged from said chamber.
