Abstract
Abstract A liquid separator assembly for separating a liquid from a liquid-entrained vapor is provided. The separator assembly includes a housing having an interior wall that is configured to define a containment chamber. A downstream pipe is provided that is coupled to the housing and is in fluid communication with the containment chamber to discharge vapor from the housing. An upstream pipe is provided that is coupled to the housing and is in fluid communication with the containment chamber to introduce the liquid-entrained vapor into the housing. The upstream pipe is formed to include an expansion mechanism in the containment chamber for expanding and cooling the liquid-entrained vapor discharged in the containment chamber to induce condensation of the liquid entrained in the vapor onto the interior wall of the housing. A liquid return conduit is provided for conducting condensed liquid collecting in the containment chamber to a point of use.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
165 words
A liquid separator assembly comprising a housing means having an interior wall configured to define a containment expansion chamber means, surrounded by an environment to be at a relatively cool temperature, inlet means for admitting liquid-entrained vapor into the housing means from a relatively warmer vapor source than is said surrounding environment, outlet means for discharging air from the housing means to a first point of use, opening means located in the inlet means for directly passing the liquid entrained vapor from the inlet means into the containment expansion chamber means whereby said liquid entrained vapor is expanded through the opening means and condenses against said interior wall for separating liquid from the liquid-entrained air admitted into the housing means through the inlet means, and wherein said separated liquid collects in the housing means, and passageway means situated within the inlet means for conducting said separated liquid collected in said housing means to a second point of use through a portion of the inlet means.
Claim 2
Dependent Claim
165 words
A liquid separator assembly comprising a housing means having an interior wall configured to define a containment expansion chamber means, surrounded by an environment to be at a relatively cool temperature, inlet means for admitting liquid-entrained vapor into the housing means from a relatively warmer vapor source than is said surrounding environment, outlet means for discharging air from the housing means to a first point of use, opening means located in the inlet means for directly passing the liquid entrained vapor from the inlet means into the containment expansion chamber means whereby said liquid entrained vapor is expanded through the opening means and condenses against said interior wall for separating liquid from the liquid-entrained air admitted into the housing means through the inlet means, and wherein said separated liquid collects in the housing means, and passageway means situated within the inlet means for conducting said separated liquid collected in said housing means to a second point of use through a portion of the inlet means.
Claim 3
Dependent Claim
77 words
The assembly of claim 1, wherein the inlet means includes a first tube having an interior region interconnecting said vapor source and said containment expansion chamber means via said opening means and wherein said passageway means includes a second tube extending through the interior region of the first tube to conduct separated liquid from said housing means to the second point of use without intermixing said liquid-entrained vapor conducted through the first tube and said separated liquid.
Claim 4
Dependent Claim
41 words
The assembly of claim 1, wherein the inlet means includes a first tube having a distal portion situated in said housing and also formed with at least one exit aperture means for additionally exhausting liquid-entrained vapor into said containment expansion chamber.
Claim 5
Dependent Claim
74 words
The assembly of claim 3, wherein the containment expansion chamber has predetermined volume selected to cooperate with said at least one exit aperture means to also provided additional expansion for the vapor and for defining an air-cooling expansion region in the containment chamber just outside the at least one exit aperture means to induce condensation of liquid entrained in the vapor flowing through the exit aperture means on the interior wall of the housing.
Claim 6
Dependent Claim
83 words
The assembly of claim 3, wherein the first tube includes an annular side wall for channeling liquid-entrained vapor along a path into the housing, said annular side wall locating-said opening means which include at least one exit aperture means, and an end wall substantially blocking the flow of air through the first tube so that said vapor is diverted to flow at an angle to said path and exhausted through the at least one exit aperture means into said containment expansion chamber means.
Claim 7
Dependent Claim
55 words
The assembly of claim 3, wherein the outlet means includes a second air-conducting tube having a distal end portion situated in the housing and formed to include at least one inlet aperture means for admitting air from the containment expansion chamber into the second air-conducting tube for subsequent discharge to the first point of use.
Claim 8
Dependent Claim
66 words
The assembly of claim 6, wherein the distal portions of the first and second tubes are situated in spaced-apart relation, and the interior wall is configured to define a liquid collection basin in the containment expansion chamber underlying both said distal portions and communicating with the passageway means for conducting the separated liquid in the basin to the second point of use via the passageway means.
Claim 9
Dependent Claim
65 words
The assembly of claim 6, wherein the distal portion of the second air-conducting tube includes an annular side wall formed to include said at least one inlet aperture means and an end wall substantially blocking the flow of air into the second air-conducting tube and wherein the end wall includes funnel means for dispensing liquid accumulating in the second air-conducting tube into the containment chamber.
Claim 10
Dependent Claim
49 words
The assembly of claim 1, wherein the at least one aperture means for conducting air from the containment chamber into said second tube is of smaller cross-section size than the cross-section of the second tube wherein said at least one aperture means causes expansion of the air flowing therethrough.
