Abstract
Abstract Apparatus for cooling liquids, especially lubricating oil for internal combustion engines or heat engines, etc., including a heat exchanger formed by at least one tube for circulating said liquid to be cooled, immersed in a cooling liquid. The exchanger is connected to the outside circuit by connectors passing through the wall of the container of the cooling liquid. These connectors are formed in two parts, one of which projects externally, said parts being so shaped that when assembled they jointly form an annular cavity which surrounds the edge of the opening formed in the container wall; the volume of said cavity diminishes gradually when said two parts are joined together whereby to confine and tighten a flexible seal placed within said cavity.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
Apparatus for cooling liquid, such as oil, including an exchanger disposed within a container having a wall and being filled with a cooling medium, such as water, said wall having passages therethrough, fluid connectors fixed to said exchanger for the inflow and outflow of the liquid to be cooled and extending through the passages in said container wall, each connector comprising two parts, each part extending through said container wall from opposite sides thereof, one part penetrating the other part, said two parts, when assembled together, forming an annular cavity closed on at least one side of said container wall and enclosing the rim of the passage associated therewith and an annular seal arranged in said cavity astride the rim of said passage and substantially filling said cavity, the volume of said cavity gradually diminishing and compressing said seal during assembly of said two parts.
Claim 2
Dependent Claim
145 words
Apparatus for cooling liquid, such as oil, including an exchanger disposed within a container having a wall and being filled with a cooling medium, such as water, said wall having passages therethrough, fluid connectors fixed to said exchanger for the inflow and outflow of the liquid to be cooled and extending through the passages in said container wall, each connector comprising two parts, each part extending through said container wall from opposite sides thereof, one part penetrating the other part, said two parts, when assembled together, forming an annular cavity closed on at least one side of said container wall and enclosing the rim of the passage associated therewith and an annular seal arranged in said cavity astride the rim of said passage and substantially filling said cavity, the volume of said cavity gradually diminishing and compressing said seal during assembly of said two parts.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1, wherein said annular seal is made of tetrafluoroethylene.
Claim 4
Dependent Claim
124 words
Apparatus for cooling liquid, such as oil, including an exchanger disposed within a container having a wall and being filled with a cooling medium, such as water, said wall having passages therethrough, fluid connectors fixed to said exchanger for the inflow and outflow of the liquid to be cooled, each connector comprising a first part and a second part adapted to be assembled together, said first connector part having an end extending through an associated passage in said wall, said connector end having a thinned-down lip, said second connector part extending through said associated passage including a section having a frusto-conical surface confronting said lip, said frusto-conical surface bearing against said lip and imparting a deformation thereto when said connector parts are assembled together.
Claim 5
Dependent Claim
124 words
Apparatus for cooling liquid, such as oil, including an exchanger disposed within a container having a wall and being filled with a cooling medium, such as water, said wall having passages therethrough, fluid connectors fixed to said exchanger for the inflow and outflow of the liquid to be cooled, each connector comprising a first part and a second part adapted to be assembled together, said first connector part having an end extending through an associated passage in said wall, said connector end having a thinned-down lip, said second connector part extending through said associated passage including a section having a frusto-conical surface confronting said lip, said frusto-conical surface bearing against said lip and imparting a deformation thereto when said connector parts are assembled together.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 3, wherein at least one of the connector parts includes a flange with a cross-section larger than its associated passage in the container wall.
Claim 7
Dependent Claim
128 words
Apparatus for cooling liquid, such as oil, including an exchanger disposed within a container having a wall and being filled with a cooling medium, such as water, said wall having passages therethrough, fluid connectors fixed to said exchanger for the inflow and outflow of the liquid to be cooled and extending through the passages in said container wall, each connector comprising two parts, said two parts, when assembled together, forming an annular cavity closed on at least one side of said container wall and enclosing the rim of the passage associated therewith and an annular seal arranged in said cavity astride the rim of said passage and substantially filling said cavity, said seal comprising at least two rings, at least one of said rings having a semi-circular cross-section.
Claim 8
Dependent Claim
128 words
Apparatus for cooling liquid, such as oil, including an exchanger disposed within a container having a wall and being filled with a cooling medium, such as water, said wall having passages therethrough, fluid connectors fixed to said exchanger for the inflow and outflow of the liquid to be cooled and extending through the passages in said container wall, each connector comprising two parts, said two parts, when assembled together, forming an annular cavity closed on at least one side of said container wall and enclosing the rim of the passage associated therewith and an annular seal arranged in said cavity astride the rim of said passage and substantially filling said cavity, said seal comprising at least two rings, at least one of said rings having a semi-circular cross-section.
Claim 9
Dependent Claim
54 words
Apparatus according to claim 5, wherein at least one of said two parts includes a flange having a cross-section larger than the passage in the container wall, said flange having a peripheral projection extending toward the container wall, said projection being closely spaced from said container wall when said two parts are assembled together.
Claim 10
Dependent Claim
203 words
Apparatus for cooling liquid including a heat exchanger disposed within a container having a wall formed of a synthetic plastic material and adapted to be filled with a cooling medium, said wall having passages therethrough, fluid connectors formed of a metallic material and fixed to said exchanger for the inflow and outflow of the liquid to be cooled and extending through the passages in said container wall, each connector comprising two parts adapted to be assembled together and extending through said container wall from opposite sides thereof, said two parts, when assembled together, forming an annular cavity closed on at least one side of said container wall and enclosing the rim of the passage associated therewith and an annular seal arranged in said cavity astride the rim of said passage and substantially filling said cavity, one of said connector parts including an end having a thinned-down lip, the other connector part including a section having a frusto-conical surface confronting said lip, said frusto-conical surface bearing against said lip and deforming said lip outwardly toward said annular cavity when said connector parts are assembled together to thereby compress the seal in said cavity and form a sealed connection between said connector and container wall.
