Abstract
Abstract Apparatus for securing capillary and other tubes within a refrigeration machine. A capillary retainer clip having a plurality of sections affixed thereto is mounted within a refrigeration machine such that the sections extending therefrom form elongated openings and spaced regions therebetween. The tubes are inserted between the sections such that the sections are displaced as the tube is slid through the opening to the spaced region. When the tube is in the spaced region the sections then return to their original position securing the tube within the spaced region.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
A refrigeration machine comprising a condenser, an evaporator, an expansion control device and a compressor for forming a closed refrigeration circuit, the expansion control device including a capillary tube mounted to conduct refrigerant from the condenser to the evaporator and means for supporting the capillary tube intermediate the ends thereof, said means including a retainer having a plurality of spaced resilient sections, the sections being formed to define elongated openings therebetween, the confronting sides of which form a spaced region adapted to forcibly engage the exterior surface of the capillary tube as it is passed through said elongated opening.
Claim 2
Dependent Claim
99 words
A refrigeration machine comprising a condenser, an evaporator, an expansion control device and a compressor for forming a closed refrigeration circuit, the expansion control device including a capillary tube mounted to conduct refrigerant from the condenser to the evaporator and means for supporting the capillary tube intermediate the ends thereof, said means including a retainer having a plurality of spaced resilient sections, the sections being formed to define elongated openings therebetween, the confronting sides of which form a spaced region adapted to forcibly engage the exterior surface of the capillary tube as it is passed through said elongated opening.
Claim 3
Dependent Claim
38 words
The invention as set forth in claim 1 wherein the means for supporting the capillary tube further includes a base having means to be attached within the refrigeration machine for securing the means for supporting the capillary tube.
Claim 4
Dependent Claim
45 words
The invention as set forth in claim 1 wherein the elongated openings between the sections have a plurality of spaced regions of varying sizes formed by the confronting sides of the elongated openings such that different size capillary tubes may be engaged within the regions.
Claim 5
Dependent Claim
54 words
The invention as set forth in claim 3 wherein the elongated openings are wider at the end which first receives the capillary tube and taper inwardly such that they are narrower at the opposite end, the spaced regions being circular in configuration and also decreasing in diameter along the length of the elongated opening.
Claim 6
Dependent Claim
90 words
A refrigeration machine comprising a condenser, an evaporator, an expansion control device and a compressor for forming a closed refrigeration circuit, a capillary tube for monitoring the refrigeration machine operation and means for supporting the capillary tube intermediate the ends thereof, said means including a retainer having a plurality of spaced resilient sections, the sections being formed to define elongated openings therebetween, the confronting sides of which form a spaced region adapted to forcibly engage the exterior surface of the capillary tube as it is passed through said elongated opening.
Claim 7
Dependent Claim
90 words
A refrigeration machine comprising a condenser, an evaporator, an expansion control device and a compressor for forming a closed refrigeration circuit, a capillary tube for monitoring the refrigeration machine operation and means for supporting the capillary tube intermediate the ends thereof, said means including a retainer having a plurality of spaced resilient sections, the sections being formed to define elongated openings therebetween, the confronting sides of which form a spaced region adapted to forcibly engage the exterior surface of the capillary tube as it is passed through said elongated opening.
Claim 8
Dependent Claim
64 words
The invention as set forth in claim 5 wherein the elongated opening between the sections have a plurality of spaced regions being circular in configuration and of varying sizes formed by the confronting sides of the elongated openings such that different size capillary tubes may be engaged within the regions and wherein said elongated openings taper from a wider end to a narrower end.
