A method for assembling an accumulator dehydrator comprising a cap, a fitting and a deflector, the deflector having a body and an arcuate flange extending from it, the method comprising providing a cap having an opening through it, the fitting having a portion smaller than the opening, the steps including placing the fitting on the outside of the cap and inserting the portion of it into the opening, placing the deflector on the inside of the cap and inserting the flange of it into the opening, exteriorly of the fitting, and welding the fitting to the cap.

Method of assembling an accumulator dehydrator

An accumulator dehydrator is disclosed having a deflector for directing the flow of refrigerant into the dehydrator, said deflector formed of sheet metal, and permanently secured in operative position by component parts of the accumulator dehydrator. The deflector is provided with a planar body portion which is disposed at an angle to the flow of the incoming refrigerant, and is provided with flanges which inhibit lateral flow of the refrigerant. The deflector is also provided with a portion of arcuate configuration, which is clamped to the accumulator dehydrator in a manner which prevents movement in any direction relatively to the accumulator dehydrator.

A hose cutoff device or tool is disclosed which is especially adapted for cutting lengths of hose for use in hose assemblies for automotive air-conditioning systems. The device or tool comprises a base which is provided with axially-spaced, axially aligned, tubes for the reception of the hose to be cut, and with a manually-operable handle which is pivotally secured to the base, and is provided with a cutter blade which is movable through the hose to sever the hose into desired lengths. The cutter blade is of unique design or construction, is removably secured to the handle, and can be quickly and easily replaced when worn. A guard is provided for limiting movement of the handle away from the base and for partially enclosing the cutter blade.

Hose cutoff device or tool

A device or tool is disclosed for assembling the hose and fitting of hose assemblies used in automotive air conditioning systems. The device comprises means for supporting the hose and fitting in spaced axial alignment with each other, and means including a handle and linkage responsive to movement of the handle for causing toothed rolls to engage diametrically opposite sides of the hose and force the hose over the end portion of the fitting. The toothed rolls are mounted eccentrically of studs on the handle and linkage, so as to vary the spacing between the rolls to accommodate therebetween hoses of different diameter.

Torque transmitting fluid couplings of two types are described, one a thermatically controlled coupling and the other a torque limiting coupling. Both are characterized by the use of parts which can be manufactured at low cost and easily and quickly assembled, and contribute to greater efficiency in operation than fluid couplings of these types which have heretofore been marketed. Both utilize a housing or casing which is die-cast complete and finish bored, a drive shaft and coupling flange made of two separate pieces, which are welded together, ball bearing mounts, a cover or cover member made as a metal stamping, and a drive disc which is die-cast, in a single piece, to provide a friction ring and friction segments molded integrally therewith. In the thermatically-controlled type, the cover is part of a cover assembly, which comprises a bracket for supporting a bimetal strip, a steel guide bushing riveted to the cover and in which a piston or pin is adapted to be slidably mounted, and a rubber piston seal for preventing leakage of fluid through the cover. The thermatically-controlled type also includes a plate and spring assembly, comprising a divider plate made as a steel stamping and a spring made of spring steel and supporting a weir made of a graphite-filled material.

Torque transmitting fluid couplings

A compressor block and tube assembly is disclosed having spaced openings for the reception of the ends of tubes for admitting fluid to and from a compressor. Means are provided for interlocking the tubes to the block, whereby relative axial movement of the tubes in said openings is avoided. The tubes are provided with conical shoulders and beads for this purpose, and O-rings are interposed between the beads and the block to provide leak-proof seals between the tubes and block. The block is of such design as to facilitate production in mass quantities.

Compressor block and tube assembly

The invention is concerned with the provision of a hose assembly in which the hose is clamped between a tube or nipple and a shell, and the shell is provided with a body portion which is crimped to the hose. The shell is entirely independent of and unattached to the tube or nipple, thereby facilitating removal of the shell from the assembly in a situation where the hose has burst or become damaged, and a new hose must be used to replace it in the assembly. The shell is provided with an inturned flange which functions as a stop for the end of the hose, and the tube or nipple is provided with an annular bead, one side of which functions as a stop to predetermine the position of the tube or nipple relatively to the end of the hose.

Hose assembly

A suction throttling valve is provided which is especially adapted for use as a part of a compact unit consisting of a thermostatic expansion valve, suction throttling valve, and a receiver-dryer, in an automotive air conditioning system. The suction throttling valve is characterized by the incorporation therein of a bellows assembly of unique construction, which includes a bellows, an evacuating tube for evacuating the bellows to a predetermined pressure, and a needle valve. The bellows assembly can be easily and quickly adjusted relatively to the valve housing, in a manner such as to obviate the use of extremely expensive and sophisticated testing equipment. Construction has also been simplified to eliminate certain parts previously used in other valves of this character.
