Abstract
Abstract A compressor having a mounting plate perpendicular to the walls of the compressor can is assembled by mounting the compressor pump to the mounting plate, and then welding the mounting plate in place within the can into which the stator of the motor assembly has already been placed. The rotor may be placed on the pump shaft prior to placement of the pump-mounting plate assembly within the can, or may be placed on the shaft after the mounting plate has been welded within the can.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A method for assembling a compressor wherein the compressor pump is attached to a mounting plate comprising: a. attaching a compressor pump to a mounting plate, said mounting plate being adapted for attachment within a compressor can; b. fitting a stator within the compressor can; c. providing means on said can aligned with said stator, for attachment of said mounting plate; d. inserting said mounting plate with said compressor pump attached into said compressor can such that the shaft of said compressor pump is within the opening of said stator; e. aligning said shaft within said stator with an aligning mandrel; and f. firmly attaching said mounting plate to said can.
Claim 2
Independent Claim
111 words
A method for assembling a compressor wherein the compressor pump is attached to a mounting plate comprising: a. attaching a compressor pump to a mounting plate, said mounting plate being adapted for attachment within a compressor can; b. fitting a stator within the compressor can; c. providing means on said can aligned with said stator, for attachment of said mounting plate; d. inserting said mounting plate with said compressor pump attached into said compressor can such that the shaft of said compressor pump is within the opening of said stator; e. aligning said shaft within said stator with an aligning mandrel; and f. firmly attaching said mounting plate to said can.
Claim 3
Dependent Claim
30 words
The assembly of claim 1 wherein the rotor of said motor assembly is attached to said shaft, within said stator opening, following attachment of said mounting plate to said can.
Claim 4
Dependent Claim
19 words
The assembly method of claim 2 wherein end caps are attached to said can following attachment of the rotor.
Claim 5
Dependent Claim
42 words
The assembly method of claim 1 wherein the compressor pump is loosely attached to said mounting plate prior to insertion of said mounting plate-pump assembly into said can and said attachment is made firm after alignment of said shaft and said stator.
Claim 6
Dependent Claim
24 words
The assembly method of claim 1 wherein said compressor pump is held in place radially prior to alignment of said shaft within said stator.
Claim 7
Dependent Claim
43 words
The assembly method of claim 1 wherein the rotor of said motor assembly is attached to said shaft prior to insertion of said mounting plate-compressor pump assembly into said can and said rotor is aligned within said stator opening, thus aligning the shaft.
