Abstract
Abstract An electric motor including a stator and rotor are electrically connected for operation. The stator includes a first portion having a bore provided therein. A member defining a cylinder is disposed in the bore. A shaft is operably connected to the rotor to rotate therewith. A piston, disposed in the cylinder, is operably connected to the shaft, rotation of the shaft causing the piston to reciprocate within the cylinder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A motor-compressor unit comprising: a. rotor means; b. a stator electrically coupled to said rotor means and having means defining a bore provided in a first portion thereof, energization of said stator causing said rotor means to rotate; c. means defining a cylinder disposed in said bore of said stator; d. shaft means operatively connected to said rotor means for rotation therewith, said shaft means extending transversely to said bore; and e. piston means disposed in said cylinder means and connected to said shaft means, rotation of said shaft means causing said piston means to reciprocate in said cylinder means.
Claim 2
Dependent Claim
100 words
A motor-compressor unit comprising: a. rotor means; b. a stator electrically coupled to said rotor means and having means defining a bore provided in a first portion thereof, energization of said stator causing said rotor means to rotate; c. means defining a cylinder disposed in said bore of said stator; d. shaft means operatively connected to said rotor means for rotation therewith, said shaft means extending transversely to said bore; and e. piston means disposed in said cylinder means and connected to said shaft means, rotation of said shaft means causing said piston means to reciprocate in said cylinder means.
Claim 3
Dependent Claim
70 words
An electric motor provided to motivate a pump having a shaft comprising: a. rotor means coupled to said shaft; and b. a stator electrically coupled to said rotor means and having means defining first and second bores, the shaft of said pump being rotatably positioned in said second bore, said first bore extending transversely to said second bore, energization of said stator causing said rotor means and shaft to rotate.
Claim 4
Dependent Claim
70 words
An electric motor provided to motivate a pump having a shaft comprising: a. rotor means coupled to said shaft; and b. a stator electrically coupled to said rotor means and having means defining first and second bores, the shaft of said pump being rotatably positioned in said second bore, said first bore extending transversely to said second bore, energization of said stator causing said rotor means and shaft to rotate.
Claim 5
Dependent Claim
168 words
A hermetically sealed electric reciprocating motor-compressor unit comprising: a. rotor means; b. a stator electrically coupled to said rotor means and having means defining a bore provided in a first portion thereof, energization of said stator causing said rotor means to rotate, said stator further including longitudinally extending passage means; c. means defining a cylinder disposed in said bore means; d. means to supply a gas to be compressed to said passage means, said gas passing through said passage means in heat transfer relation with said rotor means and stator, said gas thence being supplied to said cylinder means; e. shaft means operatively connected to said rotor means for rotation therewith, and extending transversely to said bore means; f. piston means disposed in said cylinder means and connected to said shaft means, rotation of said shaft means causing said piston means to reciprocate in said cylinder means to compress said gas provided therein; and g. discharge means connected to said cylinder means to receive said compressed gas therefrom.
Claim 6
Dependent Claim
168 words
A hermetically sealed electric reciprocating motor-compressor unit comprising: a. rotor means; b. a stator electrically coupled to said rotor means and having means defining a bore provided in a first portion thereof, energization of said stator causing said rotor means to rotate, said stator further including longitudinally extending passage means; c. means defining a cylinder disposed in said bore means; d. means to supply a gas to be compressed to said passage means, said gas passing through said passage means in heat transfer relation with said rotor means and stator, said gas thence being supplied to said cylinder means; e. shaft means operatively connected to said rotor means for rotation therewith, and extending transversely to said bore means; f. piston means disposed in said cylinder means and connected to said shaft means, rotation of said shaft means causing said piston means to reciprocate in said cylinder means to compress said gas provided therein; and g. discharge means connected to said cylinder means to receive said compressed gas therefrom.
Claim 7
Dependent Claim
45 words
