Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
An improved compressed air generating system comprising: a chargeable source of compressed air, air motor means driven from said chargeable source, means for regulating the flow of air from said source to said motor means for automatically maintaining substantially constant speed of said motor means during changes in pressure in said source, generator means driven by said air motor means, means for utilizing part of the electrical energy generated by said generator means for external power, an electromotor driven by a remaining part of said electrical energy, air compressor means driven by said electromotor, and means conducting the output of said air compressor means to said chargeable source.
Claim 2
Dependent Claim
108 words
An improved compressed air generating system comprising: a chargeable source of compressed air, air motor means driven from said chargeable source, means for regulating the flow of air from said source to said motor means for automatically maintaining substantially constant speed of said motor means during changes in pressure in said source, generator means driven by said air motor means, means for utilizing part of the electrical energy generated by said generator means for external power, an electromotor driven by a remaining part of said electrical energy, air compressor means driven by said electromotor, and means conducting the output of said air compressor means to said chargeable source.
Claim 3
Dependent Claim
54 words
A system in accordance with claim 1, further characterized in said air motor means being in the form of a turbine, and said regulating means being in the form of a rotary air sprayer in series with the flow of compressed air to said turbine, and sensitive to varying pressure in said chargeable source.
Claim 4
Dependent Claim
25 words
A system in accordance with claim 1, further characterized in said air compressor producing compressed air at a pressure above that in said chargeable source.
