Abstract
Abstract A composite inlet, filter and noise suppressor enclosure to be connected to apparatus for compressing air or gas includes at least one compartment lined with sound absorbing material having an inlet passage for the air or gas to be compressed with which a single or multi-stage filter coacts, an outlet passage which communicates with the suction inlet of the compressor in the compressing apparatus, and a by-pass conduit for delivering compressed air or gas from the compressing apparatus for recycling the same through the chamber and the outlet passage back to the compressor. The chamber in addition to said sound absorbing material having means therein for both suppressing or silencing the air or gas flowing from the inlet through the chamber to the compressor or from the by-pass and blow-off system through the chamber to the compressor. The enclosure further provided with simple access means for replacement of the filter elements. Additionally, the combination of the enclosure above described with an enclosure for housing all compressor control system components, meters, etc.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
An inlet, filter and noise suppressor enclosure for a compressing system including, a compressor having a suction inlet and a discharge outlet comprising, housing means forming a chamber having sound absorbing means lining the chamber, said chamber having an inlet for air or gas to be compressed and an outlet connected to the suction inlet for the compressor, filter means in the chamber in communication with said inlet to filter air and gas to be compressed entering through said inlet to the chamber, and by-pass means connected to said housing and in communication with said chamber and connected to the discharge outlet of the compressor for passing compressed air or gas from the discharge of said compressor back through the chamber for recycling the same back to the inlet of said compressor.
Claim 2
Dependent Claim
132 words
An inlet, filter and noise suppressor enclosure for a compressing system including, a compressor having a suction inlet and a discharge outlet comprising, housing means forming a chamber having sound absorbing means lining the chamber, said chamber having an inlet for air or gas to be compressed and an outlet connected to the suction inlet for the compressor, filter means in the chamber in communication with said inlet to filter air and gas to be compressed entering through said inlet to the chamber, and by-pass means connected to said housing and in communication with said chamber and connected to the discharge outlet of the compressor for passing compressed air or gas from the discharge of said compressor back through the chamber for recycling the same back to the inlet of said compressor.
Claim 3
Dependent Claim
35 words
In an inlet, filter and noise suppressor enclosure as claimed in claim 1, including muffler means in said chamber to silence air passed thereto and through said chamber to the suction inlet of the compressor.
Claim 4
Dependent Claim
42 words
In an inlet, filter and noise suppressor enclosure as claimed in claim 1 including, a muffler, said muffler having its inlet connected to the by-pass means and disposed to extend into and to pass by-passed compressed air or gas into the chamber.
Claim 5
Dependent Claim
74 words
In an inlet, filter and noise suppressor as claimed in claim 3 when the muffler is an elongated member including, a relatively small inlet opening in communication with the compressed air or gas discharged through the by-pass means, a muffling chamber spaced from said inlet, transverse convoluted passage means disposed between the inlet and the muffling chamber, and outlet means for the muffling chamber to pass by-passed compressed air or gas to the chamber.
Claim 6
Dependent Claim
219 words
A composite filter, noise suppressor and control enclosure for a compressing system including,a compressor having a suction inlet and a discharge outlet comprising, housing means having an upper section and a lower sectiOn disposed in spaced relation to each other to provide an instrument panel section therebetween, said upper section forming an inlet space having a partition dividing said inlet space into an outer inlet chamber and an inner inlet and by-pass chamber, said partition having an opening to provide communication between said outer inlet chamber and said inner inlet and by-pass chamber, filter means connected to said partition and disposed in said opening whereby air or gas delivered from any suitable source to said outer inlet chamber will be filtered as it passes to said inner inlet and by-pass chamber, said inner inlet and by-pass chamber having a discharge outlet communicating with the suction inlet of the compressor, sound absorbing means lining said inner inlet and by-pass chamber, and by-pass means connected between the discharge outlet of said compressor and the upper section of the housing means for communication with said inner inlet and by-pass chamber to by pass compressed air or gas from the discharge outlet of said compressor to said inner inlet and by-pass chamber for recycling therethrough back to the suction inlet of the compressor.
Claim 7
Dependent Claim
219 words
A composite filter, noise suppressor and control enclosure for a compressing system including,a compressor having a suction inlet and a discharge outlet comprising, housing means having an upper section and a lower sectiOn disposed in spaced relation to each other to provide an instrument panel section therebetween, said upper section forming an inlet space having a partition dividing said inlet space into an outer inlet chamber and an inner inlet and by-pass chamber, said partition having an opening to provide communication between said outer inlet chamber and said inner inlet and by-pass chamber, filter means connected to said partition and disposed in said opening whereby air or gas delivered from any suitable source to said outer inlet chamber will be filtered as it passes to said inner inlet and by-pass chamber, said inner inlet and by-pass chamber having a discharge outlet communicating with the suction inlet of the compressor, sound absorbing means lining said inner inlet and by-pass chamber, and by-pass means connected between the discharge outlet of said compressor and the upper section of the housing means for communication with said inner inlet and by-pass chamber to by pass compressed air or gas from the discharge outlet of said compressor to said inner inlet and by-pass chamber for recycling therethrough back to the suction inlet of the compressor.
Claim 8
Dependent Claim
26 words
In the composite enclosure as claimed in claim 5 including muffler means in said inner inlet and by-pass chamber for silencing air or gas passing therethrough.
Claim 9
Dependent Claim
61 words
In the composite enclosure as claimed in claim 5 including a partition in the upper section of the housing means forming, a blow off chamber, said by-pass means disposed to communicate with the blow off chamber, and outlet means in said partition to pass blow off air or gas from the blow off chamber to the inner inlet and by-pass chamber.
