Abstract

Abstract A liquid seal compressor with control discs arranged transversely of the impeller and provided with a suction port and a pressure port, with a pressure chamber behind the pressure port and with a pressure delivery pipe on the pressure chamber, the pressure chamber being connected on one side with the pressure delivery pipe and on the other side with the pressure port, in which the part of the pressure chamber connected with the pressure delivery pipe is partially separated from the part connected with the pressure port by at least one wall descending into the zone of the pressure chamber filled with liquid.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 140 words
In a liquid seal compressor having an impeller, a pressure chamber at the outlet of the impeller and at least one control disc having a pressure port disposed between the impeller and the pressure chamber, the pressure port providing communication therebetween and a pressure delivery pipe communicating with the pressure chamber for delivery of the pressurized fluid, the improvement for reducing noise emanating from the pressure port from being transmitted to the pressure delivery pipe comprising a wall means within the pressure chamber partially separating the chamber into a first compartment communicating with the pressure port and a second compartment communicating with the pressure delivery pipe, said wall extending into the liquid in the bottom of the pressure chamber, whereby the magnitude of the sound waves emanating from the pressure port are substantially reduced before reaching the pressure delivery pipe.
Claim 2
Dependent Claim 140 words
In a liquid seal compressor having an impeller, a pressure chamber at the outlet of the impeller and at least one control disc having a pressure port disposed between the impeller and the pressure chamber, the pressure port providing communication therebetween and a pressure delivery pipe communicating with the pressure chamber for delivery of the pressurized fluid, the improvement for reducing noise emanating from the pressure port from being transmitted to the pressure delivery pipe comprising a wall means within the pressure chamber partially separating the chamber into a first compartment communicating with the pressure port and a second compartment communicating with the pressure delivery pipe, said wall extending into the liquid in the bottom of the pressure chamber, whereby the magnitude of the sound waves emanating from the pressure port are substantially reduced before reaching the pressure delivery pipe.
Claim 3
Dependent Claim 56 words
The improvement in a liquid steel compressor as claimed in claim 1 wherein the pressure port is in the upper part of said first compartment and the pressure delivery pipe is at the top of said second compartment, said wall extending downwardly from the top of the pressure chamber to a point below the pressure port.
Claim 4
Dependent Claim 51 words
The improvement in a liquid seal compressor as claimed in claim 1 wherein the pressure port is in the upper part of said first compartment and the pressure delivery pipe is substantially at the mid-height of said second compartment, said wall extending downwardly to a point below the pressure delivery pipe.
Claim 5
Dependent Claim 92 words
The improvement in a liquid seal compressor as claimed in claim 1 wherein the pressure port is in the upper part of said first compartment and the pressure delivery pipe is at the bottom of said second compartment, and wherein said wall means comprises a first wall extending downwardly from the top of the pressure chamber to a point below the pressure port and a second wall, behind said first wall in the direction of flow extending upwardly from the bottom to a point above the lower edge of said first wall.
Claim 6
Dependent Claim 91 words
The improvement in a liquid seal compressor as claimed in claim 1 wherein the pressure port is in the lower part of said first compartment and the pressure delivery pipe is at the top of said second compartment and wherein said wall means comprises a first wall extending upwardly from the bottom of pressure chamber to a point above the pressure port and a second wall, behind said first wall in the direction of flow, extending downwardly from the top to a point below the upper edge of said first wall.
Claim 7
Dependent Claim 51 words
The improvement in a liquid seal compressor as claimed in claim 1 wherein the pressure port is in the lower part of said first compartment and the pressure delivery pipe is substantially at the mid-height of said second compartment, said wall extending downwardly to a point below the pressure delivery pipe.
Claim 8
Dependent Claim 84 words
The improvement in a liquid seal compressor as claimed in claim 1 wherein the pressure port is in the lower part of said first compartment and the pressure delivery pipe is at the bottom of said second compartment and wherein said wall means comprises a first wall extending upwards to a point above the pressure port and a second wall, in front of said first wall in the direction of flow, extending downwardly to a point below the upper edge of said first wall.
Claim 9
Dependent Claim 29 words
The improvement in a liquid seal compressor as claimed iN claim 1 wherein at least one portion of said wall means comprises an extension of the pressure delivery pipe.
Claim 10
Dependent Claim 19 words
The improvement in a liquid seal compressor as claimed in claim 1 wherein said wall means comprises a pipe.
