Abstract
Abstract The silencer-separator described hereinafter includes a tank that has an inlet arranged to receive the discharge from a vacuum blower or the like, a discharge located at the opposite end of the tank, a partition located therebetween with hole extending therethrough to permit the gas to flow from the discharge of the blower to the discharge of the tank. At the lowermost end of the tank, there is provided a drain for the liquid that is separated as the air enters the tank from the blower. An overflow conduit extends from adjacent the lowermost portion of the tank, through the partition and is connected with the liquid drain. With the conduit arranged in this manner, water, which is used to seal the blower, is located in the conduit preventing sound, generated as the gas is discharged from the blower, from passing through the conduit to the atmosphere via the drain.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
An improved silencer-separator for liquid-sealed gas blowers or the like including a discharge and being provided with water injection means, said silencer-separator including: a hollow tank having an inlet in communication with the blower discharge, a gas outlet and a liquid drain near the lowermost portion of the tank; a partition between said inlet and outlet dividing said tank into a first chamber including the inlet and a second chamber including the outlet and the drain; a gas passageway in said partition located above the anticipated water level in the tank; an overflow conduit extending through said partition and having an entry end located in the first chamber adjacent the lower portion of the tank and below the water level when the blower is operating and having an outlet end, connected with said liquid drain; and, wherein said overflow conduit extends through said partition at a height measured from the lowermost portion of the entry end of the overflow conduit that is greater than the anticipated maximum pressure differential expressed in inches of water between said first chamber and atmospheric pressure.
Claim 2
Dependent Claim
181 words
An improved silencer-separator for liquid-sealed gas blowers or the like including a discharge and being provided with water injection means, said silencer-separator including: a hollow tank having an inlet in communication with the blower discharge, a gas outlet and a liquid drain near the lowermost portion of the tank; a partition between said inlet and outlet dividing said tank into a first chamber including the inlet and a second chamber including the outlet and the drain; a gas passageway in said partition located above the anticipated water level in the tank; an overflow conduit extending through said partition and having an entry end located in the first chamber adjacent the lower portion of the tank and below the water level when the blower is operating and having an outlet end, connected with said liquid drain; and, wherein said overflow conduit extends through said partition at a height measured from the lowermost portion of the entry end of the overflow conduit that is greater than the anticipated maximum pressure differential expressed in inches of water between said first chamber and atmospheric pressure.
Claim 3
Dependent Claim
231 words
An improved silencer-separator for liquid-sealed gas blowers or the like including a discharge and being provided with water injection means, said silencer-separator including: a hollow tank having an inlet in communication with the blower discharge, a gas outlet and a liquid drain near the lowermost portion of the tank; a partition between said inlet and outlet dividing said tank into a first chamber including the inlet and a second chamber including the outlet and the drain; a gas passageway in said partition located above the anticipated water level in the tank; an overflow conduit extending through said partition and having an entry end located in the first chamber adjacent the lower portion of the tank and below the water level when the blower is operating and having an outlet end, connected with said liquid drain; wherein said overflow conduit extends through said partition at a height measured from the lowermost portion of the entry end of the overflow conduit that is greater than the anticipated maximum pressure differential expressed in inches of water between said first chamber and atmospheric pressure; a drain passageway in said partition located adjacent the lowermost portion of said tank in communication with the liquid drain, said drain passageway being too small to permit full flow of the minimum sealing water injected into the blower; and, wherein said drain passageway is also connected with said overflow conduit.
