Filed:

Jul 31, 2006

Appl. No.:

11/461079

Inventors:

Paul A. Huber - Boones Mill VA, US
Paul Nemit, Jr. - Roanoke VA, US

Assignee:

Johnson Controls Technology Company - Holland MI

International Classification:

F16K 15/06

US Classification:

13751617, 137544, 13762537, 137528

Abstract:

A backflow and strainer device is presented. The device is a unitary unit that prevents backflow of fluid gas in a compressor and prevents dirt particles and debris from entering the compressor, thereby damaging the components. A valve mechanism moves between an open position and a closed position to either allow or prevent fluid gas from flowing into the compressor. A mesh portion is disposed in the device to trap all dirt particles and debris to prevent them from entering the compressor. The valve mechanism responds to the higher and lower pressures associated with the operation and shutdown of compressors.

International Classification:

F04B 39/00
F01N 13/00

US Classification:

417312, 417543, 181241

Abstract:

An attenuating apparatus for use with a positive displacement compressor. The device includes a bore formed in a housing of the compressor, the bore being positioned at an angle to a discharge chamber of the compressor and in fluid communication with the compressor discharge chamber. A plug is positioned within the bore, the plug movable within the bore to a preselected position. The plug has a first end in contact with a gas from the compressor discharge chamber and a second, opposite end being accessible from an exterior of the housing. A seal is positioned between the plug and the bore to seal an interface between the plug and the bore to prevent leakage of a gas from the compressor discharge chamber along the interface. The plug is lockable within the bore at the preselected position. The preselected position of the plug within the bore determines a bore length in fluid communication with the compressor discharge chamber, which attenuates sound from gas pulsations resulting from discharge of compressed gas from the operation of the compressor.

International Classification:

F04D 25/06
F04D 29/40

Abstract:

A semi-hermetic compressor for ammonia service includes a compressor portion and a motor encased in an airtight housing portion. The compressor portion compresses ammonia. The motor includes a stator winding. Motor leads are connected to the field windings, and extend from the housing portion through a pass-through assembly. The pass-through assembly includes a base portion, a first isolation portion, a second isolation portion, a sealant and a cap portion. The base portion is inserted into the housing portion with an airtight seal. The first isolation portion is arranged to fit within an annular opening in the base portion. First and second isolation portions include apertures for a motor lead. Sealant is disposed between the isolation portions. A cap portion attaches to the base portion. An anti-rotation element prevents relative rotation there between.
