SCROLL COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18100712 titled 'SCROLL COMPRESSOR
Simplified Explanation
The abstract describes a scroll compressor with a unique design to accommodate a discharge port and bypass holes. It includes a retainer block with a bypass valve that opens and closes the bypass holes. The bypass valve is fixed to the retainer block, not the non-orbiting end plate, allowing for a reduction in the thickness of the end plate. This results in shorter bypass holes and discharge port, reducing dead volume.
- The scroll compressor has a block insertion groove on the non-orbiting scroll to accommodate a discharge port and bypass holes.
- A retainer block with a bypass valve is inserted into the block insertion groove.
- The bypass valve is fixed to the retainer block, not the non-orbiting end plate.
- This design allows for a reduction in the thickness of the non-orbiting end plate.
- The reduced thickness of the end plate shortens the bypass holes and discharge port.
- Shorter bypass holes and discharge port decrease the dead volume in the compressor.
Potential Applications
- Air conditioning systems
- Refrigeration systems
- Heat pumps
- Industrial compressors
Problems Solved
- Overcompression of the compression chamber
- Dead volume in the bypass holes and discharge port
Benefits
- Reduced thickness of the non-orbiting end plate
- Shorter bypass holes and discharge port
- Decreased dead volume in the compressor
Original Abstract Submitted
A scroll compressor is provided, the scroll compressor having a block insertion groove recessed by a predetermined depth into a rear surface of a non-orbiting scroll to accommodate a discharge port and a plurality of bypass holes, and a retainer block having a bypass valve that opens and closes the plurality of bypass holes fixedly inserted into the block insertion groove. The bypass valve may be fixed to a first axial side surface of the retainer block facing the block insertion groove. Through this, the bypass valve that suppresses or prevents overcompression of a compression chamber is not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. This may shorten lengths of the plurality of bypass holes and the discharge port by the reduced thickness of the non-orbiting end plate, thereby decreasing a dead volume in the plurality of bypass holes and the discharge port.
