SCROLL COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18109559 titled 'SCROLL COMPRESSOR
Simplified Explanation
The abstract describes a scroll compressor with a valve accommodating groove and a valve guide to control the bypass valves. The bypass valves are inserted into the valve guide and open and close the bypass holes to prevent overcompression in the compression chambers. This design allows for a thinner non-orbiting end plate and reduces the dead volumes in the bypass holes.
- A scroll compressor with a valve accommodating groove and a valve guide is provided.
- The valve accommodating groove is recessed into the rear surface of a non-orbiting scroll.
- A valve guide is placed between the rear surface of the non-orbiting scroll and the back pressure chamber assembly.
- Bypass valve guide holes are formed in the valve guide to accommodate the bypass valves.
- The bypass valves open and close the bypass holes to prevent overcompression in the compression chambers.
- This design allows for a thinner non-orbiting end plate.
- The reduction in thickness of the non-orbiting end plate leads to shorter bypass holes and decreased dead volumes.
Potential Applications
- Scroll compressors are commonly used in air conditioning systems, refrigeration units, and heat pumps.
- This innovation can be applied to various scroll compressor designs to improve their efficiency and performance.
Problems Solved
- Overcompression in compression chambers can lead to inefficiencies and damage to the compressor.
- The non-orbiting end plate in traditional scroll compressors may be too thick, resulting in larger dead volumes in the bypass holes.
- This design solves these problems by using a valve guide and bypass valves to control the bypass holes and prevent overcompression.
Benefits
- The thinner non-orbiting end plate reduces the dead volumes in the bypass holes, improving the overall efficiency of the compressor.
- The use of a valve guide allows for easier control and adjustment of the bypass valves.
- This design provides a more compact and efficient scroll compressor solution.
Original Abstract Submitted
A scroll compressor is provided. In the scroll compressor, a valve accommodating groove that accommodates a discharge port and bypass holes is recessed by a predetermined depth into a rear surface of a non-orbiting scroll, and a valve guide is disposed between the rear surface of the non-orbiting scroll and a rear surface of the back pressure chamber assembly facing the rear surface of the non-orbiting scroll. Bypass valve guide holes into which bypass valves that open and close the bypass holes are slidably inserted are formed in the valve guide. Accordingly, the bypass valves that suppress or prevent overcompression in compression chambers are not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. As the non-orbiting end plate is reduced in thickness, lengths of the bypass holes may be reduced, thereby decreasing dead volumes in the bypass holes.
