ROTARY COMPRESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17983566 titled 'ROTARY COMPRESSOR
Simplified Explanation
The patent application describes a rotary compressor with a back pressure pocket that helps support a vane and reduce vibration noise and wear between the vane and the cylinder. It also prevents leakage between compression chambers and delays in startup.
- Rotary compressor with a back pressure pocket closest to the discharge port
- Back pressure pocket is radially spaced from the inner circumferential surface of a bearing hole
- Back pressure pocket communicates with the inner space of a casing through a back pressure passage
- Supports a vane passing near a reference point and forms a discharge pressure or super discharge pressure
- Reduces chattering of the vane and vibration noise
- Suppresses wear between the vane and the cylinder
- Enhances compression efficiency
- Prevents leakage between compression chambers
- Prevents delay in initial startup of the compressor
Original Abstract Submitted
A rotary compressor is disclosed. A back pressure pocket among a plurality of back pressure pockets closest to a discharge port disposed in at least one of main bearing or sub bearing is radially spaced from an inner circumferential surface of a bearing hole, and communicates with an inner space of a casing through a back pressure passage formed through at least one of the main bearing or the sub bearing. Accordingly, the back pressure pocket closest to the discharge port may strongly support a vane passing near a reference point toward a cylinder while forming a discharge pressure, or a super discharge pressure higher than the discharge pressure. This may suppress or prevent chattering of the vane near the reference point to reduce vibration noise while suppressing or preventing wear between the vane and the cylinder to enhance compression efficiency. This may also suppress or prevent leakage between compression chambers, thereby preventing delay of initial startup of the compressor.
