Abstract
In a scroll compressor, a discharge chamber is provided in an inner space of a back pressure chamber inner wall, a discharge port is provided inside the discharge chamber, a bypass hole is provided around the discharge port, and a communicating recess portion allowing the discharge chamber to communicate with the bypass hole is provided on an inner circumferential surface of the back pressure chamber inner wall forming the discharge chamber. Through this, the bypass hole may be easily configured in addition to the discharge port, thereby increasing an operation range of the compressor and suppressing overcompression.
Claims24
A scroll compressor comprising:
- an orbiting scroll including an orbiting wrap positioned at a surface of an orbiting end plate, the orbiting scroll being coupled to a rotation shaft;
- and
- a non-orbiting scroll including:
- a non-orbiting wrap positioned at a surface of a non-orbiting end plate, the non-orbiting wrap being configured to engage the orbiting wrap to thereby define a compression chamber,
- a back pressure chamber part defining a back pressure chamber at an opposite surface of the non-orbiting end plate, and
- a discharge chamber defined at the back pressure chamber part and being in fluid communication with the compression chamber,
- wherein a discharge port is defined at the non-orbiting scroll and enables fluid communication between the compression chamber and the discharge chamber, and
- wherein a bypass hole is defined around the discharge port and enables fluid communication between a first portion of a compression chamber and the discharge chamber, the first portion of the compression chamber having a pressure lower than a pressure of a second portion of the compression chamber that is in fluid communication with the discharge port, and
- wherein a communicating recess portion is provided at an inner circumferential surface of the discharge chamber and enables fluid communication between the discharge chamber and the bypass hole.
