A scroll compressor is provided. The scroll compressor has a housing, a partition plate, a rack, a movable scroll plate, a stationary scroll plate and a pressure relief low-speed rotation structure. The partition plate is in the interior of the housing and divides the interior of the housing into a suction space and a discharge space, and has a first through to communicate the suction space with the discharge space. The rack is in the suction space and spaced apart from the partition plate. The movable scroll plate is movably provided on the rack. The stationary scroll plate is provided on the rack and cooperates with the movable scroll plate, and has a second through hole communicating with the discharge space. The pressure relief low-speed rotation structure is provided on the stationary scroll plate and configured to communicate the second through hole with the discharge space.

Scroll compressor with a pressure relief low-speed rotation structure

A scroll structure and a compressor are provided. The scroll structure has a first scroll plate, a second scroll plate matching the first scroll plate, a back pressure plate and a floating plate. The first scroll plate and the second scroll plate can move relative to each other. A recess is provided at one end of the second scroll plate facing away from the first scroll plate. A first through hole is provided on the second scroll plate. The back pressure plate is arranged in the recess. A gap is provided between the back pressure plate and a side wall of the recess. The floating plate is movably arranged on the back pressure plate. The floating plate covers the gap. A first chamber is formed among the second scroll plate, the back pressure plate and the floating plate. The first through hole is in communication with the first chamber.

Scroll structure and compressor with back pressure plate and floating plate

An air injection enthalpy-increasing scroll compressor is provided. The compressor has a main frame, a movable scroll plate and a stationary scroll plate. The movable scroll plate has a movable plate end plate and a movable scroll wrap arranged on a side end face of the movable plate end plate. A back pressure chamber is defined between the movable plate end plate and the main frame. The stationary scroll plate has a fixed scroll end plate and a stationary scroll wrap arranged on a side end face of the fixed scroll end plate. The stationary scroll wrap and the movable scroll wrap are engaged with each other to form crescent-shaped compression cavities. The movable scroll plate and the stationary scroll plate are provided with medium pressure passages that, during the rotation of the movable scroll plate, communicate the compression cavity with the back pressure chamber.
