Kind Code:
A1
Abstract:
A fixed scroll assembly (100) and a scroll compressor comprising the fixed scroll assembly (100). The fixed scroll assembly (100) comprises a fixed scroll part (110), at least two bypass inlet sections (111), piston chambers (121), bypass discharge channels (141), pistons (130), a connecting groove (125), a sealing assembly (160), and a bypass control device (150). The piston chambers (121) are respectively provided on the sides of the corresponding bypass inlet sections (111) opposite to a compression cavity and extend to an outer end surface (102b) of an end plate (102). Each piston (130) is housed in the corresponding piston chamber (121), and is configured to be movable between a sealing position and a release position; at the sealing position, the piston (130) covers the corresponding bypass inlet section (111) to prevent the bypass inlet section (111) from being communicated with the corresponding bypass discharge channel (141); and at the release position, the piston (130) is far away from the bypass inlet section (111) to allow the bypass inlet section (111) to be communicated with the bypass discharge passage (141). The connecting groove (125) is provided on the outer end surface (102b) and is configured to communicate the piston chambers (121) with each other. The sealing assembly (160) is configured to seal the connecting groove (125).
