Abstract:
A scroll compressor is provided, the scroll compressor having a block insertion groove recessed by a predetermined depth into a rear surface of a non-orbiting scroll to accommodate a discharge port and a plurality of bypass holes, and a retainer block having a bypass valve that opens and closes the plurality of bypass holes fixedly inserted into the block insertion groove. The bypass valve may be fixed to a first axial side surface of the retainer block facing the block insertion groove. Through this, the bypass valve that suppresses or prevents overcompression of a compression chamber is not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. This may shorten lengths of the plurality of bypass holes and the discharge port by the reduced thickness of the non-orbiting end plate, thereby decreasing a dead volume in the plurality of bypass holes and the discharge port.
Abstract:

Abstract:
A solar cell can include a substrate of a first conductive type; an emitter layer of a second conductive type opposite the first conductive type, and positioned on the substrate; a plurality of finger electrodes formed in a first direction, each finger electrode being electrically connected to the emitter layer; a plurality of first collector regions; a plurality of first electrodes positioned in a plurality of first collector regions and extending in the first direction from the plurality of finger electrodes; a plurality of second electrodes positioned in the plurality of first collector regions and formed in a perpendicular direction crossing the first direction; a plurality of third electrodes positioned in the plurality of first collector regions, connecting two neighboring first electrodes of the plurality of first electrodes and formed in the perpendicular direction; and a plurality of deletions positioned in the plurality of first collector regions. Furthermore, one of the plurality of second electrodes is positioned between a pair of the plurality of first electrodes.
Abstract:
A scroll compressor is provided that may include a block insertion groove to accommodate a discharge port and at least one bypass hole disposed in a rear surface of a non-orbiting end plate of a non-orbiting scroll, and a retainer block including at least one bypass valve to open or close the bypass hole inserted into the block insertion groove. The bypass hole may include a first bypass hole and a second bypass hole. The bypass valve may include a first bypass valve to open or close the first bypass hole and a second bypass valve to open or close the second bypass hole, and may be disposed between the block insertion groove and the retainer block facing the block insertion groove. Accordingly, the first and second bypass valves are not fastened to the non-orbiting end plate, which may allow the non-orbiting end plate to be made thin.
Abstract:
A scroll compressor is provided that may include a casing including a rotational shaft, a cover fixed inside of the casing to partition the inside of the casing into a suction space and a discharge space, a first scroll revolved by rotation of the rotational shaft, a second scroll disposed on or at one side of the first scroll to define a compression chamber together with the first scroll, the second scroll including a discharge, through which a refrigerant pressed in the compression chamber may be discharged, a switching device movably disposed on or at one side of the discharge to selectively open and close the discharge, a back pressure portion including a moving guide that accommodates at least a portion of the switching device, and a top surface that covers one side of the switching device; and an adhesion preventer that reduces a contact area between the switching device and at least a portion of the back pressure portion.
Abstract:
