Abstract: A composite pad including: a silicone foam; an adhesive layer; and an outer layer, in which the adhesive layer includes a binder and a reactive filler that undergoes a dehydration reaction at a temperature equal to or higher than 100° C., the binder has a hardness in a range of a penetration hardness of 90 to a Shore 00 hardness of 40, the reactive filler is included in an amount of 50 to 300 parts by weight based on 100 parts by weight of the binder, and a thickness of the adhesive layer is in a range of 40 ?m to 400 ?m.

Abstract: Disclosed is a scroll compressor. The scroll compressor may comprise: a retainer block inserted into a block insertion groove of a non-orbiting scroll; and a block support member that is provided between the retainer block and a back pressure chamber assembly facing same and supports the retainer block toward the non-orbiting scroll. Accordingly, a bypass valve that suppresses overcompression of a compression chamber is not fastened to a non-orbiting end plate, and thus the non-orbiting end plate can be formed thin. Also, the length of a bypass hole decreases as the non-orbiting end plate becomes thinner, thus reducing the dead volume in the bypass hole. In addition, the retainer block can be fixed tightly and securely to the block insertion groove of the non-orbiting scroll.

Abstract: A scroll compressor may include a block insertion groove recessed by a predetermined depth into a rear surface of a non-orbiting scroll to accommodate a discharge port and at least one bypass hole, and a retainer block having at least one bypass valve to open and close the at least one bypass hole may be fixedly inserted into the block insertion groove. Accordingly, the at least one bypass valve that suppresses or prevents overcompression in a compression chamber is not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be formed thin. As the non-orbiting end plate is reduced in thickness, a length of the at least one bypass hole may be reduced, thereby decreasing a dead volume in the at least one bypass hole.
