Abstract:
A rotation shaft of a scroll compressor that includes an oil flow path formed therein, an upper frame support portion which is inserted into an upper frame, a boss insertion portion which is recessed from an upper surface of the upper frame support portion for insertion of the boss portion, and an oil residual groove which is recessed at a predetermined depth from a bottom portion of the boss insertion portion.
Abstract:
A scroll compressor is provided that may include a first scroll, a second scroll that defines a plurality of compression chambers together with the first scroll, the second scroll having a discharge hole that communicates with a compression chamber among the plurality of compression chambers, a back pressure plate that defines a back pressure chamber to accommodate a refrigerant discharged from the discharge hole, a floating plate to define the back pressure chamber, and a sealing member to prevent the refrigerant from flowing between a first surface, which may be a sliding surface of the floating plate, and a second surface, which may face the first surface, of the back pressure plate. The sealing member may include a seal cover that contacts the other one of the first and second surfaces, and a seal, a portion of which may be accommodated in the seal cover. The seal cover may have a friction coefficient less than a friction coefficient of the seal.
Abstract:
A sealing member, a scroll compressor, and a method for manufacturing a sealing member for a scroll compressor are provided. The scroll compressor may include a casing in which a rotational shaft may be provided, a discharge cover fixed to an 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 provided on the first scroll to define a plurality of compression chambers together with the first scroll, the second scroll having an intermediate pressure discharge hole that communicates with a compression chamber of the plurality of compression chambers having an intermediate pressure, a back pressure plate provided on the second scroll, the back pressure plate having an intermediate pressure suction hole that communicates with the intermediate pressure discharge hole, a floating plate movably provided at a side of the back pressure plate to define a back pressure chamber together with the back pressure plate, and a sealing member provided between a surface of the back pressure plate and a surface of the floating plate to prevent a refrigerant from leaking from the back pressure chamber. The sealing member may include a sealing body, and at least one protrusion provided at an incline with respect to a central line that extends in a horizontal direction of the sealing body.
