Scroll compressor witha lubricant supply system and refrigeration cycle apparatus having the scroll compressor

A scroll compressor comprising

• a crank shaft having a lubricant channel which allows a lubricant to flow therethrough;
• an orbiting scroll attached to the crank shaft, the orbiting scroll including:
• a discoidal base plate,
• a cylindrical part that projects from one surface of the base plate,
• inner channels configured to allow the lubricant supplied thereto through the crank shaft to outwardly flow therethrough, the inner channels including a first inner channel and a second inner channel,
• one end of the second inner channel is connected to an inside of the cylindrical part and another end of the second inner channel penetrates the base plate to a radial outer side of the base plate, and
• an adjustment part is provided in the second inner channel and configured to adjust a flow amount of the lubricant flowing through the second inner channel;
• a frame having a thrust surface which slides against the orbiting scroll;
• a fixed scroll forming, together with the orbiting scroll, a compression space;
• and
• a bushing including a weight part provided outside the cylindrical part of the orbiting scroll and connecting the orbiting scroll and the crank shaft to each other,
• wherein an angle a formed between a line L1 that connects a hole of the second inner channel formed in a side of the base plate of the orbiting scroll and a center C of the base plate to each other and a line L2 that connects an outermost end part of a scroll body formed in the fixed scroll or the orbiting scroll and the center C of the base plate to each other is 10 degrees or smaller.
