Horizontal type scroll compressor

A horizontal type scroll compressor comprising:

• a casing having a motor housing and a front housing;
• a driving motor installed within an inner space of the motor housing and having a rotor;
• a crankshaft coupled to the rotor;
• a main scroll having a fixed wrap, and provided between the motor housing and the front housing;
• and
• an orbiting scroll having an orbiting wrap engaged with the fixed wrap of the main scroll and coupled to a crankshaft inserted through the main scroll, wherein the orbiting scroll forms a first compression chamber and a second compression chamber on an outer surface and an inner surface of the orbiting wrap while performing an orbiting motion, wherein a shaft coupling portion to which the crankshaft is inserted is formed through the orbiting scroll, wherein the orbiting scroll is accommodated within the front housing wherein a plurality of coupling bores is formed on the motor housing in a circumferential direction, and a plurality of through holes aligning with the plurality of coupling bores of the motor housing is formed through the main scroll and the front housing, respectively, and wherein the main scroll and the front housing are coupled to the motor housing using bolts inserted into the plurality of coupling bores through the plurality of through holes.
