A horizontal type scroll compressor includes a motor housing with a driving motor therein, a main scroll coupled to one side of the motor housing and having a fixed wrap for forming compression chambers, an orbiting scroll having an orbiting wrap and coupled to a crankshaft inserted through the main scroll, the orbiting scroll forming 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, and a front housing hermetically coupled to the main scroll. With the configuration, the number of components and assembly parts may be reduced, resulting in reduction of fabricating costs. Also, an inclination of the orbiting scroll can be prevented as the crankshaft is inserted through the fixed wrap and the orbiting wrap.

Horizontal type scroll compressor

Disclosed is a scroll compressor. As two side surfaces of a rotation preventing member are formed to be flat with keys, the rotation preventing member, a main frame, and an orbiting scroll may be easily processed and partial frictions and noise due to the keys may be prevented. Furthermore, since the orbiting scroll is entirely and stably supported by a ring portion of the rotation preventing member, the occurrence of a tilting moment of the orbiting scroll may be reduced. This may enhance the stability and the performance of the scroll compressor.
