| description | The invention provides a scroll compressor which improves the efficiency of the compressor by suppressing refrigerant leakage on end plate sliding surfaces of a rotational scroll plate and a fixed scroll plate of the scroll compressor. The scroll compressor of the invention has an inhalation pressure guiding groove which is communicated with an inhalation chamber and is formed in the fixed end plate surface or the rotational end plate surface in an extending manner to the opposite side of the compressor chamber and guides the pressure into the inhalation chamber, and a back pressure guiding groove which is located in a position point symmetrical to inhalation pressure guiding groove relative to the center of fixed scroll teeth and is formed in the fixed end plate surface or the rotational end plate surface and guides the pressure of a back pressure chamber. A torque is generated opposite to a overturning moment according to a phase angle with a large overturning moment to reduce the gap between the end plate surfaces. Thus the leakage loss is effectively reduced, especially the scroll compressor is effectively suitable for the R32 refrigerant which is easily leaked. |
