Abstract

PURPOSE: To prevent the abrasion on the surface of an end plate outer periphery at the start of an operation and the occurrence of a resultant mechanical loss by forming an annular groove on the operating chamber side surface of the end plate outer periphery of a rotary scroll and communicating multiple grooves extended to the outside and the inside in the radial direction to this annular groove.
CONSTITUTION: An annular groove 23 is formed on the operating chamber side surface of the outer periphery of the end plate 2a of a rotary scroll 2, and multiple grooves 24, 25 extended to the outside and the inside in the radial direction are communicated to this annular groove 23. According to this constitution, the oil in the back pressure chamber 20 of the rotary scroll 2 is easily guided to the annular groove 23, the groove 25 and an intake chamber via the groove 24, thus no oil exhaustion occurs on the outer periphery of the end plate 2a at the start of an operation of a scroll compressor, and the abrasion on this portion is reduced and a mechanical loss is also reduced.
