Abstract
By cutting-machining a side face of a scroll wrap with a non-rotational tool, swells in the perimeter direction have a smaller size. Thus, the leakage of compressed gas is prevented from being caused between side faces sliding to each other of the respective wraps of the stationary scroll and the slewing scroll. This configuration provides a scroll compressor that has a higher accuracy by which a high compression efficiency and low noise are realized.
Claims13
A scroll compressor comprising:
- a stationary scroll and a slewing scroll having an end plate and a scroll-like wrap raised from the end plate, respectively;
- an inhale opening provided at an outer periphery of the stationary scroll for inhaling fluid;
- a compression space provided by engaging the respective wraps to each other, the compression space for compressing the fluid inhaled from the inhale opening by reducing capacity thereof while moving from the outer circumference to a center part of the stationary scroll by a circular orbit motion of the slewing scroll;
- and
- a discharge opening provided at the center part for discharging the fluid compressed by the compression space,
- wherein at least any one of side faces sliding to each other of the respective wraps has a machining mark parallel to a surface of a corresponding one of the end plates.
