Abstract
A scroll fluid machine comprises a housing, a driving shaft, a fixed scroll fixed to the housing, and an orbiting scroll. A gas introduced from the outer circumference of the housing is compressed towards the center of the housing with revolution of the orbiting scroll by the driving shaft. The compressed gas is discharged through a discharge hole extending from the center outward in a radial direction. A silencer fits in the discharge hole to prevent noise caused by discharge of the gas.

A scroll fluid machine comprising:
- a housing;
- a driving shaft having an eccentric axial portion at one end and extending axially of the housing from a center;
- an orbiting scroll comprising an orbiting end plate having an orbiting wrap and being rotatably mounted to the eccentric axial portion;
- a fixed scroll fixed to the housing and comprising a fixed end plate having a fixed wrap and a discharge hole extending radially, a gas sucked from an outer circumference of the housing being compressed toward a center of the housing in a sealed chamber formed between the orbiting wrap and the fixed wrap to discharge the compressed gas via the discharge hole;
- and
- a silencer fitting in the discharge hole of the fixed end plate.
