Abstract
A scroll compressor includes a frame holding an orbiting scroll configured to slide, a fixed scroll configured to form a compression chamber together with the orbiting scroll, and a shell accommodating the frame and the fixed scroll. The shell includes a first inner wall surface and a first protrusion protruding from the first inner wall surface to position the fixed scroll, and the fixed scroll is fixed to the first inner wall surface.
Claims18
A shell accommodating a frame holding an orbiting scroll configured to slide, and a fixed scroll configured to form a compression chamber together with the orbiting scroll, the shell comprising:
- a first inner wall surface to which the fixed scroll is fixed;
- a first protrusion protruding from the first inner wall surface to position the fixed scroll;
- a second inner wall surface to which the frame is fixed;
- and
- a second protrusion protruding from the second inner wall surface to position the frame,
- wherein the first inner wall surface is formed to have an inner diameter that is larger than an inner diameter of the second inner wall surface.
A scroll compressor, comprising:
- a frame holding an orbiting scroll configured to slide;
- a fixed scroll configured to form a compression chamber together with the orbiting scroll;
- and
- a shell accommodating the frame and the fixed scroll,
- the shell including a first inner wall surface, a first protrusion protruding from the first inner wall surface to position the fixed scroll, a second inner wall surface, and a second protrusion protruding from the second inner wall surface to position the frame,
- the fixed scroll being fixed to the first inner wall surface, and
- the frame being fixed to the second inner wall surface,
- wherein the first inner wall surface is formed to have an inner diameter that is larger than an inner diameter of the second inner wall surface.
A scroll compressor, comprising:
- a frame holding an orbiting scroll configured to slide;
- a fixed scroll configured to form a compression chamber together with the orbiting scroll;
- and
- a shell accommodating the frame and the fixed scroll,
- the shell including a first inner wall surface, a first protrusion protruding from the first inner wall surface to position the fixed scroll, a second inner wall surface, and a second protrusion protruding from the second inner wall surface to position the frame,
- the fixed scroll being fixed to the first inner wall surface, and
- the frame being fixed to the second inner wall surface,
- the shell includes
- a main shell with both ends opened,
- a first shell covering an opening port on one end side of the main shell, and
- a second shell covering an opening port on another end side of the main shell,
- a first positioning surface for positioning the fixed scroll is formed at a part of the first protrusion that is close to the first shell, and
- a second positioning surface for positioning the frame is formed at a part of the second protrusion that is close to the first shell,
- wherein a recess is formed in a direction to the second shell in at least one of a connecting portion on the first protrusion with the first inner wall surface and a connecting portion on the second protrusion with the second inner wall surface.
