Scroll fluid apparatus having an inclined wrap surface

A scroll-fluid apparatus comprising:

• a fixed scroll component having a first end plate and a scroll wrap section installed on said first end plate and projecting therefrom;
• an orbital scroll component revolvably provided to face said fixed scroll component and having a second end plate and a scroll wrap section installed on said second end plate and projecting therefrom, to form a plurality of compression chambers between said scroll wrap section of said fixed scroll component and said scroll wrap section of said orbital scroll component;
• wherein at least one of said scroll wrap section of said fixed scroll component and said scroll wrap section of said orbital scroll component constitutes a profiled scroll wrap section;
• wherein said profiled scroll wrap section comprises an outer section of at least the outermost one turn of said profiled scroll wrap section, and first and second consecutive inclined sections extending between said outer section and an innermost end of said profiled scroll wrap section;
• wherein said outer section has a constant height along its entire length;
• wherein said first inclined section has a height which continuously linearly decreases from said outer section toward said second inclined section;
• wherein said second inclined section has a height which continuously linearly decreases from said first inclined section toward said innermost end of said profiled scroll wrap section;
• and
• wherein an angle of inclination of said first inclined section is different than an angle of inclination of said second inclined section, such that said height of said first inclined section decreases toward said second inclined section at a rate different than a rate at which said height of said second inclined section decreases toward said innermost end of said profiled scroll wrap section.
