CA 2221505
A compressor housing and method of manufacture and assembly are disclosed. The compressor housing includes a cylinder block and a front housing. An annular projection is formed on the front end of the cylinder block. An annular groove is formed on the rear end of the front housing. The cylinder block and the front housing are secured to each other to prevent the front housing from being displaced in relation to the cylinder block by engaging the annular projection with the annular groove. A gasket is located between the front end of the cylinder block and the rear end of the front housing secured to each other to seal between the cylinder block and the front housing. This compressor and its method of manufacture reduce the amount of misalignment between a shaft bore in the cylinder block and a shaft bore in the front housing, which improves the performance of the compressor.
L'invention concerne une enveloppe de compresseur ainsi qu'une méthode de fabrication et d'assemblage. L'enveloppe du compresseur comprend un bloc-cylindres et un logement avant. Une saillie annulaire est formée à l'extrémité avant du bloc-cylindres. Une rainure annulaire est formée à l'extrémité arrière du logement avant. Pour empêcher que le logement avant ne se déplace par rapport au bloc-cylindres, le bloc-cylindres et le logement avant sont fixés l'un à l'autre par engagement de la saillie annulaire dans la rainure annulaire. Une garniture est placée entre l'extrémité avant du bloc-cylindres et l'extrémité arrière du logement avant fixés l'un à l'autre pour assurer l'étanchéité entre le bloc-cylindres et le logement avant. Avec ce compresseur et sa méthode de fabrication, on réduit le désalignement entre un alésage d'arbre dans le bloc-cylindres et un alésage d'arbre dans le logement avant, ce qui permet d'améliorer le rendement du compresseur.
