Abstract
A scroll compressor includes a feature for location of a housing shell section off of one of the scroll compressor bodies. According to this aspect, a scroll compressor comprises a housing including a shell section; scroll compressor bodies having respective bases and respective scroll ribs that project from the respective bases and which mutually engage about an axis for compressing fluid; and a drive unit operative to facilitate relative movement between the scroll compressor bodies. The shell section is located axially relative to a remainder of the housing off of one of the scroll compressor bodies.
Claims26
A scroll compressor, comprising:
- a housing including a shell section;
- scroll compressor bodies having respective bases and respective scroll ribs that project from the respective bases and which mutually engage about an axis for compressing fluid;
- a drive unit operative to facilitate relative movement between the scroll compressor bodies;
- wherein the shell section is located at an axial location relative to a remainder of the housing via contact between an inner surface of the shell section and a radially peripheral surface of one of the scroll compressor bodies;
- and
- a seal sealing between said one of the scroll compressor bodies and the shell section, the seal axially between the drive unit and the said axial location, wherein the shell section axially abuts one of the scroll compressor bodies above the seal.
A method of making a scroll compressor, comprising:
- assembling scroll compressor bodies having respective bases and respective scroll ribs that project from the respective bases and which mutually engage about an axis for compressing fluid;
- assembling a housing shell section over the scroll compressor bodies;
- limiting axial movement of the housing shell section via contact between an inner surface of the housing shell section and a radially peripheral surface of one of the scroll compressor bodies;
- securing the housing section to a remainder of a housing;
- sealing the housing shell section with one of the scroll compressor bodies below said limiting.
A scroll compressor, comprising:
- a housing including a shell section;
- scroll compressor bodies, including a fixed scroll compressor body and a movable scroll compressor body, having respective bases and respective scroll ribs that project from the respective bases and which mutually engage about an axis for compressing fluid;
- a drive unit operative to facilitate relative movement between the scroll compressor bodies;
- wherein the shell section axially abuts the fixed scroll compressor body through a step region in the shell section, wherein the shell section includes a generally cylindrical inner periphery and the step region is formed along the generally cylindrical inner periphery to include a larger diameter region and a smaller diameter region joined by a radially extending abutment region, the abutment region being defined between the larger and smaller diameter regions, the step region being formed by the thinning of a wall thickness of the shell section.
