Modification for scroll wrap height of a scroll compressor

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
In order to obtain better axial hermetic seal of scroll compression chambers and hence a better performance for a scroll compressor, two modification methods for scroll wrap height are proposed based on the axial deformation of the scroll wrap. First, the design modification, which allows the scroll wrap height and its dimensional tolerances to be ...

The Geometry of the Scroll Compressor

SIAM Review, 2001
The scroll compressor is an ingenious machine used for compressing air or refrigerant; it was originally invented in 1905 by Léon Creux. The classical design consists of two nested identical scrolls given by circle involutes, one of which is rotated through $\text{180}^{\circ}$ with respect to the other. By specifying not a parametrization of the curve,

Analysis of Orbiting Scroll Overturning for Scroll Compressor

Applied Mechanics and Materials, 2012
Studies on leakage and friction have received considerable attention in scroll compressor, especially which between the fitting surface of orbiting scroll and fixed scroll, as they affect the scroll compressor performance. According to the scroll compressor working principle and structure, combined with the force model of the orbiting scroll, the ...

The effect of scroll wraps on the performance of scroll compressors

International Journal of Refrigeration, 1997
Abstract A number of geometrical curves have been used to form the wraps of scroll compressors. When the suction pressure, pressure ratio, scroll wrap height and thickness, and suction volume are constant, the effect of the involute curves of a cricle, square and line segment on the performances of the scroll compressor, such as geometrical ...

On the profile design of a scroll compressor

International Journal of Refrigeration, 1995
The scroll configuration plays a very important role in the design of a scroll compressor. Therefore, in the present paper, a general design process for the profile of a scroll compressor is proposed. The design process is developed based on geometric as well as kinematic considerations. It is general enough that not only a perfect meshing profile (PMP)
