Title: Twin helical rotors for installation in displacement machines for compressible media
Inventor: BECHER ULRICH
IPC: F04C18/16
Filed: 1999-10-01
Abstract: In prior art embodiments of displacement machines for compressible media, single thread twin helical rotors function with a continuously diminishing gradient to obtain internal compression. In some cases, this effect is amplified or superseded by the variation of the front profiles. The demand for compact pumps with rotors which are as a short as possible and the frequent process-related demand for quicker disassembly of the housing for cleaning purposes place limits on the wrapping angle or on the variation of the front profiles, which in turn leads to extreme gradient ratios or to insufficient compression rates. The invention solves these problems by using helical rotors (2) with an optimized, non-monotonous gradient (.DELTA.w1, .DELTA.w3) and an optional front profile variation with constant diameters. The displacement capacity is improved without altering the space requirements, and compression rates of 3.0 and more are easily attained using only four wrappings. Displacement machines equipped with twin helical rotors of this type offer optimal ratios with regard to energy demands, temperature, installation space and servicing, and can be used in the fields of chemicals and semiconductor technology.
