Verdichter mit einer Einrichtung zum Erfassen der Drehzahl

摘要

A fluid compressor, e.g. of the rotary scroll type or of the swashlate reciprocating-piston type, includes a mechanism for detecting the number of the rotations of the compressor. Magnetic flux, which leaks from an electromagnetic clutch 32 through a main drive shaft 2 to an asymmetric rotating member 26 located within the compressor housing, is sensed by a magnetic pickup 7 which is mounted and supported adjacent the rotation locus of the asymmetric rotating member. The magnetic pulses thereby produced in the pickup are representative of the number of rotations of the compressor.
