A pressure medium-tight inductive pickup for a fluid control element has a pressure pipe composed of a non-magnetic material, a magnetic core received in the pressure pipe, connecting means at the open end of the pressure pipe for pressure-tight connection of the pressure pipe with the control element, a spool body surrounding the pressure pipe, a housing surrounding the spool body and having an axis, and an adjusting element for adjusting zero position of the pickup, wherein the spool body is axially displaceable on the pressure pipe and in the housing, and the adjusting element is formed as a worm drive adjustable from outside and arranged so that the spool body is coupled with the worm drive in a play-free manner in an axial direction.

A sliding vane compressor for use in refrigeration systems includes a rotatable hollow shaft, a cylindrical compressor rotor which surrounds the shaft, end covers enclosing the compressor rotor and a pair of vanes disposed within the rotor to compress a working medium entering the rotor. The compressor rotor and end covers have end faces in a contact area therebetween. At at least one of end faces of either rotor or end cover, a number of spirally-shaped grooves are formed curved in the direction of rotation of the rotor shaft. These grooves extend from the periphery of the respective end face toward the center thereof but short of said center to produce a flow preventing leakage of the working medium between the low pressure region and the high pressure region in the compressor.
