Spiral compressor with running sleeves locked axially but able to rotate

A spiral compressor comprising:

• a stationary spiral element with a stationary spiral wall;
• a rotating spiral element with a rotating spiral wall arranged on a rotatable plate and which is engaged with the stationary spiral wall wherein several compression working spaces are formed;
• a guide means intended for guiding the rotating spiral element and with at least two guiding pins arranged in a stationary manner;
• and
• at least two recesses formed on a back of the rotating spiral element with running sleeves which are inserted therein in a radially movable manner, in which the guiding pins arranged in the stationary manner are received such that the inner surface of the running sleeves, during rotation of the rotating spiral element, rotates about a circumference of the guiding pins, wherein a lock is formed in each of the recesses which prevents an axial protrusion of the running sleeves out of the recesses, wherein the recesses have an undercut at a side of an inner circumference in which an edge region of the inserted running sleeves is deformed by beading or crimping.
