Abstract
The reciprocating piston compressor has several parallel cylinder-piston units () in a common compressor casing () and whose pistons () are moved by a rotary wobble plate () by means of a coupling bracket () surrounding sliding pads (). For modifying the wobble plate inclination as a result of a regulated pressure in the compressor casing it is swivellably held by two articulated brackets () on a recess () of the drive shaft (). Together with the recess () and the spacing between the bilateral connection points to the wobble plate (), said articulated brackets () form a four-bar linkage, whose geometry ensures a functionally correct swivelling movement. The four joints (to) of the four-bar linkage are formed by uniaxial swivel joints, whose low frictional resistance leads to an improved control behaviour on controlling the delivery rate of the compressor.
