Abstract
The reciprocating piston compressor has several parallel cylinder-piston units (7, 8) in a common compressor casing (3) and whose pistons (8) are moved by a rotary wobble plate (11) by means of a coupling bracket (9) surrounding sliding pads (12). 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 (23, 24) on a recess (29) of the drive shaft (4). Together with the recess (29) and the spacing between the bilateral connection points to the wobble plate (11), said articulated brackets (23, 24) form a four-bar linkage, whose geometry ensures a functionally correct swivelling movement. The four joints (25 to 28) 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.
