Piston with piston rod

摘要

The piston (1) has a ball receptacle (14) for the rod head (4) of the piston rod (2) of a swash plate compressor. For absorbing particularly high pressures the rod head (4) has a relatively large diameter, so that the ball receptacle (14) extends close to the circumference of the piston (1). The piston wall (15) laterally surrounding the rod head (4) has a circumferential indentation (21) which, in the inwards direction, forms an uninterrupted undercut enclosing the spherical rod head (4).
