Muhammad,
Antonius suggested a neat way to do this is by linking a datum point to a datum curve.
I projected a circle 150mm diameter onto the surface of the swash plate to create the datum curve. A datum point was added to the end of the piston rod.
The swashplate rotates on a 'pin' connection and the piston uses a 'slider' connection. When the piston rod was assembled, a second 'slot' constraint was added using the datum curve on the swash plate (CTRL+ left click both halves of the curve) and the datum point on the end of the piston rod.
To animate the assembly I went into Mechanism and added a servo motor (velocity 720 degrees/sec) to the swashplate spindle. I then created a new analysis lasting one secondhich shows two full revolutionsi . After running the analysis, the playback was captured as an mpg. I left the datum curve visible in the video below.
Let us know how you get on.
