Using slider mate with assembly pattern (piston in cylinder problem)

dejan_pavicevic

Does anyone know how to solve the following problem in the simplest way:

If we have a cylinder and there is a piston that slides along the axis (with the set mate - slider). How to modulate the number of cylinders and pistons with the help of a linear or circular pattern so that the mate - slider is retained, but that the position of the pistons from the beginning of the cylinder is not the same (the pistonare not at the same position)?

I don't know if this is what you're going for, but it may give you some ideas.

It's about a kind of piston pump (with a cam instead of a crankshaft)!
On the sketch is a cam, pump body with a cylinder and a piston inside the cylinder. On the basis of this sketch in the part studio was made a all parts and inserted into the assembly. I made a mate connection between the one piston and the cylinder (slider mate) and between cam and the piston (tangent mate)! And it works. I have animation.
When I increase the number of cylinders with the circular pattern and try to increase number of piston also with circular pattern I lose the connection between the cam and pistons. All piston move as original and do not follow the cam.

You may not be able to pattern, try replicate instead.

It make sense that a pattern would follow the seed part's relative position.
