CylinderDouble Double cylinder model
	Cylinder Cylinder chamber
	CylinderDoubleFriction Same as CylinderDouble but with more friction types added, like Stribeck friction. This model also has external leakage.
	CylinderEqualAreaSpring Same as CylinderDoubleFriction but with springs that move the cylinder back to the center position

This package contains different types of cylinders. The cylinders have both hydraulic and mechanical connectors. The hydraulic ports can be connected to arbitrary hydraulic components, and the mechanical flanges can be connected to translational mechanical components from the Modelica Standard Library.
