Abstract
In a cylinder piston device, a piston unit is fixed to a piston rod member within a cavity defined by a cylinder member. The piston unit is provided with a piston ring supporting face, which is directed substantially in a radially outward direction towards the inner circumferential surface of the cylinder member. A piston ring member with a radially inner circumferential face and a radially outer circumferential face is supported by its radially inner circumferential face on said piston ring supporting face and engages by its radially outer circumferential face the inner circumferential surface of the cylinder member. The piston ring member is provided with at least one radially inward directed projection extending in the radially inward direction beyond the radially inner circumferential face, the projection axially engaging a securing face of the piston unit, and the securing face extending radially inward of the piston ring supporting face.
