Abstract
A pressure-medium cylinder does not have a component that dynamically seals the piston rod and can be well-cleaned safely from outside. The pressure-medium cylinder includes a cylinder housing, a piston, a piston rod, and a static end-position seal. The piston is axially movably disposed in the cylinder housing. The piston rod is connected to the piston and penetrates the cylinder housing toward an end face through an outlet opening. The piston rod has a stop surface extending radially from the piston rod in a piston rod portion disposed outside of the cylinder housing. The stop surface contacts the cylinder housing in an end position during retracting of the piston rod and thus sealingly covers and/or extends around a gap region or gap regions between the piston rod and an edge of the outlet opening.
