ABSTRACT:
A hydraulic cylinder has a pressure chamber delimited on one side by a piston accommodated in a longitudinally displaceable manner in a cylinder housing, on the other side by a housing bottom of the cylinder housing, and radially outwards by a circumferential wall of the cylinder housing, wherein the pressure chamber can be acted upon by a pressure medium via a pressure connection provided at the housing bottom in order to displace the piston in the cylinder housing. An insertion part is inserted in the pressure connection and has a channel section which communicates with the pressure connection and, in the installed position of the hydraulic cylinder, extends essentially in the vertical direction and opens into the pressure chamber in the vicinity of the circumferential wall of the cylinder housing. As a result, a hydraulic cylinder is provided which is compact and is designed in a simple manner, and which can be deaerated in a simpler manner compared to the prior art.
