Abstract:
A fluid power cylinder comprising:a cylinder housing containing therein a piston receiving space in which a piston able to be moved by fluid actuation is arranged, which is kinematically coupled with a piston rod extending out at the front end of the cylinder housing, a control system housing mounted on the rear end of the cylinder housing, the system housing contains control components cooperating for control of fluid actuation of the piston, the control components including an electrically actuated valve means and furthermore electronic valve circuitry and/or electronic control circuitry cooperating in the electrical control of the valve means, the side of the control system housing has a plurality of access openings arranged about the periphery and closed by detachable housing covers, one opening being opposite to an electrical drive means of the valve means and a further access opening being arranged adjacent to the electronic valve circuitry and/or electronic control circuitry, electrical connection means provided externally on the control system housing for the supply of electrical control signals, which electrical connection means are connected in the control housing with electronic valve circuitry and/or electronic control circuitry, and fluid connection means provided externally on the control system housing for the supply of an actuating fluid, the electrical connection means are connected with the valve means, whence control ducts emerge, which extend in the wall of the cylinder housing to the piston receiving space.
