Hydraulic cylinder, particularly master cylinder for clutch releasing device in drive train of motor vehicle, has piston that is axially adjustable in cylinder housing by piston rod

摘要

The hydraulic cylinder (1) has a piston (3) that is axially adjustable in a cylinder housing (2) by a piston rod (4). A sensor system is provided with a sensor (S) for contactless distance measurement and position determination of the piston or the piston rod. The sensor is formed as an optical or opto-electronic component, which stands in active connection with the detection range (D) arranged on the piston or the piston rod.
