Abstract:
A positioning foot having a hydraulic shock absorber with a fluid-filled hollow cylinder (210), in which a piston (220) that moves axially between an advanced, spring prestressed position and a retracted position. The piston separates a front axial fluid space (214) and a rear axial fluid space (215) from one another in the hollow cylinder. Both fluid spaces are connected to one another in a fluid exchanging fashion via at least one throttle opening (223) in the piston. The piston is rigidly connected to a piston rod (221), which passes through the front fluid space and abuts a fixed stop (218) in the retracted position, in which the volume of the rear axial fluid space is minimized and the volume of the front axial fluid space is maximized. The spring prestress is dimensioned so that the weight of the device body moves the piston dampingly into the retracted position.
