    摘要： A safety catch device for elevator cars guided on at least one guide rail includes a braking device acting on the at least one guide rail for braking the elevator car and a control device for controlling the braking force of the braking device in dependence on the load and/or deceleration. The control device includes a control mass which is influenced by the acceleration of the elevator car and a brake spring which is deflected in accordance with the position of the control mass. The brake spring is coupled to the control mass and the braking device in such a way that a reduced braking force is applied by the braking device on the at least one guide rail in the case of a high deceleration of the elevator car and an increased braking force is applied by the braking device on the at least one guide rail in the case of a lower deceleration of the elevator car.

    摘要： A pneumatic motor having a plurality of cylinders, with each cylinder having an expansion chamber (15), defined in part by a piston plate (2); and a diversion chamber (16) which is divided into two chambers by a slide plate (11), with the diversion chambers connected to a pressure supply line (27) and to a pressure diversion line (28). The piston plate is connected to a piston rod (5) by a lock (3). The expansion chamber holds an amount of compressed air held constant throughout the operation cycle. Expansion of the expansion chamber moves the piston plate and piston rod (5) to rotate a crankshaft (5a). At the end of the expansion stroke, the piston rod is disconnected from the piston plate. The expansion chamber is compressed by pressurizing the diversion chamber below the slide plate (11), forcing the slide plate and push rods (7) upwards, which pushes the piston plate upwards, until the piston plate can be held at a top position by a lock (3'). The diversion chamber below the slide plate is pressurized by pressurized air from diversion chambers of cylinders in which the expansion chamber has been compressed, along with supplemental air from a compressor (30).
