The invention relates to a method and to an apparatus for vibration compensation in a piston compressor, the piston compressor of which is driven by means of a crankshaft by a three-phase motor controlled by a frequency converter, wherein the current position the crankshaft of the piston compressor is determined, and based on this the frequency converter, a torque (M) for the three-phase motor is predetermined, which torque follows the load torque (M) of the piston compressor in order to reduce the vibration stimulation of the entire piston compressor.

Method and apparatus for vibration compensation in a piston compressor

The invention relates to a method and to a system for putting into service a brake system having specified approval prerequisites, in particular wherein the brake system is a pneumatic and/or hydraulic braking system, in particular a pneumatic and/or hydraulic braking system of a rail vehicle, wherein the control data set for the brake system is set on the basis of a real reference operation and a virtual test operation in such a way that the specified approval prerequisites are achieved.

Method for putting into operation a brake system with predefined approval specifications and system for putting into operation a brake system with predefined approval specifications

A crank drive arrangement of a piston compressor with a rolling bearing arranged on a crank pin of a crank shaft and to which a connecting rod is attached via an intermediate ring which interacts with apparatus for securing against rotation in relation to the connecting rod, wherein the apparatus for securing against rotation have a pin arrangement fastened in a play-free manner in the connecting rod by a thread and which comes into engagement in an interlocking manner in the intermediate ring via a play-exhibiting fit.

Crank-driven arrangement for a piston compressor

A control device for a brake system of a rail vehicle, wherein the brake system includes a friction bracket device which is dependent on frictional engagement. The control device determines a braking effect applied during a braking process on the basis of a brake pressure or brake current and at least one further parameter. Also disclosed are a brake system having such a control device and a method for determining a braking effect.

Determining a braking force for a rail vehicle

The invention relates to a piston arrangement for a dual-stage piston compressor, comprising a cranksbaft and several cylinders which house the operating piston. Said arrangement allows two or more low-pressure stages and at least one high-pressure stage to be formed. The invention is characterized in that the two or more low-pressure cylinders are arranged in relation to the high-pressure stage in such a way that said two or more low-pressure cylinders are in phase or are offset by less than &plusmn;15&deg; and compress in a position which is offset by 180&deg;&plusmn;20, in relation to one or more high-pressure cylinders.
