Hydropneumatic oil brake cylinder in wood working machines


Hydropneumatic oil brake cylinder in wood working machines

When wood is being drilled, it tends to splinter when the drill cuts through the wood surface. This can be avoided by regulating the cylinder movement through an oil brake cylinder. In this application, additionally a backstroke of the oil brake had to be realized, so common oil brakes could not be used. 

The rod of the oil brake is connected to the working pneumatic cylinders. During the forth stroke the oil of cylinder rod side is pushed through a throttle valve into the second cylinder pipe, which is equipped with a separator piston. It is pressurized by a constant pneumatic pressure. During back stroke the separator piston pulls the oil back to the main cylinder through a check valve.
