Abstract
The supply of pressure medium to hydraulic or pneumatic cylinders is usually carried out by means of pressure medium lines which are connected to the heads of the cylinders by means of standardized connection threads. This method of supplying pressure medium requires a minimum wall thickness of the casing of the cylinder in the connection region. In order to permit secure attachment of the pressure medium lines even when the minimum thickness which is necessary for the use of the standardized connection thread is not present, the outside of the casing of the cylinder is flattened in the vicinity of the exit point of a duct provided for the supply of pressure medium. A connection plate which is provided with ducts for the pressure medium is secured to the flattened part of the casing, and the connection plate is provided with a port for a pressure medium line. This arrangement for the supply of pressure medium is suitable in particular for cylinders of small size whose casings have only a small wall thickness or in which the pressure medium lines are to be conducted near to the casing of the cylinder.
