Abstract
The invention relates to a connection block for a hydrostatic piston machine which is provided for simultaneous operation in a first hydraulic circuit and a second hydraulic circuit. A first working pressure duct () and a second working pressure duct () are formed in the connection block, via which ducts respectively a first and a second working line () of the first hydraulic circuit can be connected to respectively a first and a second kidney-shaped control port of a control plate () of the hydrostatic piston machine. Furthermore, a third working pressure duct () and a fourth working pressure duct () are formed in the connection block (), via which ducts respectively a third and a fourth working line (') of the second hydraulic circuit can be connected to respectively a third and a fourth kidney-shaped control port (′) of the control plate of the hydrostatic piston machine. A common feeding pressure duct () is provided in the connection block (), it being possible for the common feeding pressure duct () to be connected to the first to fourth working pressure duct () respectively via a separate feeding device.
