Abstract
In the stationary part () of an axial piston machine, a first flow duct () and second flow duct () intersect with the central axes () and (). A valve body () having a valve cone () and a tubular guide piston which can be displaced in relation to the valve cone is situated in the extension of the central axis () of the first flow duct (). The valve body () bears against a first valve seat () which is surrounded by an expanded section (). The entire valve body () moves in a tubular partial housing () which is connected to the stationary part () in a sealed manner via a seal (), a screw connection () and a flange () which rests on a shoulder () of the stationary part (). A first compression spring () and a second compression spring () serve to support the valve body () and its parts in relation to one another. An extension stem () passes through the tubular guide piston and guides the second compression spring (). The tubular partial housing () sits in a bore () of the stationary part (). Two valves Vand Vare formed, the valves setting flow paths between the first flow duct () and the second flow duct () which differ according to pressure ratios.
