The invention relates to an expansion machine (), comprising an output shaft () and a shaft sealing ring () that interacts with the output shaft. The expansion machine () has an inflow region () and an outflow region (). During operation, a working medium flows through the expansion machine (), wherein compressed working medium flows into the inflow region () and expanded working medium flows out of the outflow region (). The shaft sealing ring () separates a valve space () filled with working medium from a surrounding space (). A valve () is arranged in the expansion machine (). The pressure in the valve space () can be controlled by means of the valve ().

Expansion machine having a shaft sealing ring and a valve

Three-way valve with a valve housing and a closing body arranged in a longitudinally movable manner in the valve housing. An inlet channel, a first outlet channel and a second outlet channel are formed in the valve housing. The closing body interacts by longitudinal movement with a first valve seat formed in the valve housing and thereby opens and closes a first hydraulic connection between the inlet channel and the first outlet channel. Furthermore, the closing body interacts by longitudinal movement with a second valve seat formed in the valve housing and thereby opens and closes a second hydraulic connection between the inlet channel and the second outlet channel. A throttle is formed in the second hydraulic connection.

Three-way valve

Gate valve () with a valve casing () and a closing body () arranged longitudinally movably in the valve casing (). An inlet channel () and an outlet channel () are formed in the valve casing (). The closing body () via longitudinal movement cooperates with a valve seat () formed in the valve casing () and hence opens and closes a hydraulic connection between the inlet channel () and the outlet channel (). The inlet channel () and the outlet channel () are each formed as a spiral.
