A cold start valve for a hydraulic circuit has a valve slide with two counteracting control faces. It is possible to load a first control face with a control pressure and to load a second control face with a feed pressure. In addition, the first control face is loaded with the spring force of a valve spring. A damping space is configured to damp a stroke movement of the valve slide. The damping space is delimited by a damping face formed on the valve slide and oriented in accordance with the first control face. The damping face is configured to be loaded via the damping space with a damping pressure to damp the stroke movement. The damping space is connected in a throttled manner to a pressure space. The second control face of the valve slide is configured to be loaded with the feed pressure via the pressure space.

In a swash-plate type hydrostatic piston engine, a drive unit () and a swash plate () are received by a pot-shaped housing (). According to the invention, the pot-shaped housing () is configured such that it is able to receive drive units () of at least two rated quantities of a specific product series of the hydrostatic piston engine.

Combined pump housing for several rated quantities

A regulating device for a hydrostatic piston engine is provided. The regulating device () has an electronic control unit () for generating adjusting signals. An adjusting position of the hydrostatic piston engine scanned by a feedback element () is detected by a sensor element () of the electronic control unit () without contact.

Regulating device for a hydrostatic piston engine with electronic control unit

The invention relates to a hydrostatic piston engine comprising a cylinder barrel () inside of which a first group of cylinder bores () and a second group of cylinder bores () are made. The cylinder bores of the first group () can be connected to a first hydraulic circuit, and the cylinder bores of the second group () can be connected to a second hydraulic circuit. The cylinder bores of the first group (), and the cylinder bores of the second group () are realized in the cylinder barrel () on a shared partial circuit ().

Hydrostatic piston machine with two hydraulic circuits

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 (&#x2032;) 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.
