Abstract:
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.
