摘要： 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.

摘要： A filter apparatus is for use with a hydraulic machine. The filter apparatus includes a connecting part and a filter cartridge. The connecting part includes a sealing face, which is configured for sealing abutment on the hydraulic machine. An input connector and an output connector are arranged within the sealing face. The filter apparatus further includes a separate retaining part on which the filter cartridge is fixedly received. The connecting part has a pivoting appendage extending along a pivot axis on a side of the connecting part facing away from the sealing face. The retaining part is fluid-tightly adapted to the pivoting appendage such that (i) its pivoting position with respect to the pivot axis is continuously adjustable relative to the connecting part, and (ii) between the retaining part and the pivoting appendage, a first and a second pressure chamber are arranged.
