摘要

The valve has a hydraulic bushing (2) with an elongate hole (3) limitingly extending in a circumferential direction. A screen insert (12) i.e. metal band, is inserted in the elongate hole and protects the elongate hole. The screen insert includes a frame (15), which is fixed relative to an inner edge of the elongate hole and receives a screen e.g. aluminum sheet or plastic mesh. The frame is designed as a plastic injection molded part. An elastically deformable retaining bracket extends from an outer edge of the screen insert. The bushing is position-orientedly provided in a housing.
