摘要： The present invention relates to a two-stage valve for controlling fluids, in particular a hydraulic fluid. The valve includes an actuating element, a pilot stage having a first valve seat and a first closing body, which is connected to the actuating element, and a main stage having a second valve seat and a second closing body. The second closing body is provided with a fastening region and a main region having a passage opening. The first valve seat is arranged at the passage opening. The second closing body is connected to the actuating element via the fastening region. The fastening region is designed elastically in such a way as to open the pilot stage by elastically deforming during actuation of the actuating element.

摘要： An injection-molded part according to the invention has at least one thermoplastic inlay part and one thermoplastic composite element injection-molded onto the inlay part. The at least one inlay part on its boundary face with the composite element has at least one raised feature for material-locking sealing between the inlay part and the composite element. The raised feature protrudes with a height H1 into the composite element and forms a narrowed cross section in the composite element having a height H2. The at least one raised feature, on its flux leading end, has a first chamfer, and the ratio of the height of the narrowed cross section to the height of the raised feature is in the range between 0.6 and 0.9.
