摘要： A valve unit has a plate-shaped valve body with a closure section and a connection section. The valve body has a cutout surrounded by a frame. The closure section has a closure tab that, beginning at a first fastening section at the frame, projects into the cutout. The connection section, beginning at a second fastening section at the frame, projects into the cutout and has a contact tab and a fastening point. The first and second fastening sections are arranged opposite each other at the frame along a longitudinal axis of the valve body. A filter head for the valve unit has a valve seat for a seal body of the closure section of the valve body. A fastening pin of the filter head fastens the connection section of the valve unit. A contact region of the filter head contacts a positioning region of the valve unit.
